Gas burner for roofing work: instructions, drawing, photo. Gas-burner

A gas torch for roofing work is an indispensable tool when it is necessary to waterproof the roof surface. Before use, it is recommended to familiarize yourself with the principle of use and some nuances that will prevent burns and unforeseen situations.

Gas burner device

For arranging a soft roof, experts recommend using burners that have one nozzle. This ensures the most uniform heating of the material, and also saves fuel. According to professionals in their field, devices with several nozzles heat up unevenly. During work, you may notice burning of the canvas in one place, while in another the material will not be warmed up enough. In terms of external characteristics, the burner is a glass equipped with a nozzle. The handle is attached to the latter. The glass is made in such a way that during operation the flame is not extinguished by the wind. The handle uses a rubberized material, which is sometimes replaced by hardwood. The standard length of such a device does not exceed 1 meter, while the weight, as a rule, is no more than 1.5 kilograms.

Some nuances of use

If you use a gas torch for roofing work, then you must take into account that the torch is controlled by a trigger. This applies to gas-air structures. At the same time, you can quickly switch between modes. This is to the liking of all craftsmen who quite often use changing the operating mode to the economical one. If you are interested in saving gas, you can put the device in standby mode.

To reduce propane consumption, a reducer is used. It is designed to stabilize the fuel flow, which allows for fuel consumption control. If you want to save resources, then you should purchase equipment with a gearbox, which reduces gas consumption by 30%. Air intake for combustion is usually carried out from the atmosphere. If the burner is in good condition and is also reliably protected from wind, then it can be used to lay 600 meters of roofing material within 8 hours.

Instructions for use

If you will use a gas burner for roofing work, then you must carry out several steps before doing so. Initially, the base for laying the material is prepared; for this, the surface is cleaned of dust and debris. If there is a need, the concrete screed should be leveled. Next, the surface is treated with a primer. At the next stage, you can begin working with rolled material, which is laid out to ensure overlap. The width of the latter can vary from 8.2 to 9 cm. This installation of waterproofing is only a fitting. During these manipulations, the rolls should be leveled and then rolled back. The material must be fixed at the base of the roof, during which a gas burner is used for roofing work. Now an assistant should be connected to the work. One of the craftsmen uses equipment to heat the surface of the base, as well as the lower surface of the waterproofing. While the second person is engaged in tightly pressing the insulation to the roof surface. In this case, the roll must be rolled out immediately. To prevent the formation of wrinkles and bubbles, the roll should be rolled with a hand roller. If peeling of the seams was detected, then a gas burner for roofing work, the photo of which is presented in the article, will eliminate these errors.

Safety instructions

The technician must remember that the equipment described is very dangerous if used incorrectly. During the manipulation process you will have to work with open fire. Any such equipment requires compliance with certain safety regulations. Therefore, you should never smoke in the workplace. Work should only be carried out after the cylinders, hoses, and gas burner have been checked for serviceability and suitability for use. A gas burner for roofing work must have sealed hoses. This also applies to the connecting elements between the cylinder and the burner. You should not start work if you do not have special equipment. This is especially true for safety shoes that have non-slip soles. During the described manipulations, it is unacceptable to place several gas cylinders on the roof surface at the same time. A gas burner for roofing work, the instructions for use of which are described in the article, is a fire hazardous equipment. That is why, before laying insulation, a sufficient number of fire extinguishers should be prepared, the functionality and serviceability of which should be checked in advance.

Operating rules

In addition to special shoes, the master must have special clothing, as well as a belt and walking bridges. When igniting equipment, it is prohibited to stand directly in front of the nozzle. The direction of the flame must be directed in such a way that it does not reach people on the roof. It is important to prevent fire from coming into contact with the connecting hoses and gas cylinder. A gas burner for roofing work, the drawing of which is presented in the article, must be used using a technology that involves preventing overheating and ignition of the materials being laid. When heating insulation using the equipment described, it is necessary to ensure that only the lower surface of the sheet melts. Softening of the entire thickness of the material is unacceptable. If you use a gas burner for roofing work, you can waterproof the roof system yourself. However, it is unacceptable to set fire to equipment using objects that accidentally caught fire. To do this, use only a lighter or matches.

