- there is no need to spend time on lighting the fire, and the cauldron, placed on the burner, heats quickly and evenly
- absence of soot, smoke and smokes;
- operation stability at low temperatures.
However, any product has its disadvantages. the cost of burners is sometimes quite high.
Options
It is possible to arrange for it and a variant on gas, that is, to create a burner on this fuel. This option is much more convenient, because it is easier to control the flame, there is no need to use wood and wait for a large fire.
It is also important to buy the right cauldron. It is better to settle for a version made of aluminum or cast iron. The first is excellent for hiking. It has compact parameters and modest weight. The second is better suited for home or cottage conditions. You can also use the steel version at the cottage. The steel in it is heat-resistant and thick.
Even before you build a burner for your cauldron, you have to know the specifics of your cauldron. The walls of the cauldron are very thick. The bottom is shaped like a ball. Therefore this pot is not stable on flat surfaces. The shape of the cauldron is such that a ring-shaped support is delivered especially for it. The cauldron should only be placed on it. It is not recommended to put it on a standard barbecue grate or on an outdoor model of the barbecue.
If you want to please yourself and your friends and relatives with excellent pilaf, then you need the right cooking skills and the right cauldron. You cannot make real pilaf in a container with a flat bottom
A tank with a flat bottom heats up more quickly at the bottom than along the walls. The heating is evenly distributed all over the cauldron.
One more thing to remember: if you have just purchased a cauldron without any cooking operations on it, it needs to be cleaned from machine oil residues. It remains after the production process. The method of its elimination is simple: it is rinsed with warm water, a safe household soap is used. Using modern means for this purpose is prohibited. Because they contain elements that are dangerous to health. And this cauldron has very porous walls and bottom.
Gas burners for cauldrons: types and peculiarities of use
Many people from Russia and other countries know that some dishes get their real taste only when cooked in a cauldron. Pilaf, for example, which is so popular among many nations. The cauldron is a cooking utensil of eastern origin. It has been used for cooking for centuries. Its properties are shown in all their glory only on an open fire.
But building a fire the traditional way, with firewood, takes time and effort. And it is very difficult to control the flame, which can easily spoil the dish you are cooking.
That is why we want to offer you the most flexible modern solution. the gas burner. This simple device provides the necessary heating and allows you to cook food in a cauldron no worse than with wood. Gas burner can be used both in the countryside and outdoors, for example, when camping. In this article, we will tell you about the main features of the gas burner for cauldron, its advantages and disadvantages, and give some recommendations on how to use it correctly.
Particulars of production
The peculiarity of the design is that it is very easy to use, there are no traces of soot and odors during the application of the gas burner. This device is compact and can be used virtually anywhere. The main component of the burner is considered to be a flame valve. You can buy a new part, however, and used, but in working condition will do quite well. The process of making a burner with their own hands begins with the handle, then the body and nozzle are made.
Makes a self-made device only on propane, butane or propane-butane mix. That is the device can work safely only with gaseous saturated hydrocarbons and air.
In order to get a burner that is safe in operation and does not waste fuel, it is necessary to make a rule not to scale and adjust the schemes of the example.
To be fair, it is worth noting that not all gas appliances are calculated according to the laws of gas dynamics. But if the manufacturer changes the dimensions of design details, the Reynolds number of fuel (or suction air) will go beyond the limits specified in the original product. A burner with such “improvisation”, if you give an optimistic forecast, will begin to smoke and will be “greedy”, or even dangerous in operation.
And one more important note concerning the peculiarities of burner manufacturing: it is impossible to increase its capacity above 10 kW. And here is why. With burner efficiency of 95% (which is an excellent indicator for amateurish invention), with the power of the device of 1 kW on its self-heating it takes 50 watts. It is theoretically possible to get burnt on the design, but it is not fraught with explosion. But if the burner is built for 20 kW, 1 kW will be superfluous. Threshold manifestation is expressed by the fact that it is hot, or the design flares up. That is why those burner drawings that are oriented to 7-8 kW are not worth considering.
Classification
There are a variety of gas micro-burners for cauldrons, which differ in the type of fuel used, design, power. Each of them is characterized by a number of features and advantages, which allows the user to choose for himself the best solution.
By design
Cauldron has a wide bottom, so when choosing or independently creating a device, you need to consider these design features. The units are made of a variety of metals. The most durable products are cast-iron micro-burners, resistant to a variety of mechanical damage. In order to ensure the comfortable use of equipment, it is recommended to give preference to variants with piezo ignition and power regulation.
