Propane burner device

Before proceeding with the independent production of a gas burner, it is worthwhile to understand its design features and the principle of operation.

Typically, a propane burner consists of the following elements:

housing;
lever;
distribution nozzle;
gas hose;
gas pipe;
propane tank;
gearbox;
clamps for fastening.

Propane is supplied through a hose from a cylinder under pressure. The volume of gas is regulated by a working valve on the cylinder, but for safety reasons it is worthwhile to additionally install a reduction gear.

These are the main elements that will be present in a home-made device. But depending on the chosen modification, the design may vary slightly

A shut-off valve is used to open / close the gas supply. It is located behind the main valve. Adjustment of the flame intensity is carried out using a working crane.

At one end of the gas hose through which gas is supplied, a special nozzle is attached, at the end of which a nipple is located. The nipple, together with the gas tube, is placed in a metal cup, where, in fact, the creation of a combustible mixture takes place.

Further, the combustible mixture through the nozzle under pressure enters the combustion region.To maintain a uniform combustion process, holes are specially provided in the nozzle.

Having familiarized yourself with the design features of the device, you can begin to create a gas burner with your own hands, especially since it is not as difficult as it might seem at first glance.

DIY instructions

Next, we will talk about several options for homemade propane burners that you can do yourself. In order to build the simplest burner it will not take a lot of strength and skills, but you will have to work harder to create the other two options.

Option 1 - the simplest burner from a piece of pipe

To build such a burner will require very little time and effort. But the process of creating a homemade product must be approached with all responsibility, because you will have to work with an explosive substance and any error in the design of the device can lead to sad consequences.

Using such a device, it is possible to heat metal blanks for forging or heat them up before welding, and it is also possible to repair bitumen roofs. For the owner of a private house, such home-made work in the household will certainly not be superfluous.

Properly made propane burner will last a long time. With it, you can perform many household tasks, without using a number of expensive tools

To make a homemade gas burner you will need the following tools and materials:

two pieces of pipe of different diameters;
fitting;
gas hose;
gearbox;
propane tank;
welding machine;
Bulgarian.

Having prepared all the tools and materials, you can proceed with the assembly of the propane burner. But before that, we recommend that you read the rules safe work with grinder.

It is necessary to take a pipe with a diameter of 40 mm and use a grinder to cut a piece of the desired length from it

Next, the uneven edges of the sections on the pipe must be sanded. To align the edges inside the workpiece, you can use a file, and to grind the outer edge, a grinder is well suited

We find a pipe of a slightly smaller diameter than our billet and weld a fitting to it using gas welding

The next thing to do is to weld the opposite hole in the pipe with a fitting, grind it and drill a hole with a diameter of 0.9 mm

In order to check the performance of a homemade product, do not immediately weld it tightly. It is better to weld three metal rods, check the work, and only then weld completely

We connect the device assembled in the “draft version” to the gas cylinder and check its operability. If everything is in order - you can proceed to the final assembly

After making sure that the burner is working properly, you can remove the metal rods, weld together its parts and paint the fixture with heat-resistant paint

After the paint has dried, you can proceed to the final assembly of the device and connecting it to the propane cylinder. For your own safety, connect the burner only through the gearbox.

Step 1 - cut off a piece of pipe for the burner

Step 2 - grind the resulting workpiece

Step 3 - connect the fitting to the pipe

Step 4 - weld the back of the tube

Step 5 - assemble the device

Step 6 - checking burner performance

Step 7 - assembly and painting of the product

Step 8 - connecting the burner to the cylinder

As you can see, there is nothing complicated in self-assembly of a gas burner. After studying the instructions and having at hand the necessary set of tools and materials, the assembly of the device will take no more than an hour.

Option 2 - a powerful gas burner

We also suggest trying to assemble a more complex structurally, but also a more powerful burner.

To build this option you will need a little more tools and materials, but the result will not disappoint you.

Such a propane burner can be used, for example, for melting metal in a furnace, for burning weeds in its own area, as well as for other purposes.

So, for the construction of a propane burner, you need to prepare the following materials:

couplings - 1/2 ”and 1/4”;
threaded barrel - 1/2 ”and 1/8”;
a plug with a female thread - 1/8 ";
the foot - 1/4 ”* 1/8”;
nipple - 1/2 ”;
quick coupling for low pressure gas equipment;
propane flow regulator - 0.068-0.34 atmospheres;
thread sealant;
a metal sheet;
self-tapping screws;
drills - 6.4 mm and 0.8 mm.

Preference is best given to brass products. In addition, to design a homemade product you will need the following set of tools: adjustable wrench, drill, punch, solder and flux, blowtorch.

Having prepared everything you need, you can start assembling the device.