When using a propane model, the valve should not be opened a full turn, but only halfway. After the specialist waits a few seconds, the fire can be ignited. After this, you can proceed to adjusting the flame length. A worker holding a lit burner in his hands must not leave the boundaries of the workplace, nor use scaffolding for movement.

Final works

The equipment must be extinguished in two stages: first, turn off the gas supply. The next step is to lower the locking lever. If you plan to interrupt the work for a certain period of time, the burner should not be left unattended. During this period it should be extinguished. If you plan a longer break, then the gas supply to the cylinder should be stopped.

Preventing unexpected situations

If clogging of the input channels of the mouthpieces is detected, the equipment must not be used. Failure to follow this rule may result in pops and kickbacks. If this does happen (a similar situation, by the way, can also arise if the burner overheats), then it is recommended to immediately stop working and also turn off the gas. The device must then be cooled by immersion in a tank of water.

Features of different burner models

After reading this article, you will understand what a gas burner for roofing work looks like. However, it is also worth knowing that various modifications can be found on sale. For example, GG-2 is used by amateur craftsmen and is intended for small-scale work. If you see a model of the GG-2 brand on sale, you will know that it differs from the ones described above only in the shortened gas pipeline. This equipment is simply irreplaceable when manipulating in hard-to-reach places. It can be used to seal junctions and joints. If you are going to do professional work, then the latest model will be a must-have for you.

Conclusion

When choosing equipment for laying insulation, it is worth checking whether the device has a gearbox for a gas burner for roofing work. This part of the design allows you to use fuel more economically. You should not save money by purchasing models without such an addition, because it can justify a slightly more impressive cost after some time of using the described equipment. Whereas if there is a need to waterproof only one roof, then it is not at all advisable to purchase a burner. It would be preferable to rent equipment. It will be cheaper, and therefore more profitable. Many masters use exactly this approach.

When it is necessary to equip a soft roof over a large area, the use of adhesive compositions becomes ineffective and costly. Some types of roofing materials - made from the same oxidized bitumen - are difficult to glue, and the seam at the joints is unreliable. As an alternative installation method, a propane torch for roofing work is used - a tool for installing built-up waterproofing. This device is very effective and versatile, and justifies its use one hundred percent.

Types of gas burners

Of course, there are not only propane burners. There is also a whole classification based on various criteria. Let's look at this in a little more detail.

The principle of operation of a gas burner

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

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

Interesting to know! Propane burners are devices that use flammable, explosive mixtures. Therefore, industrial production of these devices is allowed only in accordance with the technical standards established by 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 explosion;
devices must be equipped with wind protection to prevent arbitrary flame extinguishing;
it is required that the device switches off reliably within a certain time;
thermal power limits have been 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 components are there and what they are intended for. As an example, consider a combined gas-air burner that sucks in air from the surrounding space.

Fuel preheating chamber– a container inside of which an electric heating element is installed with the ability to regulate the strength of the current supplied to it. This unit can be installed optionally, for example, when it is necessary to perform work at subzero air temperatures.
Burner body– this part of the device is made of heat-resistant steel, in which the fuel stream is mixed with air.
Nozzle– the element is connected to the body through a union nut that has a hermetically sealed seal.
Control valve– a unit that controls the propane pressure value 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. The last part is installed immediately behind the nozzle.
Mouthpiece– the shape of this element determines the width of the combustible mixture at the exit from the nozzle. It is also designed to protect the flame from the wind.
Control valve– regulates the supply of the combustible mixture, and accordingly the length of the flame escaping from the nozzle.
Pen, made of heat-resistant plastic, allows you to operate the tool with convenience and safety.

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

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

To use gas-air burners, a single-stage reducer is also required for the cylinder, which will ensure normal pressure of the supplied fuel. You also cannot do without a combined type rubber hose. The product class is 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 roofing burner is used in the following sequence.

Before starting, it is imperative to check the tightness of the sealing gaskets. For this purpose, it is necessary to pass air through the burner.
If a leak is detected, the O-rings must be replaced with new ones, coated 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 air supply valve, then the gas supply valve. Next, using the existing ignition system (piezoelectric element, lighter, match), the combustible mixture at the exit of the nozzle is ignited.
The divider moves to adjust the sufficient length of the torch, and its width is adjusted with the mouthpiece.

