Do-it-yourself propane roof burner. Do-it-yourself gas burner for roofing. Instructions for use

For the device of a soft roof, the deposited materials are considered the best heat and water insulators. This procedure involves the use of a roof burner. Such work is very complex and long, but as a result, you can create a very reliable and durable coating. Therefore, for work it is necessary to choose exclusively proven and highly quality equipment.

What is a roof burner

A roofing gas burner is a special device designed for the installation of welded roofing materials. Besides, using such equipment some elements are heated, surfaces are dried, paint is fired. The standard gas burner model includes the following elements:

glass made of heat-resistant metal alloy;
gas supply wire;
igniting nozzles protected from the wind.

Gas-burner for the roof is a compact device with strong handles for transportation. It has a relatively small weight (up to one and a half kilograms) and is equipped with a convenient plastic or wooden handle.

Propane gas is often used as fuel, but diesel-powered devices can be found on sale. The substance enters the device through a gas pipeline. The gas supply and the intensity of the fire are regulated by a special valve, which is located on the body. The built-in reducer allows you to minimize fuel consumption and control its consumption.

All models of gas burners for roofing works equipped with an air suction system. This feature is required. To additional options that enhances comfort is the choice of operating modes. For instance when the propane roof burner stops, standby mode automatically starts to save gas. Such equipment is ignited with an ordinary lighter or matches.

Varieties of gas devices

For mounting bituminous roofing manual burners are used. Often they "eat" propane. Such equipment is very convenient to use, and the length of the flame is adjusted by a simple linkage. The safest are gas-air roofing burners.

Valve models are characterized by low weight, ease of operation. In addition, such equipment is easy to repair. Giving out an intense flame, they work great even in strong winds.

There are also acetylene roofing burners that operate on a mixture of oxygen and acetone. They are often used for welding.

Compliance with security measures

Due to the fact that you will have to work with fire, you need to be extremely careful and careful. To avoid unwanted problems, you must follow the following rules:

Manufacturers of equipment and its cost

Today on Russian market you can find different types of roofing burners, both foreign and domestic production. Consumers speak positively about the equipment of the Caliber and Donmet brands. The products of these companies are characterized by high safety and excellent quality. As a rule, these are cheap devices that are suitable only for minor roof repairs. The most productive and advanced equipment is produced by Poap and Rothenberger. These devices are equipped with convenient operation, a large number of functions and extensive control options.

If you need to make a simple repair, it is best to purchase a model worth up to 1000 rubles. In the range of 700-900 rubles, you can get very good products. Products high cost more performance and reliability. Some craftsmen, in order to save money, decide to make a burner with their own hands. As a result, they have equipment that is in no way inferior in quality to "purchased" devices.

Self-manufacturing of the device

A roofing burner is a very complex device. For self-manufacturing such a device will require the study of a large number of rules and the presence of some skills. One way or another, it is better to entrust some part of the work to professionals. This applies to the fuel storage vessel and fuel supply system.

As a torch, a divider and a metal rod are used. The handle must be made of heat-resistant wood. The gas supply wire can be made with your own hands from brass or borrowed from a welding system.

To Work with homemade equipment you need to be very careful, checking for malfunctions and fuel leaks. Even with an insignificant problem, it is better to immediately stop the roof processing.

When it is required to equip a soft roof over a large area, the application adhesive compositions becomes unproductive and costly. Some types of roofing materials - from the same oxidized bitumen - are difficult to glue, and the seam at the joints turns out to be unreliable. As alternative way installation, a propane burner for roofing is used - a tool for installing welded waterproofing. This device is very effective and versatile, justifies its use one hundred percent.

Types of gas burners

Of course, there are more than just propane burners. There is also a whole classification according to various criteria. Let's look at this in a little more detail.

The principle of operation of a gas burner

Propane burners work from gas cylinders, on which a reducer or other gas distribution device is installed. With a small amount of work for propane cylinders, they can be installed on the roof, in other cases they are placed lower, connected to the burners through hoses, the length of which should not exceed 15 m.

Burners are used not only for connecting rolled waterproofing materials but also other tasks. For example, for dismantling an old roof, removing paint, heating metal pipes before welding them, heating curing bitumen and other things - the equipment is multifunctional.

Interesting to know! Propane burners are devices for which combustible, explosive mixtures are used. That's why industrial production these devices are allowed only according to technical regulations, established GOST 17356-89.

The state standard regulates the following technical indicators:

shut-off devices that control the gas supply must be completely sealed;
propane must be supplied smoothly to avoid the possibility of an explosion;
devices must be equipped with wind protection to prevent arbitrary attenuation of the flame;
it is required that the device is reliably switched off for a certain time;
thermal power limits are set.

If you are interested in more detailed information, please refer to the text of the named document.

Gas burner design

Now let's look at how a propane burner works - what nodes are available and what they are for. As an example, consider a combined gas-air burner that draws air from the surrounding space.

Fuel Preheating Chamber- a container inside which an electric heating element with the ability to adjust the strength of the current supplied to it. This node can be installed optionally, for example, when it is required to perform work at negative air temperatures.
Burner body- this part of the device is made of heat-resistant steel, it mixes the fuel jet with air.
Nozzle– the element is connected to the body through a union nut with a hermetic seal.
control valve- a node that performs control over the value of propane pressure at any time. It is worth noting that during long breaks, the gas supply will be turned off automatically.
extension tube- it receives the combustible mixture from the flow separator. Last detail installed right behind the nozzle.
Mouthpiece- the shape of this element determines the width of the combustible mixture at the outlet of the nozzle. It is also designed to protect the flame from the wind.
control valve- regulates the supply of a combustible mixture, and, accordingly, the length of the flame escaping from the nozzle.
Pen, made of heat-resistant plastic - allows you to control the tool with convenience and safety.

In addition to the above, additional parts may be included in the package. For example, a set of sealing paronite gaskets, a replaceable injector, a connecting clamp for a cylinder.

Interesting to know! Propane burner bottle sold separately. Most devices are designed for use with 50 liter cylinders welded from steel. Technical standards for these cylinders are established by GOST 15860-84, which is still in force today.

The use of gas-air burners also requires a single-stage reducer to the cylinder, which will ensure the normal pressure of the supplied fuel. Also, you can not do without a rubber hose of the combined type. Product class - the first, according to the even older GOST 9356-75. The hose must have a thread braid and be 9 mm in diameter.