To begin with, we will drill a hole with a diameter of 0.8 mm in a brass plug. And then, on a steel pipe near the end of the thread line with a 3.2 mm drill, we drill 4 more holes

We solder the brass barrel into the nipple, and in turn, screw the nipple into the coupling. Next, attach the sleeve to the end of the metal tip. To enhance the reliability of the joints, use thread sealant

We connect the brass plug with a drilled hole with a threaded barrel and twist the connection until it stops. We screw the received part into the coupling

Cut a piece of metal sheet of the required size, form a cone out of it. Next, we fasten the cone with screws to the end of the metal pipe

We connect the steel pipe with a brass sleeve. We twist the brass coupling on the other side of the nozzle assembly. And then, screw the foot into the brass sleeve. At the end, a quick coupling for low pressure gas equipment is installed.

Having assembled the device, you can connect it to a gas cylinder with propane. For this, the gas supply regulator is connected to the cylinder, and the quick-disconnect gas connection to the burner

After connecting all the parts, it is imperative to check all joints for gas leakage. The easiest way is to lubricate the compounds with soapy foam. If bubbles begin to appear, the connections are not tight

If no leaks are detected, you can start testing and operating the propane gas burner

Step 1 - Drill gas holes

Step 2 - Assembling the Nipple Assembly

Step 3 - Assembling the nozzle assembly

Step 4 - Making the Burner Nozzle

Step 5 - Connect the received parts

Step 6 - Connect the burner to the cylinder

Step 7 - Check for gas leaks

Step 8 - Testing the Assembled Burner

During operation, do not forget that propane is an explosive gas, and any non-compliance with safety regulations can lead to irreversible consequences.

Therefore, before testing the device, it is imperative to check all connections for leaks. And only after making sure that there is no leak, you can begin to work with homemade.

Option 3 - Miniature Burner Model

Let's look at another version of a propane-fired gas burner. This miniature gas burner is often called the Bunsen burner.

A feature of this device is that it can be freely held in hands without fear of getting a burn. Let's try to assemble it with our own hands.

For work you will need:

Old gas burner.
Thin copper pipe 10 meters.
Copper wire.
Needle with a medical syringe.
Bolt number 8.

Having prepared all the necessary materials, you can begin to create our homemade product.

To do this, use the following instruction:

To create a burner, you can take a copper pipe, for example, from an air conditioner with a diameter of 8 mm, a length of 10 cm. Having cut off a piece of the required length, it needs to be cleared of nicks on the inside and outside. We also saw off a piece of a smaller diameter tube about 4 cm long

To create a burner nozzle, it is necessary to cut a piece of needle from a medical syringe. The edges of the needle when biting can be taken, so we recommend that you clean them with a file, and then walk with a thin wire

The end of the copper tube must be squeezed with pliers so as to fix the needle. Next, you need to process the end of the tube with phosphoric acid, solder a piece of thick copper wire and solder the gap in the tube

If you treated the copper tube with phosphoric acid, you need to wash these places with plain water to avoid oxidation. Next, solder the end of the copper tube as shown in the photo

To simplify the adjustment of the flame, you can use the M8 bolt. To do this, drill a bolt hole at the beginning of a thick copper tube

Using a bolt, you can adjust the intensity of the flame. For reliability, it is possible to strengthen the connection with a metal nut

In order not to hold the burner in your hands, you can make a stand for it. To do this, you need to make two loops of wire on the burner and make a tripod for the burner. To make a tripod you need to take a small piece of thick plywood, drill a hole from the edge and insert a piece of thick copper wire into it. Burner stand ready

An assembled burner with a fully screwed-in bolt gives a minimum flame, and if you open the air supply, the flame can burn with greater intensity. Without fear of getting burned, you can take the burner in your hands

Stage 1 - preparing the tube for the burner

Stage 2 - make a nozzle from a medical needle

Stage 3 - connect the tube to the wire

Stage 4 - we connect two pieces of a copper tube

Stage 5 - insert the adjustment bolt

Stage 6 - test device adjustment

Stage 7 - make a tripod for the burner

Stage 8 - check the device’s performance

Now you know how to build a gas burner with your own hands and what it will take. As you can see, there is nothing complicated in this, it is enough to follow the rules for safe operation of the equipment, which we will talk about a bit below.

Rules for the safe operation of equipment

Gas cylinder equipment, if used improperly, can cause a major explosion or fire.

When carrying out welding work, it is definitely worth using personal protective equipment: glasses, gloves, special shoes.

Before starting work, you need to carefully inspect the equipment for damage. If equipment is dirty, be sure to remove dirt.

You can work with propane cylinders only in well-ventilated rooms, while the air temperature should not be lower than 0 ° С.

Absolutely forbidden:

Work near open flames.
Keep the container tilted when working.
Place vessels under the sun.
Carry out work without gear.
Heat the gearbox over an open flame.

In addition, if you smell gas, you must immediately stop working and close the valve on the cylinder. We also recommend that you familiarize yourself with the main causes of the explosion of cylinders with gas.

Working without personal protective equipment, you can get a burn, not only from open fire, but also from accidental contact with hot parts.

If the considered home-made burners do not suit you, we recommend that you familiarize yourself with other options for manufacturing useful home-made burners discussed in our articles, - blowtorch torch and burner for a bath stove.
