Any tourist, fisherman, hunter or just a lover of travel and outdoor recreation away from civilization will find it useful alcohol burner, with which you can cook food or boil water. You can make it yourself from the simplest materials at hand. And this process will take very little time.

How to make a burner with your own hands?

List of materials required for production:

Two tin cans (you can use beer or soda cans);
. cutting object (scissors, knife);
. hammer;
. sharp object (awl, large needle, button);
. sorbitol, brodrikite or sand;
. fuel (ethyl alcohol 96%, any grade);
. fire source;
. screwdriver and screw;
. ruler with felt-tip pen.

1. You need to take two tin cans and make marks 3.5 cm from the bottom with a felt-tip pen. You can use an elastic band.

2. Make 16-20 small holes around the perimeter of one of the cans, using, for example, an awl and a hammer. The holes should be made at the same distance. You need to be careful not to accidentally injure your fingers. The holes should be kept as small as possible. This will help you use fuel more efficiently. And the flame will turn out good and bright.

4. Cut the cans according to the prepared markings, being careful not to bend them. You can use a knife or scissors.

6. The bottom is filled with a filler that absorbs fuel, for example, sorbitol or brodrikite. Sand will also work. Fillers can be purchased at specialty stores for plant growing. The filler is necessary for even fuel consumption.

7. The burner needs to be assembled. An element without holes is inserted into the part of the can with prepared nozzles. The screw should be unscrewed and fuel should be poured into top part until it is 1/4 - 1/2 full (during use, you will determine what volume of alcohol is optimal for boiling the required amount of water). The screw is screwed back.

8. A little fuel is poured into the recess and onto the nozzles, and ignited in the recess at the top. The heat will cause the alcohol to evaporate and burn. The flame will increase as it warms up. You should remember the fire safety rules.

9. The burner is ready to use! Such a burner will always come in handy on a hike when there is nowhere to get wood to start a fire. The burner will help out not only when fishing or hunting. It can also be used at home if the gas suddenly turns off. This type of burner can boil half a liter of water in about seven minutes. This should be enough time to brew delicious tea or steam some instant food.

In this article we will look at how to make a gas torch for soldering with your own hands. This device is often in demand both in private households and for commercial purposes - for individual technical creativity and various types of construction tasks. In particular, gas burners are used for soldering, metalsmithing, forging, roofing, jewelry work, and for other purposes they produce flames whose temperature exceeds 1500°C.

In metalworking, using a gas torch, you can heat a metal workpiece so that in the end it turns out to be sufficiently hardened. When conducting welding work With some metals, the areas of future seams must be heated.

Parameters for making a soldering torch

Firstly, the device must be made of refractory metals. With a properly adjusted burner, temperatures in excess of 1000°C can be achieved.
Secondly, the burner must be equipped with a reliable operating valve, which will shut off the gas supply in the event of a dangerous situation.
Thirdly, you need to use a reliable connection to a tank with a valve or a 5-liter propane tank with a reducer, which will eliminate the risk of accidents.

Shown below typical diagram and the operating principle of an injection gas burner:

Gas flows through the hose (1) under pressure - usually propane. When liquefied gas evaporates in a cylinder, pressure is generated - sufficient to ensure a stable, directed flame. Here a reducer is not needed; the working valve (2) is used to adjust the gas volume.
The jet flows through the supply tube (3) to the nozzle, and to the nipple (6), which sets the direction of the fire, which is located in the liner (5). This liner mixes gas and air. A screw secures the liner in the nozzle. The burner is dismountable, so the nipple can be cleaned.
From the liner, a mixture of air and gas is supplied to the nozzle of the nozzle (8). There, oxygen saturates the mixture even more. With the help of ventilation holes (7) stable combustion is achieved.

With these dimensions, the burner is designed for cylinders up to 5 liters.
Let’s look at how the liner is constructed separately; the drawing shows the dimensions:

The inner diameter of the liner tube (1) should be 0.5 mm smaller compared to the inner diameter of the nozzle. A washer (2) with air holes is welded inside. The sleeve (2) secures the tube with the nipple.

The design differs in that when moving the tab in the nozzle, it is possible to adjust the air suction through the ventilation holes - and, as a result, adjust the fire temperature over a wide range.

Making a gas burner from scrap materials: step by step

List of materials and tools:
drill;
Bulgarian;
hammer;
sandpaper;
brass blanks for the divider nozzle;
thin brass tube with a diameter of 15 mm;
wooden blocks;
vice;
silicone seal or FUM tape;
connection hoses;
valve for adjustment.