How to use the burner

The use of a roof burner is carried out in the following sequence.

Before starting, it is imperative to check the tightness of the seals. For this purpose, it is necessary to pass air through the burner.
If a leak is detected, then the o-rings must be replaced with new ones, smearing them with sealant. After this procedure, the burner can be used no earlier than a day later.
When starting, the first thing to do is open the valve for the air supply, then for the gas. Further, using the existing ignition system (piezoelectric element, lighter, match), the combustible mixture is ignited at the outlet of the nozzle.
The divider is moved to adjust the sufficient length of the torch, its width is adjusted with the mouthpiece.

Advice! If necessary, an adapter-bell for several working nozzles is installed on the mouthpiece.

Turning off the burner is carried out strictly in reverse order.

How to choose the right roofing torch

First of all, it is necessary to evaluate all the important performance characteristics of the device, which include:

gas consumption, kg/h;
output power, kW;
the maximum possible width of the heated section of the roofing material or other roofing material that is used for the installation of a soft roof;
possible limits of flame (torch) length, mm;
nominal temperature heating of the surface, °С;
fuel consumption in kg/sq.m. laying surface;
device weight.

Of course, everyone will look at the most important characteristics for him, but first of all, you should still pay attention to the usability of the equipment. The simplest example is if you try to work with a burner for a long time, the weight of which is 1.5-2 kg, then your hand will get tired quickly enough, and the work efficiency will decrease significantly. By the same reasoning, one can also determine the length of the torch - they usually focus on a value of 300-900 mm. At maximum length The burner can be safely operated while standing.

A number of characteristics should be selected according to the heat capacity of the laid soft roof. For example, for an ordinary roofing material, working temperature 160-180 degrees, while for welded materials this will not be enough, because their operating temperature is 300-350 degrees.

The performance of the burner can be calculated using a very simple formula, in which the following quantities are involved: W is the thermal power of the equipment; V - fuel consumption; Q is the calorific value of propane, which is equal to 18.88 kWh / kg; n is the number of nozzles (nozzles) through which the flame is directed to the melted (heated) object, which is also the roofing material; η = 0.8 ... 0.91 is the efficiency of the heating process itself (this parameter will decrease with an increase in the number of active nozzles).

The formula itself looks like this: V = W/Qnη.

Table. The most popular propane burner models on the market today.

Is it possible to make a gas burner yourself

Now we will discuss the possibility of self-manufacturing a propane burner. Of course, this is all feasible, however, due to the requirements for sealing all parts, as well as the high accuracy of their manufacture, doing it in practice becomes very difficult. And if we take into account the low cost of factory devices, then this makes no sense. The most important part of the assembly work is the manufacture of the fuel supply and mixing unit, so parts from other devices are often used in such work. Let's try to describe the self-assembly process.

The diagram above shows the approximate structure of a propane burner - we have already disassembled the main structural elements. When assembling, we will not manufacture everything, and we will use spare parts from other equipment that you may have in stock. We will need:

steel valve - you can take it from any cylinder intended for storing liquefied gas;
plug - it is usually used when transporting gas cylinders;
from a blowtorch, we will borrow a jet, the nozzle of which should be 0.8 mm;
a metal pipe will also be needed - its inner diameter should be 10 mm, and the wall thickness should be at least 2 mm;
wooden handle - this part can be made by yourself.

Now let's break down our steps at work:

we fix the steel pipe, which we will use as a supply pipe, in the handle. This can be done with glue;
we make the body and the divider from a brass bar with a diameter of 20 mm. In the body, you need to drill two radial holes with a diameter of 5 mm, 4 holes are made in the divider rod (diameter - 1 mm);
assembly is carried out - the divider is pressed into the body with a large interference fit. A flange is installed inside the housing with a gap so that the inner diameter of the housing is 0.6 mm larger. The gap thus obtained will slow down the gas flow supplied to the igniter holes;
it is necessary to carve a nozzle from a steel rod;

Advice! In order to make a thin hole in the metal, we take a 2 mm drill and make a blind hole so that the tip does not reach the end of the metal 1.5 mm. Then a 0.4 mm drill is used to make the jumper. Further, the resulting hole is caulked with a hammer, after which the end face is undermined with sanding paper. This is done until a hole of the desired cross section is obtained, that is, until the nozzle can be put on the tip of the threaded tube.

a supply hose is put on the rear end of the tube and fixed with a metal clamp;
the working pressure is set on the reducer, and gas is supplied;
we wait until all the air comes out of the hose, after which we set fire to the gas, introducing it into the flame of the gas burner;
after that, you need to grind the end face. The flame on the burner must be 5 cm long;
body with a divider is put on external thread nozzles. The burner should produce an even flame without soot - to achieve this effect, you need to slowly turn the body along the thread on the nozzle;
loose threaded connection is sealed with FUM tape.

That's all. We hope that the material was clear and useful for you.

For repair and other roofing work, which involves melting mastics and laying roofing materials, you will need a special gas burner. The device is mainly used for the following tasks:

Heating and drying of roofing materials;

Cutting and soldering of metal;

Burning a layer of old paint.

Approximate structure of a gas burner

The gas burner has a fairly simple design. It is a glass made of metal and equipped with a nozzle and a handle, which is fixed on the body. For the manufacture of the handle, heat-resistant plastic or wood can be used. The gas enters the housing by passing through the gas pipeline. In most cases, propane under pressure is used to operate the burner.

The burner cup must be shaped to protect the flame from wind blowing.

The burner body has a valve that allows you to adjust the length of the flame and the intensity of the supplied gas. It is good if the burner has a gearbox that allows you to save gas.

Components of a roof burner

During the assembly process mechanical restoration practically not used. The burner is assembled from ready-made spare parts. For its manufacture we need:

Steel valve, which can be taken from a cylinder designed to store liquefied gas.
A cap that is used to transport gas cylinders.
Jet from a blowtorch with a nozzle diameter of 0.8 mm.
A piece of pipe one meter long with an internal diameter of 10 mm. and steel thickness 2 mm.
Wooden handle.

As a handle, you can use the handle from a burned-out soldering iron.

Step-by-step burner manufacturing process

The process of manufacturing a gas burner begins with the fact that we insert the supply tube, for which we will use a steel pipe, into the handle and fix it with glue. The divider and the body must be machined from a brass bar, the diameter of which should be 20 mm. In the finished case, two radial holes are drilled (each with a diameter of 5 mm.) And four holes in the divider rod (each with a diameter of 1 mm.).