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

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

How to choose the right burner for roofing work

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

gas consumption, kg/h;
output power, kW;
the maximum possible width of the heated section of roofing felt or other roofing material that is used for installing a soft roof;
possible limits of flame (torch) length, mm;
nominal temperature heating of the surface, °C;
fuel consumption in kg/m2 laid surface;
device weight.

Of course, everyone will look at the characteristics that are most important to them, but first of all you should still pay attention to the ease of use of the equipment. The simplest example is that if you try to work for a long time with a burner that weighs 1.5-2 kg, then your hand will quickly get tired and the efficiency of work will decrease significantly. Using the same reasoning, you can determine the length of the torch - usually they focus on a value of 300-900 mm. With the maximum length, you can safely work with the burner while standing.

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

Burner performance can be calculated using a very simple formula, which uses the following quantities: W – thermal power of the equipment; V – fuel consumption; Q is the calorific value of propane, which is equal to 18.88 kWh/kg; n – the number of nozzles (nozzles) through which the flame is directed to the object being melted (heated), also known as 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 models of propane burners on the market today.

Is it possible to make a gas burner yourself?

Now let's discuss the possibility of making a propane torch yourself. Of course, this is all possible, however, due to the requirements for sealing all parts, as well as the high precision of their manufacture, doing this in practice becomes very difficult. And if you take into account the low cost of factory-made 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 spare parts from other devices are often used for 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 discussed the main structural elements. When assembling, we will not make 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 designed for storing liquefied gas;
plug - it is usually used when transporting gas cylinders;
We will borrow a jet from a blowtorch, the nozzle of which should be 0.8 mm;
You will also need a metal pipe - its internal diameter should be 10 mm, and the wall thickness should be at least 2 mm;
wooden handle - you can make this part yourself.

Now let's look at our steps at work:

We fix the steel pipe, which we will use as a supply tube, in the handle. This can be done using glue;
We make the body and divider from a brass rod 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 great interference. A flange is installed inside the housing with a gap so that the internal diameter of the housing is 0.6 mm larger. The gap thus obtained will inhibit the gas flow supplied to the igniter holes;
it is necessary to machine a nozzle from a steel rod;

Advice! In order to make a thin hole in the metal, 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. A 0.4mm drill bit is then used to make the bridge. Next, the resulting hole is caulked with a hammer, after which the end is sharpened with sanding paper. This is done until a hole of the required cross-section is obtained, that is, until the nozzle can be placed on the tip of the threaded tube.

a supply hose is put on the rear end of the tube and secured with a metal clamp;
the operating pressure is set on the reducer and gas is supplied;
wait until all the air comes out of the hose, then ignite the gas, bringing it into the flame of the gas burner;
After this you need to sand the end. The flame on the burner should be 5 cm long;
the housing with the divider is put on the external thread of the nozzle. The burner should produce an even flame without soot - to achieve this effect, you need to slowly rotate the body along the threads on the nozzle;
the loose threaded connection is sealed with FUM tape.

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

For installing a soft roof, weld-on materials are considered the best heat and water insulators. This procedure involves the use of a roofing torch. Such work is very complex and time-consuming, but the result can be a very reliable and durable coating. Therefore, for work it is necessary to choose only proven and high-quality equipment.

What is a roof burner

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

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

The roofing gas burner 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 devices that run on diesel fuel can be found on sale. The substance enters the device through a gas pipeline. The gas supply and fire intensity are regulated by a special valve located on the body. The built-in gearbox allows you to minimize fuel consumption and control its consumption.

All models of gas burners for roofing work are equipped with an air suction system. This feature is required. Additional options that increase comfort include a choice of operating modes. Eg when the propane roofing torch stops, the standby mode automatically starts, which allows you to save gas. Such equipment is lit with an ordinary lighter or matches.

Types of gas devices

To install bitumen roofing, manual burners are used. They are often “powered” by propane. This equipment is very convenient to use, and the flame length is adjusted using a simple lever mechanism . Considered the safest gas-air roofing burners.

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

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

Compliance with safety 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:

Equipment manufacturers and their costs

Today on the Russian market you can find different types of roofing burners, both foreign and domestic. Consumers speak positively about equipment from the Kalibr and Donmet brands. The products of these companies are characterized by high safety and excellent quality. Typically, these are cheap devices that are only suitable for minor roofing 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 simple repairs, it is best to purchase a model that costs up to 1000 rubles. Within 700-900 rubles you can get very good products. High-cost products are characterized by greater 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-production of the device

A roofing material burner is a very complicated device. To make such a device yourself, you will need to study a large number of rules and have some skills. One way or another, it is better to entrust some of the work to professionals. This refers to the fuel storage vessel and its supply system.