How to make a nozzle and handle

First of all we take brass tube and attach a handle to it - for example, from an old burner, or from wooden block, having processed it beforehand. We drill a hole in the block for a brass tube with the appropriate diameter. Having inserted the tube into the timber, we secure it with silicone or epoxy resin.

Important! To make it more convenient to work, we bend the brass tube above the handle at an angle of 45˚.

Next, we proceed to a more labor-intensive and time-consuming stage of work - manufacturing the nozzle. The hole size should preferably be 0.1 mm.

You can use a drill to make a slightly larger hole, and then adjust the edges to 0.1 mm. The hole must have correct form so that the flame is even.

After this, we fix the workpiece in a vice, take a hammer and carefully, in a vertical plane with a “pull” towards the middle of the workpiece, strike the future nozzle. We rotate the product evenly to form an ideal hole.

Then we take sandpaper with fine grain and sand the nozzle head. To connect to the tube, a thread is applied to the back of the product; the elements can also be simply soldered - but in the future, repairing the parts will be more difficult.

Now we connect the device to gas cylinder and set it on fire - the burner is ready for use with your own hands. However, here you can see that to regulate the gas flow, you can only open and close the valve of the gas cylinder, and thus it is very difficult to obtain the desired flame. What can we do?

How to improve flame control

For normal operation our homemade unit we will install a divider and a tap on it. It is better to mount the tap near the handle, at a distance of about 2–4 cm, but it can also be attached to the supply pipe. As an option, take a burner tap from an old autogen or another similar tap that is attached with a thread. To seal the connection, take FUM tape.

The divider is installed on a pipe with a nozzle; it is made of brass, diameter 15 mm. The most the best option is a cylindrical part with a hole for a tube with a nozzle.
If there is none, we do this:
1. Take a brass pipe with a diameter of 35 mm and cut a piece of 100–150 mm.
2. Take a marker, step back from the end and mark 3-5 points, with an equal distance between them.
3. Drill 8–10 mm holes in the pipe, take a grinder and make straight cuts to them.
4. We bend everything to the center and weld it to the burner pipe.

To properly fix the divider, place it in such a way that the nozzle protrudes 2–3 mm from the connection point. Thanks to this device, the flame will be protected from strong winds, and will also be fed by a flow of oxygen and maintain a stable and strong combustion.
We smooth out all welding points with a grinder - this way our unit will have a more presentable appearance. The burner is now ready! We supply gas to it and you can start working.

DIY burner: video

The main element of a gas boiler is the burner. It is around it that all other elements are displayed. Many aspects of the use of the equipment depend on the design of the node. First of all, it is safety and efficiency. Therefore, many people want to make a gas burner for the boiler with their own hands, which will meet all the requirements of the owners. At first glance, this may seem like a complicated process, but in reality it is not.

Types of burners

Many people believe that a burner is simply a nozzle through which gas is supplied. But this is not entirely true. It also mixes air into the fuel. It is important to consider that the product must have a special design that makes the mixture stable.

The device can be of several types, depending on the method of adding oxygen to the gas:

• atmospheric burner;
• ventilator;
• diffusion-kinetic.

Atmospheric

The operating principle of this component is simple: gas passes through an ejector, where its pressure is reduced. In this case, air gets inside due to different atmospheric parameters.

These devices have many advantages:

• simple design;
• compactness;
• quiet operation;
• reasonable cost;
• possibility of refurbishment solid fuel boiler for this equipment - the burner is simply installed in the ash pan chamber.

However, such devices cannot have high power. The fact is that, due to their design, atmospheric heating pads cannot draw in large amounts of oxygen.

Fan

In this type of device, air is supplied to the right quantity by means of a fan. Due to this supply of oxygen, they have many advantages:

1. There are no power restrictions - any amount of gas is provided required quantity air, which is needed for complete combustion without residues.
2. The chamber in which the reaction takes place may be closed. Oxygen enters inside through a special air duct. This allows you to completely prevent combustion products from getting inside the house due to reverse thrust. There is no need to install a separate air duct. For this purpose special coaxial chimneys, which in fact are a pipe located inside another. Smoke is discharged through internal element, and oxygen enters the boiler, passing between the internal and external walls.
3. Human participation during use is minimized, since the equipment has a “smart” configuration function.

This type of burner also has a number of disadvantages:

1. Compared to atmospheric ones, they are noticeably louder.
2. They have a high price.
3. They only work in conjunction with electricity - they must have their own source uninterruptible power supply. Otherwise, they may fail due to voltage drop.