When assembling, it is necessary to press the divider into the body with a slight interference fit. At the same time, the flange is installed inside the housing with a clearance, that is, the inner diameter of the manufactured housing must be 0.6 mm larger. bored diameter. The resulting gap is responsible for the deceleration of the gas flow, which is supplied to the drilled holes in the igniter.

Such nozzles are in purchased models.

To make a thin hole in our nozzle, you need to take a drill with a diameter of 2 mm. and use it to make a blind hole, which is 1.5 mm. does not reach the exit. Drill with a diameter of 0.4 mm. used for jumper. The resulting hole must be completely minted with gentle hammer blows. Then you need to sharpen the end. To do this, we take sanding paper and grind it until the desired cross section of the outlet is found, that is, until the nozzle can be put on the tip of the threaded burner tube.

At the end of the gas supply pipe, it is necessary to put on a supply hose made of fabric-rubber material. We fix the hose on the tube with a clamp. We set the working pressure, after which we supply gas. Wait until all the air is forced out of the hose, and only then bring the nozzle into the flame of a gas burner.

Attention! The nozzle is introduced into the flame without a body and a divider.

Next, you need to grind the end. The length of the burner torch should eventually be 5 cm. We put the body, together with the divider, on the external thread of the nozzle. Make sure that the burner gives an even flame, without signs of soot.

In order to achieve desired effect, slowly turn the housing on the nozzle thread.

If you received a free threaded connection, seal it with FUM tape.

Video. How does a gas burner for a roof work?

Hello! My name is Viktor Kaploukhoy. I am an engineer by training Technical University. Hobbies: IT, engineering and technology.

Literally in two decades, construction technologies have been updated, new building materials and tools have appeared. For example, the old faithful roofing material has given way to new roofing welded materials, which are better in all respects. Nobody will argue with this. And accordingly, a bucket with hot bitumen and a brush for coating went into oblivion, instead of which builders use today a gas burner for roofing.

What is a gas burner

This is a hand tool connected to a gas cylinder. It consists of:

A nozzle inside which a jet with a through hole of small diameter is installed. Through it, gas in the form of a flame is supplied to the place of surfacing or drying.
Cup. This is a device inside which a combustible gas is mixed with air (oxygen). There are many holes in the glass through which air is sucked into the flame zone. In addition, this device protects the flame of fire from the effects of wind.
A valve that opens the gas supply and regulates its pressure, and, accordingly, the length of the torch.
The main pipe that separates the torch from the handle that the welder is holding on to.
Handle made of plastic or wood.

Of course, to operate a gas burner, you need a hose connected to the cylinder and a reducer that lowers the gas pressure in the line. The gas pressure at the outlet of the burner is 0.1-0.15 MPa. The propane gas burner for roofing weighs a little, in the range of 1.0-1.5 kg. So it is convenient and easy to work with her.

How to make a burner with your own hands

In principle, the design of a propane gas burner is simple. The main thing is to collect the nozzle and glass. The rest of the elements and parts are ready-made components and parts that are sold at any hardware store. Therefore, it will not be difficult to make it with your own hands.

So, what is required to assemble the burner with your own hands.

Gas burner assembly

First of all, you need to cut an internal thread at one end of the copper tube using a tap of the appropriate diameter. Copper is not a very hard metal, so it will not be difficult to carry out this operation with your own hands. It will also be easy to screw the jet.

With a glass, everything is more complicated. To do this, you will have to cut one side of the pipe into several longitudinal petals (6-8 pieces), and then bend them to the center. You get a cone, while you don’t need to bring the petals to the end, you need to leave room for the main tube, on which the glass is put on. After that, the petals are pressed against the tube, where they are sealed. Slots remain between the petals, which will perform the functions of supplying air inside the nozzle. The length of the petals is approximately one third of the entire length of the glass.

Important! The jet should be located at a distance equal to the length of the petals. That is, a flame of propane and oxygen should form at the level of the slots.

A gas burner for roofing, or rather, its front part in the form of a nozzle is ready. It remains to assemble the back. To do this, you will need two M25 drives, made from a pipe with a diameter of 25 mm with threaded threads. In a one-sided drive, in a place where a thread is not cut, a cone is formed into which the back of the main tube is inserted. This can be done by heating the squeegee with an oxygen cutter, and tapping it from all sides.

A gas control valve is screwed into it. The second round, it is double-sided, is screwed into the valve from the other side. Be sure to wrap on the sealing material. For example, on a fum tape. An adapter from a threaded connection to a hose connection is screwed onto the rear end of the second spur. It makes no sense to make it with your own hands, because it is sold in any hardware store and is very cheap.

Now it remains to make a handle and install it on the prepared device. Handle options are plentiful. The main thing here is to comfortably hold the entire home-made device. For example, it can be cut from wooden board 5 mm thick, you can buy an ax handle and fit it to the size and shape. It is better to attach the handle to the sleds, because in the whole structure this is the most solid area. Optimally, this is the rear sway, because the control valve should be located slightly forward for ease of use.

You can attach a piece of wood to a metal tube in different ways.

Make a recess across the entire width to fit the diameter of the pipe, put the pipe into it and secure it with two clamps from a metal tape.
Install the crank on the side of the handle and also secure with clamps.

So, a do-it-yourself gas burner for roofing is made, you can connect it to a gas cylinder and test it. To do this, the hose is connected to the cylinder through a reducer, where it is fixed with a clamp. Its second end is threaded into the adapter, where it is also fixed with a clamp.

The cylinder opens, the propane supply through the gas reducer opens. And the last to open is the regulating valve on the injector. Gas should go through the jet with a characteristic sound. It is necessary to wait until the air inside the device is completely out. Then the gas stream is ignited. The valve near the handle regulates the torch in length and power.

Attention! Homemade gas burner for roofing - device heightened danger. Therefore, all operations performed must be approached with special care. This is especially true for the connections of all elements to each other. Full tightness must be observed.

Fire safety measures

Regardless of whether a factory-made gas burner or a home-made one is used, fire safety requirements must be strictly observed.

Keep a fire extinguisher on the roof when doing roofing work.
All work is carried out only during daylight hours.
When laying a soft roof with a gas burner, only one propane cylinder can be brought onto the roof.
Be sure to exclude its heating.
Do not overheat and ignite the laid roofing material itself.