A divider and a metal rod are used as a torch. The handle should be made of heat-resistant wood. The wire supplying the gas can be made from brass yourself or borrowed from a welding system.

You need to work with homemade equipment very carefully, checking for malfunctions and fuel leaks. Even if the problem is minor, it is better to stop treating the roof immediately.

To carry out repairs and other roofing work that involves melting mastics and laying roofing materials, you will need a special gas burner. The device is primarily used to perform the following tasks:

Heating and drying of roofing materials;

Metal cutting and soldering;

Firing 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 attached to the body. Heat-resistant plastic or wood can be used to make the handle. Gas enters the housing passing through the gas pipeline. In most cases, propane under pressure is used to operate the burner.

The burner glass should have a shape that protects the flame from being blown out by the wind.

There is a valve on the burner body that allows you to adjust the flame length and the intensity of the supplied gas. It’s good if the burner has a reducer, which allows you to use gas economically.

Roof burner components

During the assembly process of the device, mechanical processing is practically not used. The burner is assembled from ready-made spare parts. To make it we will need:

A steel valve that can be taken from a cylinder intended for storing liquefied gas.
A plug used for transporting gas cylinders.
A nozzle 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.

You can use the handle from a burnt-out soldering iron as a handle.

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 secure it with glue. The divider and body must be machined from a brass rod, the diameter of which should be 20 mm. In the finished body, two radial holes are drilled (each diameter is 5 mm) and four holes are drilled in the divider rod (each diameter is 1 mm).

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

Such nozzles are found 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. doesn't reach the exit. Drill with a diameter of 0.4 mm. used for jumper. The resulting hole must be completely caulked with gentle hammer blows. Then you need to sharpen the end. To do this, take sanding paper and sharpen it until the desired cross-section of the outlet hole is found, that is, until the nozzle can be placed on the tip of the threaded burner tube.

A supply hose made of fabric-rubber material must be attached to the end of the gas supply tube. Secure the hose to the tube with a clamp. We set the operating pressure, after which we supply gas. Wait until all the air is forced out of the hose, and only then insert the nozzle into the flame of the gas burner.

Attention! The nozzle is introduced into the flame without a housing or a divider.

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

To achieve the desired effect, slowly rotate the body on the nozzle thread.

If you have a loose threaded connection, seal it with FUM tape.

Video. How does a roofing gas burner work?

Hello! My name is Viktor Kaploukhoy. I am an engineer by training, graduated from a technical university. Hobbies: IT, engineering and technology.

In just two decades, construction technologies have been updated, new building materials and tools have appeared. For example, the old faithful roofing felt has given way to new fused roofing materials, which are better in all respects. No one will argue with this anymore. And accordingly, the bucket with hot bitumen and a brush for coating has gone into oblivion, instead of which builders today use a gas burner for roofing work.

What is a gas burner

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

An injector, inside of which a nozzle 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 flammable gas is mixed with air (oxygen). The glass has many holes through which air is sucked into the flame zone. In addition, this device protects the fire flame 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 holds.
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 reduces the gas pressure in the line. The gas pressure at the burner outlet is 0.1-0.15 MPa. A 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 it.

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 assemble the nozzle and glass. The remaining elements and parts are ready-made units and parts that are sold in any hardware store. Therefore, it will not be difficult to make it yourself.

So, what is required to assemble a 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 in 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 towards the center. You will get a cone, but you don’t need to bring the petals all the way down; you need to leave room for the main tube, onto which the glass is placed. After which the petals are pressed against the tube, where they are sealed. There are slots between the petals that will serve as air supply 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.

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

A gas control valve is screwed into it. The second connection, it is double-sided, is screwed into the valve on the other side. Be sure to wrap it on a sealing material. For example, on fum tape. An adapter from a threaded connection to a hose connection is screwed onto the rear end of the second bend. There is no point in making it yourself, because it is sold in any hardware store and is very cheap.