According to the design, there are several varieties of gas burners
- Piled stoves look like a compact gas stove for cauldrons with low weight. Fixtures are installed on the cylinder. No more than 3 liters of cookware can be placed on top.
- With a hose. it is a burner for cauldrons, which is connected to the cylinder with a flexible pipe. Fixture is used for setting pots, which have an impressive weight and dimensions. This is made possible by the presence of massive legs with a wide stance.
- With a horizontal cylinder. these are the most budget-friendly devices, which work with the use of simple collet cylinders.
- Integrated systems. such a burner for the cauldron is characterized by being connected to the cooking vessel as a single unit. The design provides a significant reduction in fuel consumption.
Due to the presence of several varieties of gas burners provides the possibility of selecting the most acceptable and financially affordable option for each tourist.

According to power
According to the power of the devices, they are divided into several types. Micro burners can be:
Special regulator provides optimal power of gas burner. When determining this value, it is advisable to ask in advance what kind of cookware will be used for cooking? The larger the cauldron, the higher the power of the gas burner should be.
According to the type of fuel
Gas unit works on propane, butane, isobutane. Connects to the cylinder by means of a threaded fixture. According to the type of fuel burners are
- Injection. works thanks to premixed air and gas.
- Underfloor. heating unit is located at the bottom, so the unit operates without additional blowing.
- Atmospheric. before the start of combustion, the media are partially mixed.
- Fuel oil. injection of the media is carried out, which keeps the fuel in a viscous state.
- Blow-off. works with liquid and gaseous fuel.
- Diffuse. gaseous fuels are used.
According to the design of the burner, partial or complete mixing of media can be carried out.
Homemade injection burner
To the homemade burner of standard design, the gas is fed from the cylinder through a special hose, usually it is propane. Reducing regulator is not needed, because the gas flow is regulated by the working valve on the cylinder.
Use the stop cock to open and close the gas supply, and use the work cock to perform other adjustments of the burner. The gas hose, through which gas flows, is connected to a special nozzle with a nipple.
This allows you to set the size and speed of the flame. Both the nipple and the tube are encased in a metal cup. This is where the propane is saturated with oxygen from the incoming air.

Standard scheme of the gas burner. On its basis, you can develop your own design. For ease of repair and operation, it is better to make it easily demountable
From the metal cup, the combustible mixture enters the combustion zone through a nozzle under pressure. For the process to be continuous, there are special holes in the nozzle, acting as additional ventilation.
For self-made will need a drawing of a gas burner for the horn, as well as a set of tools and materials:
- pieces of pipe, hardware;
- Angle grinder;
- Semicircular or round file;
- drilling machine, if not, can be replaced by a drill;
- welding semi-automatic machine;
- Tapping tool, lance, drill, metal brush, hammer, pliers;
- wheels. stripping, cutting;
- Iron sheet thickness of 1,2, 3 mm;
- welding equipment.
The whole work of making a fuel combustion device consists of five steps.
When creating a gas burner, mandatory requirements must be taken into account: safety of gas ignition, stable combustion, safety in case of changes in draft (backfire) and probability of combustible mixture flashover, insensitivity to moisture inside the burner
The first step is to make the diffuser. The starting material for the mixture can be a piece of pipe of a suitable diameter. E.g. a stainless steel muffler or a water pipe.
Along the tube, use an angle grinder to make cuts to the proper length. Stuff a bearing cage with a suitable diameter on the tube. Repeat the process on the other side.
Then a flap wheel is taken and the surface is grinded until it is completely smooth. all existing pores and areas, which are not welded, are welded on and deburred. Deburr inside the part with a round or semi-circular file.
In order to perform the work in an economical mode at relatively low temperatures, the pipe 3 has thin walls, which increases the speed of gases, contributes to their better mixing, prevents the mixture from igniting in the pipe
The next step is to make the mixer and the confuser. The first has the appearance of a tube. It is suitable water pipe with a diameter of about 2 cm and a length of 9 cm. The tube is welded to the diffuser and the air inlet cone is attached to it.
You can cut a blank for it from a sheet of 1.2 mm thick. Then it is bent, the seam is welded, and the finished part is welded to the mixer. At the end make a plane for adjacency of the adjusting washer. By reducing / increasing the gap between the confuser and the washer perform an adjustment of the incoming air flow.
Next, proceed to the construction of the mechanism for supplying the components of the gas-air mixture. At this stage you will need a bolt with a long thread M10. The head is cut off, then a through hole is drilled at the end with a diameter of 5 mm, and an M6 thread is cut.