Diffusion-kinetic

Basically, such equipment is found in large heaters industrial purposes. The operating principle is based on both atmospheric and fan heating.

DIY gas burner

Since designing a fan type requires special equipment, let’s consider creating a gas burner for a solid fuel boiler with your own hands. It is best to choose a valve from an oxygen cylinder, standard VK-74. To do this you need:

1. The outlet pipe is additionally equipped with a fitting, which can be connected to the reactor using a hose.
2. A cap with a small hole for connection to the nozzle is installed on the inlet side of the pipe connected to the cylinder. The latter can be taken from blowtorch or slabs.
3. Welded to the cap steel pipe 100 mm long and 2 mm wall thickness.
4. It is imperative to ensure that there is a gap of 15 mm between the cap and the nozzle, through which oxygen will flow. That is why you must first attach three small pieces of wire to the first one (they can then be bent to the desired location), and only then the pipe.
5. The burner itself is ready. After this, you need to make a base on which it will be located for installation in the combustion chamber.

In addition to creating the burner itself, it is also important to follow the process of lighting it:

1. The gas supply valve on the cylinder or line opens.
2. A match is brought to the nozzle.
3. The main valve opens.

Important! The power of the device can be adjusted using a valve. The hottest flame is green-blue.

The whole setup consists of placing the torch in the center. To do this, the wire holders are slightly bent.

Features of use

Gas burners are unpretentious in maintenance. Main feature is an annual cleaning. In this case, the procedure should only be carried out by highly qualified specialists, since this requires disassembling the boiler. Most often, burner cleaning is carried out by a service center.

Dirt can be easily removed using compressed air. It is important to set the appropriate pressure. The fact is that some modern parts may not withstand a flow of 10 atm.

To make the cleaning process faster and less frequently required, a special filter is installed on the gas supply. This is done by the master after submitting an application to the appropriate structure.

Well, despite the fact that a gas burner in a heating boiler seems like a very complex engineering unit, you can still make it yourself without any problems. For this you need to prepare everything necessary materials and have skills in working with metal. In addition, you must have several units of special tools.

In a home workshop or garage, there is often a need to use a gas burner. It has the widest range of applications – from soldering to roof repairs. Not to mention the need to warm up 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 ballpoint pen for jewelry soldering.

Or m new 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 gas burner with your own hands.

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

Drawings and step-by-step instructions for making a burner

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 point to the gas source (a bottle with a valve or a 5 liter propane bottle with a reducer) must be reliable. It is during operation of poor quality shut-off valves most accidents occur.

At home, the need for a burner very often arises. The purpose of such a device is very wide, for example, soldering work or repairs roofing material. Also, in the garage it is often necessary to warm up a part for processing. For plumbing purposes, a gas burner is used for heating metal parts for the purposes of subsequent hardening. Therefore, many craftsmen began to be interested in how to make a gas burner.

Gas burner design

Hardware stores sell large quantities various models gas burners for safe use. For example, popular propane design can be of various modifications, even the size of a regular jewelry pen. The advantages of factory models include a high degree of safety and product certification. But on the other hand, the design is not complicated, and making such an instrument at home will not be difficult. And since any product in the store is not cheap, especially a burner, novice craftsmen can and should learn to make it themselves.

The gas burner device includes the following elements:

• metal body;
• nozzle;
• gearbox;
• fuel supply regulator;
• unit for securing the cylinder;
• head.

The metal body is also equipped with a special glass, with the help of which the fire in the burner will not be blown out. The design includes a metal handle. As an alternative, other materials can be used for it. Its dimensions should not exceed 100 centimeters. A wooden holder is installed on the handle, and then the hose is pulled on. There is also a gearbox with a valve. They can regulate the amount of gas burned, its length and, accordingly, its supply. A similar design is also equipped with a nozzle for igniting gas.

A gas burner is also called a propane burner. This indicates that propane gas is used as fuel or a mixture of propane and butane. A special container or cylinder, which is located behind the burner, is filled with this substance.

Many people are interested in how to make a burner with their own hands. As can be seen from the list, the design of a gas hand burner is not complicated, but on the contrary, it is even very simple for self-production. She doesn't have complex elements, on which you need to spend a lot of money and time. Its production will require a little time and labor. And if you necessarily study all the diagrams and drawings from professionals, and also treat the work responsibly, you will end up with a convenient and safe device.

In practice, a person who has never made similar structures, after half an hour or an hour, understands how to make a burner on his own, and does it.