Now all that remains is to make the handle and install it on the prepared device. There are a huge number of options for handles. The main thing here is to hold the entire homemade device comfortably. For example, it can be cut from a wooden board 5 mm thick, you can buy an ax handle and adjust it to the size and shape. It is better to attach the handle to the brackets, because this is the strongest section in the entire structure. Optimally, this is a rear drive, because the control valve should be located slightly in front for ease of use.

There are different ways to attach a piece of wood to a metal tube.

Make a recess along the entire width to match the diameter of the pipe of the squeegee, place the squeegee in it and secure it with two clamps made of metal tape.
Install the squeegee on the side of the handle and also secure with clamps.

So, you have made your own gas burner for roofing work; 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 secured with a clamp. Its second end is threaded into the adapter, where it is also secured with a clamp.

The cylinder opens, the supply of propane through the gas reducer opens. And the last thing to open is the control valve on the injector. Gas should flow through the nozzle with a characteristic sound. You must wait until the air inside the device is completely released. After which the gas flow is ignited. The valve near the handle regulates the length and power of the torch.

Attention! A homemade gas burner for roofing work is a high-risk device. Therefore, all operations performed must be approached with special care. This is especially true for the connections of all elements with each other. Complete tightness must be maintained.

Fire safety measures

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

Keep a fire extinguisher on the roof when performing roofing work.
All work is carried out only during daylight hours.
When laying a soft roof using a gas burner, only one propane cylinder can be placed on the roof.
It must be avoided from heating up.
The roofing material itself must not be overheated or ignited.

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

Roof microburner– this is a movable structure with comfortable handles for carrying. The Sympathy contains a small weight, up to 1.5 kilograms, and is equipped with a handle made from a log or plastic that is comfortable for use, up to 1 m long.

In the gas property, the only thing used is hydrocarbon. Someone acts in the shell using a gas hose. Its supply and length of fire are regulated with the support of a special valve in the burner. In order to save exhausted gas, roofing games are equipped with a gearbox, which controls fuel consumption.

Absolutely all gas burner systems take into account the concept of atmospheric suction. This is an inevitable role, but it is also necessary to accept auxiliary ones, which provide the service in the most convenient way.

In the main priority is the possibility of coordinating workers' regimes. For example, if there is a stop in the service, the order of hope is introduced and fuel is saved. Each gas microburner lights up with ordinary matches or a lighter.

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

What kind of equipment is this?

The structure of the burner includes an owner with gas supply regulators, which makes a railroad with a mixer at the end. The microburner is connected with a rubber sleeve to the hydrocarbon-slide gas cylinder using a pressure regulator.

Basically, tamed gas games are used to heat the surface and fuse various substances. Gas games come in two types: forced and non-forced atmosphere.

These types of burners have the following characteristic industrial properties:

Atmosphere supply in a gas burner with forced supply performed in the following way, air is supplied with the support of a propeller or compressor. The advantage of this type of game is the likelihood of a clear torch option. The downside is the difficulty of installing the device.
In burners that do not have a forced supply of atmosphere, air is supplied freely through a hole in the diffuser due to the number of gas supplies. The simple structure makes it possible to do it yourself. The disadvantages include the inadmissibility of a clear torch option.
The gas microburner is started by igniting a gas stream, which is obtained from the diffuser; in some modifications, automatic ignition is taken into account.

Design and principle of operation of the burner

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

A metal cup with convex holes along the sides.
A nozzle for the purpose of spraying gas.
Plastic or wooden owner.
Rubber sleeve with the purpose of gas cart to the body of the game.
Valve for regulating the supplied gas and the length of the fire.

Due to the modification, the game has the following differences:

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 due to its installation is from 0.8 to 1 meter and the weight is approximately 1.5 kg. In addition, due to the modification, gas games have every chance of being equipped with different fuel saving modes.

Roof burner models

For work related to laying the roof, a specified type of device with the following modifications is used:

GG-2 propane micro-burner for the purpose of preparing and performing waterproofing work. Excellent for small-scale roofing work. Recommended for use by young professionals. Mostly low price.
GG-2U The similarity of the previous modification is distinguished by the curly gas route. It is mainly used in inaccessible areas near the roof.

Heat performance.
Weight and length.

Application of gas burners

For the purpose of repair work and the adaptation of roofing with bituminous substances, a gas burner is preferably used. Due to 8 hours of labor time, approximately 600 square meters of welding material can be placed next to a high-quality burner.