These are the simple conditions that guarantee the safety of ongoing construction operations related to roofing with built-up materials. They are simple and easy to do, so there shouldn't be any problems.

Roof micro-burner– this movable structure with comfortable handles for the purpose of transferring it. Sympathy contains a small mass, up to 1.5 kilograms, and is armed with a handle that is comfortable for the purpose of activity from a log or plastic, up to 1 m long.

In the property of a gas, more than just a hydrocarbon is used. Someone is acting in the shell With the help of a gas pipeline. Regulate its supply and the length of the fire with the support of a special valve in the burner. In order to save exhaust gas, roofing games are equipped with a gearbox that controls fuel consumption.

Absolutely all gas burner systems take into account the concept of suction of the weather atmosphere. This is an inevitable role, however, to accept auxiliary ones, which carry out the service in the most convenient way.

In the main priority is the probability of coordinating worker regimes. For example, if a stop occurs in the service, an order of hope is introduced and fuel is saved. Each gas micro-burner lights up with ordinary matches or a lighter.

Less known, but also used for the purpose of roofing, are games that operate in diesel fuel.

What is this equipment?

The structure of the burner assumes the owner with gas supply regulators from which a railway with a mixer at the end is obtained. The micro-burner is connected with a rubber sleeve to the hydrocarbon-slide gas cylinder using a pressure regulator.

In the main, tamed gas games are used to heat the plane and fuse various substances. Gas game to accept 2 types with violent supply of the atmosphere and non-forced.

These types of burners have the following characteristic industrial properties:

Atmosphere supply in a gas burner with forced supply is performed in the following way, the air is supplied with the support of a propeller or a compressor. The advantage of this kind of game is the probability of a clear torch option. With the minuses, the difficulty of installing the device.
In burners that do not have a forced supply of atmosphere, the air is supplied through the hole in the diffuser freely due to the number of gas supply. The uncomplicated structure makes it possible to make it personally. It is allowed to rank among the minuses the inadmissibility of a clear torch option.
The gas micro-burner starts with a tan jet of gas, which is obtained from the diffuser, in some modifications, auto-ignition is taken into account.

The device and principle of operation of the burner

The design of the gas game consists of the following elements:

Metal cup with convex holes according to the sides.
Nozzle for spraying gas.
Plastic or wooden holder.
Rubber sleeve with the aim of the cart gas to the body of the game.
Valve for regulating the supplied gas and the length of the fire.

In connection with the modification, the game has the following differences:

The fuel supply is forced and non-injector.
Power and gas consumption.
The amount of fire supplied. Accept single-flame and multi-flame.
The method of using the device is easy and electromechanized.

The length of the game in relation to its installation is from 0.8 up to 1 meter, the weight is approximately 1.5 kg. In addition, due to modifications, gas games have every chance of being equipped different regimes fuel economy.

Roof burner models

For work according to the laying of the roof, the conditional type of device of the following modifications is used:

GG-2 propane micro-burner for the preparation and implementation of waterproofing works. Excellent for small scale roofing work. Recommended for young professionals. Basically low price.
GG-2U the similarity of the previous modification is distinguished by the Kurguz gas line. It is mainly used in inaccessible areas near the roof.
GG-2S seems to be a high quality burner, and besides it functions in propane. Contains 2 valves in order to clearly regulate the order of operation and the likelihood of operation in very windy weather.
GS1-1.7 contains a small mass, and the volume appears to be multi-purpose. It is used for the purpose of drying and fusing substances into the roof. It makes it possible to heat the plane up to FOUR Hundred degrees.
GK-1 the air-propane micro-burner is armed with a depressing cup and a gas supply lever. It is used for the purpose of pulling out the coloring by firing in wood surfaces and waterproofing the roof.
GS1-1.0 contains a simple mass and small volumes, which makes it possible to use it for the purpose of waterproofing roofs with a huge slope.
GGS1-0.5 it is mainly used for the purpose of small repairs of the roof and for economical use of gas in the project.
GGS4-1.0 contains 4 cups of fire supply. It seems economical and allows 1 person to treat a serious allotment of shelter due to a short period of time.
GV-3 It is used mainly for the purpose of heating metals for their welding or soldering.
GV-111R used for the purpose of fusing bituminous narrow-web substances into the roof. In addition, they are used for the purpose of firing the previous color in different surfaces.
GV-50, GV-900 comfortable and free in operation, they are distinguished by the length of the torch.
GV-500 I use for the purpose of fusing bituminous substances. It makes it possible to warm up the heated plane up to THREE hundred degrees.
GSV-850 contains an injection type of fuel supply. The micro-burner is equipped with a valve for a clear gas supply option and a flame length adjustment lever.

It is necessary to direct interest in such characteristics, as well as:

Fuel requirement.
Flame size.
Heat performance.
Weight and length.

Application of gas burners

For the purpose of repair work and adaptation of the shelter with bituminous substances, a gas burner is mainly used. Approximately 600 square meters of welding material can be placed next to a high-quality burner due to 8 hours of working time.

Performing work according to adaptation and repair work shelter different types with the use of a gas game must be laid in accordance with absolutely all laws of fire protection.

For works according to the laying of different areas of the roof using a gas game, accept the established limits similar to the following:

It is possible to lay no more than 500 square meters at a time.
When laying more than 500 m. 2, the presence of fire hoses with water is necessary.
Has access to fire hydrants, must appear from the four edges of the mulched roof.
Water supply With the help of a fire hose must be taken to each point of the laid plane.

Stages of work when laying material using a roofing burner

The procedure for laying bituminous or so-called soft build-up materials using a gas game consists of the following steps:

Cleaning the roof plane from debris.
Unwinding rolls in the plane of the roof with an overlap of friend to friend is in no way less than 10 cm for the purpose of marking. Subsequently, that the rolls must be wound and numbered.
Priming the plane with prime in order to pull out microcracks, spalls and bind dust.
Having made the marking of the plane and its primer, the rolls are unwound over time and heated by a gas burner in order to fuse into the plane.
At the final stage of the laying motion, it is necessary to heat the seams of the deposited substance with a burner.

After the fusion of substances, in order to prevent wrinkles, the covered plane must be turned with a roller.

How to make a gas burner with your own hands?

