Propane burner device

Before you start making your own gas burner, you should understand its design features and operating principle.

Typically, a propane torch consists of the following elements:

frame;
lever;
distribution nozzle;
gas hose;
gas tube;
propane tank;
gearbox;
clamps for fastening.

Propane is supplied through a hose from a pressure cylinder. The volume of gas is regulated by the operating valve on the cylinder, but for safety reasons it is worth additionally installing a reduction gear.

These are the main elements that will be present in a homemade 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. The flame intensity is adjusted using a working tap.

At one end of the gas hose through which gas is supplied, a special nozzle is attached, at the end of which there is a nipple. The nipple together with the gas tube are placed in a metal glass, where the flammable mixture is actually created.

Next, the combustible mixture enters the combustion area through a nozzle under pressure. 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 make with your own hands. In order to build a simple burner, you won’t need a lot of effort and skill, but creating the other two options will require you to work harder.

Option 1 - the simplest burner made from a piece of pipe

Building 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 dire consequences.

Using such a device, you can heat metal blanks for forging or warm them up before welding, and you can also repair bitumen roofing. The owner of a private house will definitely not find such a homemade product superfluous.

A properly made propane burner will last a long time. With its help 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;
union;
gas hose;
gearbox;
propane tank;
welding machine;
Bulgarian.

Having prepared all the tools and materials, you can begin assembling the propane burner. But before that, we recommend that you read the rules safe work with an angle grinder.

You need to take a pipe with a diameter of 40 mm and, using a grinder, cut a piece of it to the required length

Next, the uneven edges of the cuts on the pipe need to be sanded. A file can be used to straighten the edges inside the workpiece, and a sander works well for sanding the outer edge

We find a pipe with a slightly smaller diameter than our workpiece and use gas welding to weld a fitting to it

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

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

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

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

After the paint has dried, you can begin final assembly of the device and connecting it to a propane tank. For your own safety, you should connect the burner only through a reducer

Step 1 - cut 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 – assembling the device

Step 6 - checking burner functionality

Step 7 – assembly and painting of the product

Step 8 - connecting the burner to the cylinder

As you can see, there is nothing complicated about assembling a gas burner yourself. Having studied the instructions and having the necessary set of tools and materials at hand, assembling the device will take no more than an hour.

Option 2 - powerful gas burner

We also suggest trying to assemble a more structurally complex, but also 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 forge, for burning weeds in your own area, as well as for other purposes

So, to build a propane burner you will need to prepare the following materials:

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

It is better to give preference to brass products.In addition, to construct a homemade product you will need the following set of tools: an adjustable wrench, a drill, a punch, solder and flux, a blowtorch.

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

First, let's drill a hole with a diameter of 0.8 mm in the brass plug. And then, on the steel pipe near the end of the thread line, use a 3.2 mm drill to drill 4 more holes

We solder the brass barrel into the nipple, and the nipple, in turn, screws into the coupling. Next, attach the coupling to the end of the metal tip. To enhance the reliability of connections, you need to use thread sealant

We connect the brass plug with the drilled hole to the threaded barrel and tighten the connection until it stops. Screw the resulting part into the coupling

We cut a piece of metal sheet of the required size and form a cone out of it. Next, we attach the cone with self-tapping screws to the end of the metal pipe

We connect the steel pipe with a brass coupling. We tighten the brass coupling on the other side of the jet assembly. And, then, we screw the fitting into the brass coupling. At the end, a quick-release connection for low-pressure gas equipment is installed

After assembling the device, you can connect it to a propane gas cylinder. To do this, the gas supply regulator is connected to the cylinder, and the quick-release gas connection to the burner

After connecting all the parts, be sure to check all joints for gas leaks. The easiest way is to lubricate the joints with soap suds. If bubbles begin to appear, the connections are not tight.

If no leaks are found, you can begin testing and operating the propane gas burner.

Step 1 - Drill holes for gas passage

Step 2 - Assembling the nipple assembly

Step 3 - Assembling the jet assembly

Step 4 - Making the Burner Nozzle

Step 5 - Connecting the resulting parts

Step 6 - Connect the burner to the cylinder

Step 7 - Check for gas leaks

Step 8 - Testing the assembled burner

During work, do not forget that propane is an explosive gas, and any failure to comply with safety regulations can lead to irreversible consequences.

Therefore, before testing the device, it is necessary to check all connections for leaks. And only after making sure that there is no leak, you can start working with your homemade product.

Option 3 - miniature burner model

Let's look at another option for a gas burner that runs on propane. This miniature gas burner is often called a Bunsen burner.

The peculiarity of this device is that you can hold it freely in your hands without fear of getting burned. Let's try to assemble it with our own hands.

To work you will need:

Old gas burner.
Thin copper tube 10 meters.
Copper wire.
Needle from a medical syringe.
Bolt No. 8.

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

To do this, we will use the following instructions:

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

To create a burner nozzle, you need to cut a piece of needle from a medical syringe. The edges of the needle may become dented when bitten, so we recommend that you clean them with a file and then go through them with a thin wire

The end of the copper tube must be compressed with pliers so as to fix the needle. Next, you need to treat 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 areas with plain water to avoid oxidation. Next, solder the end of the copper tube as shown in the photo

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

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

To avoid holding the burner in your hands, you can make a stand for it. To do this, you will need to make two wire loops on the burner and make a stand for the burner. To make a tripod you need to take a small piece of thick plywood, drill a hole at the edge and insert a piece of thick copper wire into it. The burner stand is ready

The assembled burner with the bolt fully tightened gives a minimum flame, and if the air supply is opened, the flame can burn with greater intensity. Without fear of getting burned, you can take the burner in your hands

Stage 1 - preparing the burner tube

Stage 2 – making a nozzle from a medical needle

Stage 3 – connect the tube to the wire

Stage 4 – connect two pieces of copper tube

Stage 5 - insert the adjusting bolt

Stage 6 – testing the device adjustment

Stage 7 – making a stand for the burner

Stage 8 – check the functionality of the device

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

Rules for safe operation of equipment

If used incorrectly, gas cylinder equipment can become a source of a strong explosion or fire.

When performing welding work, you should definitely use personal protective equipment: glasses, gloves, special shoes.

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

You can work with propane cylinders only in well-ventilated areas, and the air temperature should not be below 0 °C.

Absolutely forbidden:

Work near open flames.
Keep the cylinder tilted when working.
Place the vessels in the sun.
Carry out work without a gearbox.
Heat the gearbox over an open fire.

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

When working without personal protective equipment, you can get burned, not only from an open flame, but also from accidentally touching hot parts.

If the homemade burners discussed above are not suitable for you, we recommend that you familiarize yourself with other options for making useful homemade products discussed in our articles - blowtorch burner And burner for sauna stove.