Work on the installation and repair of various types of roofs using gas must be carried out in accordance with absolutely all fire protection laws.

For work on laying different areas of the roof using gas, accept established limits such as:

You can only lay no more than 500 square meters at a time.
When laying more than 500 m, the presence of fire hoses with water is necessary.
Has access to fire hydrants and is required to appear at four edges of the mulched roof.
Water supply using a fire hose must be supplied to each point of the laid plane.

Stages of work when laying material using a roofing torch

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

Cleaning the roof surface from debris.
Unwinding the rolls in the plane of the roof with an overlap of at least 10 cm for marking purposes. Subsequently, the rolls must be wound and numbered.
Priming the plane with prime in order to remove microcracks, chips and dust binding.
Having marked the plane and primed it, the rolls are unwound over time and heated with a gas burner in order to fuse it into a plane.
During the final period of laying movement, it is necessary to heat the seams of the deposited substance with a torch.

After fusing the substances, in order to prevent wrinkles, the covered plane must be rolled out with a roller.

How to make a gas burner with your own hands?

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

Rectifier with pressure reducer to regulate gas supply. It can be taken from an oxygen cylinder.
A stopper that is used for transporting gas cylinders.
Liquid fuel nozzle with a nozzle diameter of 0.8 millimeters. It can be taken from a gasoline blowtorch.
A piece of an iron route, a tube version, with a length of only one unit with a diameter of 10 millimeters and a wall width of 2 millimeters.
Handle made of slightly heat-permeable substance. Mostly from a log.
Shell and gas divider game (cup). They can be turned from a brass rod with a diameter of 20 millimeters.

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

The road is inserted into the made handle and secured with glue.
In the turned body it is necessary to drill 2 radial holes with a diameter of 5 millimeters. In addition, in the housing it is necessary to drill 4 holes with a diameter of 1 millimeter in the divider rod.
The next step in the game production is simply sketching the cutting rod into the shell. The completed shell must be fixed into the railway.
In the routes with the inserted housing, it is necessary to cut the thread with a tap and screw in the nozzle.
At a different route end, a gas-air hose is connected and secured with a clamp.

After installing the gas game, you need to unscrew a certain oxygen rectifier and wait until the blue fuel squeezes out the air space in the sleeve. Then use matches to burn the flow of gas from the body (glass).

Safety rules when working with gas burners for roofing

When operating a gas burner, strict compliance with the security laws is necessary:

Before starting the activity with the device, it is necessary to carry out an inspection of the game into the object of automatic defects and loss. ant. gas income. Micro burner for roofing work
The arson game cannot be played by standing in front of the glass nozzle.
Work must be carried out using canvas gloves, overalls and shoes.
When working with a gas burner, you must be careful not to overheat the raw material being welded. Thus (as well as overheating can cause destruction of the substance.
At the workplace where the microburner is used, there is no need for third-party objects, especially flammable ones.
When working with a gas burner, fire extinguishing resources must be available near the laying area.
The repairman operating with the device is in no way obliged to move with the burnt burner anywhere other than the mulched surface.

The principles of safety during operations with a gas burner must always be observed and indisputably oh, thus it is also a guarantee of the unity of the functioning Person and the people around him.

A gas microburner seems to be a necessary assistant for laying the roof with gentle substances. Such a device, as well as a gas microburner, is widely used in construction and correctional work.

As a rule, gas flames are used for the purpose of fusing roofing materials, removing color from various surfaces, welding and soldering various metals. The game adopts different types of systems for the purpose of different types of works.

It should immediately be noted that it is much easier and more harmless to purchase a finished burner than to make it yourself. However, if you have confidence in your own abilities and always do it with your own hands, then you can try it.

Gas micro burner- this is a difficult apparatus and for this purpose, in order to produce it, some skills will be needed, and the detailed implementation of a large number of laws. However, it is always better to preserve the activity element for the purpose of specialists. This primarily concerns the organization of supply and containers in order to preserve gas.

To produce a torch, a metal base and a gas divider are used. Attach them to the handle from a heat-resistant log.

The hose for supplying gas is drawn from a gas welding organization or personally ground from brass.

Despite the fact that in appearance a roofing micro-burner selected with its own hands differs quite significantly from its shop counterparts, it will manage its main functions.