If we talk about the use of such a burner, it can be different. For example, there is a burner for a boiler, fuel-air design, homemade design from a burner for heating with household gas, etc. They even manage to make a burner from a lighter. This design, of course, is not suitable for performing the functions of a gas cutter, but for some purposes it can be used. There are also burners for copper melting with a built-in nozzle.

Self-assembly of the product

Assembling a propane gas burner with your own hands is the most interesting and exciting stage of the work. For beginners and inexperienced masters, it is necessary to study it as accurately as possible to obtain quality product. It is necessary to take into account all the nuances and advice.

First, you should think about the most interesting thing - the handle of the product. To create it, you can use any material. As an option, a handle from an old soldering iron or other device is perfect. The supply tube must be made of steel only. Other materials will not work.

It is very important at the initial stages to pay attention to the dimensions of all structural elements. For example, the diameter of the supply tube should not be more than 1 centimeter, and the thickness of the steel should be 2-3 millimeters. Such an element must be fixed to the handle using glue or another substance to fasten such parts.

Burner body

The basis of the burner is its body. It is also made of steel, oddly enough. For such purposes, it is better to use a brass rod with a diameter of 2 centimeters. To make a divider, you may also need similar material. After this, several holes should be made so that air can circulate freely inside the product. This is done for everyone known reason- Fire cannot burn without oxygen. As a rule, five or six such holes are required, and their diameter should be one millimeter. They are done in the structure divider itself.

Next you need to mount (push) the divider into the burner body. This will require quite a lot of force. In contrast to the divider, the internal flange should be installed with a small gap of approximately half a centimeter, thereby in the future the huge flow of gas that enters the igniter will be slowed down.

Nozzle device

For homemade lamp You also need to make a jet using propane gas. With the help of such a part, fuel supply is ensured. The fuel is propane, which is in a cylinder. For manufacturing, you should use a metal rod. You need to make a blind hole in it. To do this you need to have a 2 mm drill. The jumper needs to be made with a 4 mm drill. Such holes must be tapped with a hammer and sanded.

Next, a hose from the gearbox is mounted on the end of the tube. It must be made of a special rubber and fabric mixture. Fastening occurs by fixing the hose with a clamp. After the hose is securely fastened, it is necessary to correctly set the pressure in the cylinder and supply gas to it. With the help of such actions, air is completely expelled from the system. If everything is done correctly, then the length of the fire should be at least 40-50 millimeters.

Homemade design is very good tool and a unique tool that will always help a young master in any household situations. And since it is very easy to produce it yourself, the popularity of such a tool is growing every day.

Which gas to choose

Gas burner for do-it-yourself soldering is made exclusively using fuel such as:

• natural gas;
• propane;
• butane;
• propane-butane mixtures.

In other words, on hydrocarbon mixtures with atmospheric air. If you use fuel consisting of 100 percent isobutane, you can get a combustion temperature of 2000 degrees Celsius.

Acetylene is a substance that allows you to get temperatures up to 3000 degrees. But such a device is currently not popular for several reasons: the need for constant oxygen, high level dangers, the need to use expensive calcium carbide for work and other reasons.

It is more than possible to obtain hydrogen at home, and such a device is capable of producing a temperature of 2500 degrees. But the starting materials for producing this substance are also very expensive (the main mixture for production is hydrocyanic acid). Besides, they are unsafe. Another disadvantage of hydrogen is that it can be smelled.

A substance such as methane is not used in household burners for obvious reasons. In addition, the gas is very poisonous. If we talk about methane fumes, they do not produce a large flame when burned, and the average temperature of the structure is 1100 degrees.

How to achieve safety

Those who are interested in the question of how to make a burner at home need to first understand all the safety measures. In order for a homemade design to be effective in operation, it is necessary to constantly follow the prototype drawings and there is no need to make your own changes there.

Very often a situation arises when the flame burns unevenly and smokes heavily. To get rid of this effect, turn the body on the nozzle thread towards you. This should be done until the gas gives a good and desired shade, as well as a stream of fire. If the nozzle thread moves very freely, it must be sealed with tape.

In order for a small mini-gas burner or other home-made structure to be safe to use, it must be checked for leaks before the first start and subsequently from time to time. Particular attention should be paid to solder joints, places where connectors are combined, sleeves, etc. important points. After this, you need to wait, opening the valve a little. You should wait until the flame starts. All stages occur automatically, so there is no need to take additional actions. After this, you just need to adjust the flame level and you can start working.

Thus, the burner is necessary tool in the house for beginners and experienced craftsmen.