A gas burner can be made personally in domestic circumstances for the purpose of this, the following components will be needed:

Rectifier with pressure reducer to control the gas supply. It is allowed to take it from an oxygen cylinder.
Cork that is used next to the transportation of gas cylinders.
Liquid fuel jet with a nozzle diameter of 0.8 millimeters. It is allowed to take it with a gasoline blowtorch.
A piece of iron track is a variant of the tube with a length of the only unit with a diameter of 10 millimeters and a wall width of 2 millimeters.
Handle with slightly heat-permeable substance. Mostly from a log.
Shell and gas diffuser game (cup). It is allowed to carve them from a brass bar with a diameter of 20 millimeters.

The further procedure for installing the gas game consists of the following steps:

A road is inserted into the handle made and fixed with glue.
In the chiseled case, it is necessary to drill 2 radial holes with a diameter of 5 millimeters. In addition, it is necessary to drill 4 holes in the body with a diameter of 1 millimeter in the divider rod.
The next production step of the game is enough to sketch the dissecting rod in the shell. The completed shell needs to be fixed into the rail.
It is necessary to cut the threads with a tap into the routes with the inserted body and screw the nozzle.
A gas-air hose is connected to a different outcome of the route and secured with a clamp.

After installing the gas game, you need to unscrew the specific oxygen rectifier and wait until the blue fuel squeezes out the airspace in the sleeve. Subsequently, what to burn with matches the flow of gas from the body (glass).

Safety rules for working with gas burners for roofing

When operating with a gas burner, it is necessary to strictly comply with the laws of security:

Before the basis of the operation with the device, it is necessary to make an inspection of the game in the object of automatic defects and losses. ant. gas income. Micro burner for roofing
The arson game cannot be carried out by standing in front of the nozzle of the glass.
Work must be carried out using canvas gloves, overalls and footwear.
When working with a gas burner, it is necessary to observe so as not to overheat the welded raw material. Thus (in the same way as overheating can cause the destruction of a substance.
On workplace where the micro-burner is used does not have to be third-party objects, especially flammable ones.
When serving with a gas burner, fire extinguishing resources must be located near the laying area.
A repairman operating with a device is in no way obliged to move with a singed burner on anyone other than the mulched plane.

The principles of safety when working with a gas burner must be respected at all times and indisputably. oh, thus, as well as a given guarantee of the unity of the functioning Person and the people around him.

The gas micro-burner seems to be a necessary assistant next to laying the roof with gentle substances. A similar device, as well as a gas micro-burner, has extensive use in the system and correctional boats.

As well as the norm, gas games are used to fuse roofing materials, burn out color in different surfaces, welding and soldering different metals. Game take various kinds systems for the purpose different types works.

It should be immediately noted, after all, that it is much easier and more harmless to purchase a finished burner than to make it personally. However, if you accept self-confidence and passion to always do it with your own hands, in this case it is allowed to try.

Gas micro-burner- this is a difficult apparatus and for the purpose of this, in order to produce it, some skills will be needed, and the detailed implementation of a large number of laws. However, always, after all, it is more correct to save the Element activity for the purpose of specialists. This primarily concerns the organization of supply and storage in order to conserve gas.

For the production of a torch, a metal base and a gas diffuser are used. Attach them to the handle from a heat-resistant log.

The hose for the purpose of supplying gas is drawn from a gas welding organization or personally grinded from brass.

Despite in that case, what about appearance a roofing micro-burner, selected by one's own handles, differs significantly from shop counterparts, and sympathy will manage with its own main functions.

But next to the service with it, it is especially necessary to carefully concentrate interest in the smallest gas leaks or other malfunctions. And including a number of minor issues, the service must be interrupted immediately. Information roofing game work in low fuel.

They are especially important for the purpose of operating near a large temperature minus, in this case they are supplied with integrated fuel heating. They are fully automated and ready to work with gasoline of various properties.

Diesel roofing games are equipped with a high-pressure blower concept which guarantees stable and reliable ignition and reduces the formation of soot.

Burners in low fuel stand out fruitfully from gas counterparts. In diesel fuel, the fuel acts into the chamber before high pressure, which leads to splashing of water. And the finest particles previously sprayed are ignited at the exit from the nozzle, forming a fire.

In connection with what, the micro-burner is connected to the compressor and the tank with gasoline next to the support of oil-and-gasoline resistant hoses.

In a home workshop or garage, there is often a need to use a high temperature burner. The application for it is the widest - from soldering to roof repair. Not to mention the need to heat up the metal part for processing.

During locksmith work on metal, a gas burner can heat the workpiece for the purpose of subsequent hardening. If you are engaged in electric welding, when working with some metals, it is necessary to warm up the place of the future seam.

Tool stores sell a variety of tools for safe work with fire. A propane burner can be of any size and any configuration. The size of a ballpoint pen for jewelry soldering:

Or a multi-nozzle ramp for heating bitumen on the roof:

The advantage of industrial options is the safety certificate. However, there is nothing in the design that cannot be repeated at home. Since any product in the store costs a lot of money, we will tell you how to make a burner with your own hands.

Important! Homemade fixtures for working with fire carry a potential hazard. Therefore, a propane burner manufactured without technical expertise is operated at your own peril and risk.

How to make a burner yourself

Let's take a closer look at the nuances that you should pay attention to when making a burner.

First of all, it is necessary to use refractory metals. A properly adjusted burner can produce up to 1000 ° C, so the nozzle must match the temperature of the flame;
It is important to choose a reliable working crane. If something goes wrong, the gas supply is first of all shut off, and the danger is eliminated. If the tap skips, you will not be able to quickly extinguish the flame;
The connection to the gas source (canister with valve or 5 liter propane tank with reducer) must be reliable. It is during the operation of low-quality shutoff valves that most accidents occur.

Consider typical scheme and the principle of operation of the injection burner:

Gas is supplied under pressure through the hose (1). Usually propane. The pressure is formed due to the evaporation of liquefied gas in the cylinder, and it is enough to organize a stable and directed flame. A reducer is not required, the amount of gas is regulated by a working valve (2).

The stopcock is located on the cylinder valve. Its function is only to open / close the fuel supply, the rest of the adjustments are made using a working valve.

The gas supply tube (3) brings the jet to the nozzle and ends with a nipple (6) that sets the direction of the flame. The nipple with the tube, in turn, is located in the so-called insert (5). It organizes the mixing of gas with atmospheric air.

The insert with tube and nipple is fixed in the nozzle with a screw. As a rule, the burner is collapsible for cleaning and maintenance of the nipple.