But next to the service, it is necessary to especially carefully concentrate interest in the smallest gas leaks or other problems. And even on a number of minor issues, the service must be interrupted immediately. Roofing information works in low fuel conditions.

They are especially important for operating near extreme temperatures; in this case, they are equipped with integrated fuel heating. They are fully automated and ready to work with gasoline of different properties.

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

Low-fuel burners stand out from their gas counterparts. In a diesel engine, the fuel enters the chamber under great pressure, which leads to water splashing. And the previously sprayed fine particles are ignited at the exit from the nozzle, forming a fire.

In conjunction with this, the microburner is connected to a compressor and a container with gasoline next to the support of oil-gasoline-resistant hoses.

In a home workshop or garage, there is often a need to use a high-temperature burner. It has the widest range of applications – from soldering to roof repairs. Not to mention the need to heat up the metal part for processing.

When doing metalworking work, a gas torch can be used to 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 area of the future weld.

Tool stores sell a variety of tools for working safely 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 replicated 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 devices for working with fire carry potential dangers. Therefore, a propane torch 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 configured burner can produce up to 1000 ° C, so the nozzle must match the flame temperature;
It is important to choose a reliable working crane. If something goes wrong, the gas supply is first cut off and the danger is eliminated. If the tap leaks, you will not be able to quickly extinguish the flame;
The connection to the gas source (a bottle with a valve or a 5 liter propane bottle with a reducer) must be reliable. It is when operating low-quality shut-off valves that most accidents occur.

Let's consider a typical diagram and principle of operation of an injection burner:

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

The shut-off valve is located on the cylinder valve. Its function is only to open/close the fuel supply; other adjustments are made using a working tap.

The gas supply tube (3) leads the jet into the nozzle and ends with a nipple (6), which 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 a tube and nipple is fixed in the nozzle with a screw. As a rule, the burner is dismountable for cleaning and maintenance of the nipple.

The formed air-gas mixture is directed to the nozzle of the nozzle (8), where the mixture is additionally saturated with oxygen from the air. For combustion stability, ventilation holes (7) are provided.

The burner is made by hand according to the drawing.

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

We will tell you about the structure of the liner separately; the dimensions are shown in the drawing:

The outer diameter of the liner tube (1) should be half a millimeter smaller 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 peculiarity of the design is that by moving the tab inside the nozzle, you can regulate the air leak through the ventilation holes. This allows you to regulate the flame temperature over a wide range.

The nozzle can be made from a steel pipe, but it would be better to turn it from a steel blank on a lathe. The shape of the nozzle should be somewhat narrowed at the outlet, then the flame will be forced and the temperature in the combustion zone will be higher. Alloy steel grade 45 is used.

There are two ways to make an insert: You can assemble it from two tubes and a steel washer with holes. The structure is soldered with refractory solder, with abundant fluxing. Or you can grind 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 primus stove, or a gas burner from a household stove.

Important! When using a stove nipple, remember that the kit comes with different nozzles. For natural or liquefied gas.

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

The burner is set to use the gas that will subsequently be used. The insert is lightly secured with a screw so that the ventilation holes are blocked by half.

By slightly opening the operating valve and moving the insert, we achieve an even, powerful flame. Then we finally fix it in the nozzle.

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

Let's move from theory to practice. How to make a gas burner using available materials:

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

We cut a “rose” in the back part, bringing the ends to the center. A feed tube will be inserted into this bundle.

The part came from a construction foam gun.
This is a device for reusable use, so the steel is strong and coated with refractory chromium.

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

At the end of the gun tube there is a nozzle 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 using semi-automatic welding.

To connect the structure to the working faucet, conventional plumbing fittings with threads were used. This is a simple water pipe; no special steel is needed. The part of the burner where the valve is located does not heat up to critical temperatures. I had to buy a ball gas valve;
The holder is literally made from scrap metal. Handle from a motorcycle footrest. By lightly processing it with a grinder, we get the optimal shape. The clamp for attaching to the burner pipe is from the handlebars of the same motorcycle.

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

It took one weekend to make and 100-120 rubles to buy a tap and a fitting for connecting to a hose.

As a bonus, look at the drawing of the tested miniature device:

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

Conclusion! A homemade gas burner is a reality. Just be careful when operating!