The formed air-gas mixture is sent to the nozzle nozzle (8), where the mixture is additionally saturated with oxygen from the air. Ventilation openings (7) are provided for combustion stability.

The do-it-yourself burner is made according to the drawing.

Dimensions are designed to work with cylinders up to 5 liters.

We will tell about the device of the liner separately, the dimensions are indicated on the drawing:

The liner tube (1) must be half a millimeter smaller in outer diameter than the inner diameter of the nozzle. A washer (2) with holes for air supply is welded inside. The sleeve (3) is designed to fix the tube with the nipple.

The design feature is that by moving the tab inside the nozzle, you can adjust the suction of air through the ventilation holes. This allows you to control the temperature of the flame over a wide range.

The nozzle can be made from steel pipe, but it would be better to carve it from a steel blank on a lathe. The shape of the nozzle should be slightly narrower at the exit, then the flame will be forced and the temperature in the combustion zone will be higher. Type 45 alloy steel is used.

There are two ways to make an insert: You can assemble it from two tubes and a steel washer with holes. The design is soldered with refractory solder, with abundant fluxing. And you can carve it entirely from a steel blank. The second option is preferable.

The supply tube is copper or brass. On the side of the hose connection, a flange is made (concentric grooves can be made for better fixation). A suitable nipple is screwed into the working end. You can take it from a stove, or a gas burner from a household stove.

Important! When using a nipple from cooker remember that different nozzles are included in the kit. For natural or liquefied gas.

We will use the second option. When the burner is ready with your own hands, it is necessary to carry out initial debugging.

The burner is set up for the gas that will subsequently be used. The insert is lightly fixed with a screw so that the ventilation holes are half blocked.

Having slightly opened the working valve, and moving the insert, we achieve an even, powerful flame. Then we finally fix it in the nozzle.

If you did everything right, the temperature at the outlet of the nozzle will reach 1100 ° C.

We pass from theory to practice. How to make a gas burner using improvised materials:

The nozzle is made from a classic car pump. Such items often lie around in the garage idle.
The steel used is excellent, the size is suitable for a gas burner.

In the back part we cut a “rose”, the ends are reduced to the center. The feed tube will be inserted into this bundle.

The part came from a construction foam gun.
This fixture is reusable, so the steel there is strong, and coated with refractory chrome.

The thickness of the tube is almost 1 millimeter, which is quite enough for rigidity.

At the end of the gun tube is a jet with a ball valve to form foam. The ball is knocked out with a thin awl, or gypsy needle. The resulting hole is sufficient to supply gas to the nozzle. The tube with the nozzle is connected by semi-automatic welding.

To connect the structure with a working faucet, ordinary plumbing threaded spurs were used. It's simple water pipe, no special steel is needed here. The part of the burner where the tap is located does not heat up to critical temperatures. A ball gas valve had to be bought;
The holder is literally made from scrap metal. Handle from the footboard of a motorcycle. Lightly processed with a grinder, we get the optimal shape. Clamp for attaching to the burner pipe - from the steering wheel of the same motorcycle.

Finally, the handle is put on a motorcycle handle. And the thermal insulation is good, and the burner fits snugly in the hand.

The production took one day off and 100-120 rubles to buy a tap and a fitting for connecting to a hose.

As a bonus, check out the blueprint for a tried and tested miniature contraption:

A gas burner for soldering is made from a needle from a dropper. Connects to a lighter refill bottle.

Output! Homemade gas burner - a reality. Just be careful when using!

A simple and effective way to make a gas burner with your own hands - video

The device of a soft roof with the help of adhesive compositions is an unproductive occupation, especially if the coverage area is more than 100 m 2. Some types of coatings, for example, from oxidized bitumen on a glass polymer basis, are generally difficult to glue, and the strength of the seam is very low. However, there is an alternative - melting a soft roof with a jet open flame. The method is effective and versatile, but its implementation requires a special gas burner for roofing.

Classification of gas burners

Burners can be not only gas, but also liquid. In the latter case, they run on diesel fuel, but they are less common, since their effectiveness is manifested only at low outside temperatures of + 10 ... + 15ºС.

This type of burner is distinguished by the following features:

According to the type of combustible mixture used. In addition to the mentioned liquid and gas, combined designs are also used, when in working area simultaneously with combustible gas (propane and, much less often, acetylene), air or oxygen is supplied.
By the number of working nozzles. Gas burners for roofing can have from 1 to 4 nozzles. In the latter case, the technological capabilities of the device are expanded (for example, the working width roll material), but at the same time the consumption of combustible gas increases.
By the presence or absence of a gearbox. Gearless burners, although structurally simpler, do not have the function of regulating the gas flow, which is inconvenient in the practice of their application.
According to the method of igniting the gas jet. Modern designs The considered devices have a piezo ignition unit, which is much more functional than using matches or a lighter for the same purposes.
According to the design of the gas supply tube. It can be straight or bent at an angle, normal and shortened length.

Such burners work from cylinders. A reducer or other gas distribution device is installed on the cylinder. For propane cylinders, with a small amount of work, they can be installed on the roof, in other cases, hoses are used, the length of which should not exceed 12 ... 15 m.

Most propane roof torch designs can be used for other purposes as well, such as removing old paint (successful replacement of a blowtorch), heating copper or brass pipes before welding them, heating cooled bitumen, etc.

Being devices that use combustible and explosive mixtures, industrial versions of gas burners are manufactured according to technical requirements GOST 17356-89. The following performance indicators are normalized by the standard:

One hundred percent tightness of the shut-off organs that control the gas supply;
Smooth supply of propane;
The presence of anti-wind protection against spontaneous blowing;
Reliable shutdown of the device and response time;
Limits of thermal power regulation.

Design

Gas burner units for roofing work are considered on the example of a combined gas-air burner with air suction from the environment. The device of such a device includes:

A chamber for fuel preheating, in which an electric heating element with a current regulator is hermetically mounted. The unit is completed optionally, if the majority of roofing operations will be carried out at low ambient temperatures.
Housing made of heat-resistant steel, in which the propane jet is mixed with air.
Nozzle, connected to the body by means of a union nut, which has a reliable seal.
A control valve that continuously monitors the current propane pressure entering the burner mixer. During long breaks in operation, the gas supply is switched off.
An extension tube into which the ignited mixture enters from a flow divider mounted immediately behind the nozzle.
A mouthpiece, the shape of which determines the width of the combustible mixture exiting the burner nozzle. The mouthpiece also provides wind protection for the jet.
A valve that controls the supply of the gas-air mixture and the length of the flame.
Handles made of heat-resistant plastic.

In addition, a gas burner for roofing may include a replaceable injector, a set of paronite gaskets and a connecting clamp for a cylinder. Most of the designs of these units are calculated for propane cylinders (steel welded, with a capacity of 50 liters in accordance with GOST 15860-84). To operate such burners, you will also need a single-stage balloon reducer (for example,) and a first-class combined rubber hose according to GOST 9356-75 with a diameter of 9 mm, with a thread braid.

The operation of the roof burner is carried out in the following sequence. Before starting, the tightness of the seals is checked, for which air is passed through the burner. If necessary, the sealing rings are replaced, seated on the sealant, and used no earlier than a day later.

When the propane burner is turned on, the air supply valve is first opened, then the gas supply valve, and then the air-gas mixture is ignited with a lighter, match or piezo ignition system. By moving the divider, the required length of the torch is adjusted, and with the help of the mouthpiece, the width. If required, an adapter in the form of a bell with several working nozzles is installed on the mouthpiece. The device is turned off in the reverse order.

Choosing a torch for roofing

Main operational characteristics gas burners for roofing are:

Propane consumption, kg/h.
Thermal power burners, kW.
Torch length adjustment limits, mm.
The greatest width of heating roofing material or other material used for laying a soft roof.
Nominal surface heating temperature, ºС.
Specific fuel consumption per unit of covered surface, kg/m 2 .
Burner weight, kg.

The parameters are selected for reasons of ease of use. For example, with a burner that has a mass of more than 1.5 ... 2 kg, it is simply inconvenient to work for a long time. In the same way, they are determined with the length of the torch. Usually this parameter is taken within 300 ... 900 mm, and in the latter case, the burner can be operated while standing.

A number of characteristics depend on the heat capacity of the material of the soft roof. In particular, temperatures of 160 ... 180ºС are needed for the readiness of roofing material, and 300 ... 350ºС for welded materials.

For the performance of the process, the relationship between the thermal power of the burner W (indicated in the product passport) and the gas consumption V (the parameter is important for propane cylinders) is important. To calculate, you can use the dependence

V = W/Qnη, where:

Q \u003d 12.88 kWh / kg - the calorific value of propane;

n is the number of nozzles / sockets through which the burning gas-air mixture is directed to the heated (or melted) roofing material;

η = 0.8 ... 0.91 - efficiency of the heating process (with an increase in the number of nozzles, the efficiency decreases).

The most popular models of gas burners for roofing are:

GV-850. It has a regulating valve for gas supply, the length of the torch is easily controlled using a lever. The power of the burner allows it to be used efficiently also for heating metal-plastic pipes and for preparing copper alloys for welding or brazing. Price - 1700 ... 2200 rubles;

GGS-1-1.7. Popular due to its high temperatures heating, simplicity and reliability of design. Price - 2000 ... 2200 rubles. A variant of the same device, but with 4 sockets and a roller, will cost 12,000 ... 12,500 rubles;

GGS-1-1.0. The most compact of the domestically produced burners, allows you to work in confined spaces using a 5-liter cylinder. Price - 1300 ... 1500 rubles;

GV-250U. Differs in simplicity and reliability of a design, has the built-in device for compulsory suction of air. Price - 1100 ... 1200 rubles;

Kemper-1200 (Italy). Included are several nozzles with different width slots, the ability to work with propane cylinders with a capacity of up to 100 liters, an ergonomic shape of the handle. Price - 4400 ... 4700 rubles.

A few words about the possibility and feasibility of making the considered burners with your own hands. Due to the need for very careful sealing of all joints, as well as the high precision of manufacturing all parts, it is difficult to make such a device on your own. A particularly important area of work is the manufacture of the supply and mixing unit. Something can be borrowed from a welding gas torch, and a handle, extension cord and hose can be selected according to the recommendations of specialists.

For soft roofing, optimal hydro- and thermal insulation materials are those that are welded with a roofing burner. It is labor intensive and hard work, which, moreover, is performed at height. The result of high-quality installation will be a long service life of the roof. Therefore, only high-quality equipment is selected for work. In the article, we will consider the existing types and advantages of various roofing burners.

What is a roof burner

This is a special equipment for heating the built-up roof. In addition, with the help of a burner, the surface is dried, the workpieces are heated for construction works, fire building paint and are used in all work where it is required to heat elements or surfaces.

The gas burner for the roof consists of:

a metal cup made of heat-resistant material;
gas supply hose;
nozzles for ignition of a torch with protection against wind.

The roof burner is a mobile design with comfortable handles for carrying it. It has a small weight, up to 1.5 kg, and is equipped with a convenient handle made of wood or plastic up to 1 m long.

Propane is the most commonly used gas. It enters the body through a gas pipeline. Regulate its supply and the length of the flame using a special valve on the burner. To save gas consumption, roof burners are equipped with a gearbox that controls the fuel consumption.

In all designs of gas burners, an atmospheric air suction system is provided. This is a mandatory feature, but there are additional ones that make the work more comfortable. First of all, the ability to regulate operating modes. For example, when work is interrupted, standby mode is activated and fuel is saved. Any gas burner is ignited with regular matches or a lighter.

Less popular, but also used for roofing, are diesel-fuelled burners.

Application of gas burners

They are used in most branches of construction and industry.

The design of gas burners depends on the fuel on which they operate and on the area of application. But in general they are identical. The burner, consisting of a body, a lever for adjusting the flame of a valve for supplying fuel, is connected to a gas cylinder through a reducer. Some manufacturers supplement the designs of gas burners with additional flame wind protection and piezo ignition.

Types of gas burners

For laying roofs made of bituminous materials, hand burners are used. Most often, these are propane burners for the roof of a lever structure. They are easy to use - the length of the flame is easily adjusted by simply pressing the lever mechanism, switching to an economical mode of gas consumption.

During operation, the gas burner consumes a mixture of propane with air or with the addition of technical oxygen. Gas-air burners are the safest for operation. They provide sufficient temperature for roofing, heating metal parts, annealing paint and soldering cables.

Valve-type gas burners are easy to use, light in weight and do not cause difficulties in repair. By creating a high flame with high power, they make it possible to work even in windy weather.

There are also acetylene torches that run on a mixture of acetylene and oxygen. Most often they are used for welding work. They are designed in such a way that oxygen, in injection acetylene burners, is needed not only to maintain combustion, but also to supply acetylene.

In addition, burners differ in functionality and have different abbreviations:

GV 500

Are applied at roofing works. It is capable of creating a heating temperature of up to three hundred degrees, which is quite enough for fusing all bituminous materials;

GV 850

More advanced model. It has a valve for fine adjustment of the technical gas supply from the cylinder. And thanks to the lever, the length of the flame is easily adjusted during work. Its power is enough to melt metal-plastic pipes and refractory cables.

GV 3

Runs on propane. It is used for heating and welding of metal and hand soldering. The size of the glass diameter is 5 cm.

GGS1-1.7

The most versatile and most popular burner. Heats the surface up to four hundred degrees. It is used when laying soft roofing materials, road and waterproofing works. Power is 115 kW with fuel consumption of 9kg/h.

GGS1-1.0

Indispensable for work confined space and on a roof with a large angle of inclination. It is a good replacement for a conventional blowtorch. With small dimensions (length 50cm) it has great power, is safe, economical and convenient to use. Its power is 40 kW, and the gas consumption is 3 kg/h.

GGS1-0.5

Used for small roofing repair, soldering, welding cables. Due to economical fuel consumption, it can work with a five-liter gas cylinder. The power is 10 kW, the consumption is 0.7 kg/h.

GGS2-1.5

Equipped with two parallel sockets, thanks to which it has a high performance. Power 179 kW with fuel consumption 14kg/h.

GGS4-1.0

Or a spreader. It has 4 sockets, which provides simultaneous heating with a width of 1 meter and allows you to work non-stop. There are special hooks for the roofing material along the cuts; with their help, one person can perform all the work on laying it. Power 120 kW, consumption - 12 kg/h.

Gas burners are used in all types of construction and repair work and can heat surfaces up to four hundred degrees. In particular: gas-air injection burner GG-2, gas burner GVK 1, liquid fuel burner GRG-1, propane burner GSP-3, propane burner GVK-1-R, propane burner GSP-4 and others.

The price of gas burners for roofing varies greatly and depends on many factors: performance, additional features, from the ability to work with one or another fuel, as well as from the manufacturer. It is worth noting that they are inexpensive and available to most consumers.

What you need to know when working with a gas burner for a soft roof?

Consider this on the example of roofing work when laying roofing material:

first, the entire surface is cleaned - not only large debris is removed, but also fine dust;
for marking, sheets of roofing material are laid out on the roof with an overlap of up to 10 cm, after which it is twisted, and the edges of all sheets are fixed with a gas burner at the base of the roof;

during operation, a roll of roofing material is rolled out gradually, melting and pressing tightly to the roof surface. All wrinkles and bubbles under the material should be removed immediately. When working on flat roofs, this is done using a hand roller;
the final stage of work with a gas burner will be the heating of all seams of the roofing material. When heated, it melts, sticking tightly to the bottom sheet. Additionally, the seams are reinforced with a hand roller.

When a high-quality gas burner with adjustable fuel supply is used for work, up to 600 m of roofing material can be laid non-stop.

Important! It is allowed to use a gas burner for a soft roof at a temperature not lower than 15 degrees. If work is required at a lower temperature, an oil burner will be required.

Safety precautions when working with a roofing gas burner

Roofing work is required in special clothing and shoes with non-slip soles;
use the safety system;
Before use, the gas burner is carefully inspected. It is necessary to make sure that all structural elements are in good condition;
during the operation of the burner, there must not be a second gas cylinder on the roof. Also periodically it is necessary to check the tightness of the hose connection with the reducer and the cylinder;
when igniting the burner, in no case should you be in front of the nozzle;
adjust the height of the flame so that it does not touch the cylinder, hose or people;
when heating the welded roofing material, it must not be allowed to ignite;
only the lower part of the sheet should be melted, without softening the entire thickness of the material;
when igniting a propane burner, first open the valve half a turn and leave it to purge for a few seconds. And only then can the mixture be ignited and the height of the flame can be adjusted;
with a working gas burner, it is forbidden to leave the working area or climb the scaffolding;
to extinguish the burner, the gas supply is first blocked, and then the lock lever is lowered;
if the burner overheats or a backlash occurs, work is immediately stopped, the gas is shut off, and the burner is placed in a container of cold water to cool.

Buy a ready-made burner or make your own?

It should be said right away that it will be much easier and safer to buy a ready-made burner than to make it yourself. But if you have confidence in your abilities and love to do everything with your own hands, then you can try.

A gas burner is a complex device and in order to make it you will need certain skills and thorough adherence to many rules. But still, part of the work is best left to professionals. First of all, this concerns the supply system and gas storage tanks.

For the manufacture of a torch, a metal rod and a divider are used. They are attached to the handle made of heat-resistant wood.

The gas supply hose is borrowed from the gas welding system or independently machined from brass.

Despite the fact that outwardly a do-it-yourself roofing burner will differ significantly from store-bought counterparts, it will cope with its main functions.

But when working with it, you will have to pay special attention to the slightest gas leaks or other malfunctions. And even with a minor problem, work should be stopped immediately.

Roof diesel burner

These roofing burners operate on liquid fuel. They are especially relevant for operation at a large temperature minus, in which case they are equipped with built-in fuel heating. They are fully automated and are able to work with fuel of various qualities. The diesel rooftop burners are equipped with a high-pressure blower system that ensures stable and safe ignition and reduces soot formation.

Liquid fuel burners are structurally different from gas counterparts. In diesel fuel, the fuel enters the chamber under high pressure, which causes the liquid to be atomized. And the smallest particles already sprayed are ignited at the outlet of the nozzle, creating a flame. In this connection, the burner is connected to the compressor and the fuel tank using oil and petrol resistant hoses.

The oil fired roof burner is designed to operate under the following conditions:

at ambient temperature from - 25 to + 40 degrees;
at atmospheric pressure- 101 kPa;
if necessary, flame temperatures up to 600-800 degrees.

In this case, the approximate consumption of diesel fuel is 10 l / 100 m2 of area.

How to work with a diesel roof burner:

check the serviceability of all structural elements;
turn on the compressor to supply air to the nozzle. Then, having opened the fuel supply valve, bring a special igniting tourniquet to the nozzle. After igniting the diesel fuel supply tap, adjust the flame level.