You can use a welding wire tip from a semi-automatic machine to create the nozzle. Since it has a decent length, it must be cut. There should be approximately 3 to 4 mm left after threading. The remaining part is enough to make one more nozzle.
An washer with an outside diameter of 43 mm is needed for further work. It can be purchased or you can make it yourself from a sheet of metal. Drill a hole with a diameter of 1.2 cm in the center of the washer. A nut M10 is welded to the ready made washer.
In the assembly of the unit screw the nut on the bolt, install the adjustment washer, screw in the gas nozzle. Insert the nozzle flush with the washer by turning the latter. The first screwed nut is placed in the center of the thread
Before you begin to install it, you will need to make a bracket to fix the assembly to the body. It can be cut from sheet metal. Without changing the position of the assembly, put it on the confuser, put the bracket and weld it to the nut and the body. The place of welding is not important, but it is necessary that the structure is rigid.
Adjust the degree of ejection by screwing it in and out. As practice shows, the best result is achieved when the nozzle enters the confuser to a depth of about two mm. Adjust the amount of inlet air by means of the washer.
The final stage is the test. For this, a hose is put on the bolt. Set the pressure at the pressure reducer to 0.2 kg/cm². You can experiment with this value, but remember that at a high gas flow rate, the cylinder, especially the 5-liter capacity, can quickly freeze. In this case a 0.6 mm nozzle is more suitable.
The washer must be closed completely before ignition or a small gap must be left. After igniting the gas, gradually increase the air supply. The flame will become progressively more intense blue and will gradually move away from the burner spout. The peculiarity of work of the burner in the open hearth is that the further strengthening of the air jet separates the flame from the burner, and it fades out.
To avoid this phenomenon, either place a barrier (flame spreader) along the path of the flame, or use the burner in a closed space. In this case, the fire from the nozzle will ignite the gas and the combustion will be maintained.
The injection burner is inserted into the burner through the hole in the wall of the insulated tank. Forced extraction is an important condition for safe operation
If the burner is operated with mains gas, its flame should ideally be a bright blue. When the gas source cylinder filled with propane-butane mixture, the combustible mixture has the appearance of yellow tongues.
This burner is the injection type perfectly works in an enclosed space. If it is well adjusted, it is possible to get temperatures up to 1200⁰. These conditions are suitable for forging file blanks, annealing blades, melting non-ferrous metals.
Feed gas to the burner from a network or cylinder, control the process by the regulator. To check the regulation and pressure, a test run of the gas or gas mixture is performed, and the smell is monitored.
Features
Gas burner for cauldron is a device of small size and weight, which makes it easy to transport. It also allows you to cook food quickly and comfortably.
One of the main features of such a burner is its simple design.
Thanks to this, it can be assembled at home from improvised means. On various Internet resources you will find many detailed instructions on how and what it can be made from.
The maximum power of the burner can reach seven kW. It is fairly easy to care for, but it is recommended to regularly check its performance. And if the burner is equipped with a piezo igniter, you do not need to use matches for this purpose.
Differences in the way the cauldron is installed
Now that we have found out that the gas burner for cauldron is good, let’s try to get acquainted with what the market offers.
A typical cauldron burner from the store
The vast majority of cauldron burners will be like this:
And here “for the cauldron” is a marketing ploy. This is a wok burner.
This does not mean that you will not be able to cook with these burners in a cauldron. There are many examples where, by careful handling of the cauldron, this has worked. It is important to realize that holding the cauldron by the bottom is very unstable and easily leads to a culinary disaster: the cauldron is often filled almost to the brim.
If the burner doesn’t have its own support ring for the cauldron, it is possible to use high metal tripods or tripods. It’s more reliable.
What it is
A gas burner for cauldrons is a special equipment, used for cooking food easily and quickly during camping trips. The device has a simple design that allows you to make it with your own hands. The body consists of a glass, a handle, a holder, a gas hose.
Among other elements. two reducers, one of which is used for fuel supply, nozzle, head, gas cylinder attachment assembly. The power of the burners can be from 2 to 7 kW. It can be installed with or without feet. Units are made of durable metal, which ensures long life.
The gas burner for cauldrons is easy to maintain, but requires periodical checks of its performance. Since the equipment does not create soot, after cooking the dishes are washed easily. Most of the burners are equipped with a piezo igniter, which provides quick ignition of the fire without the use of matches or a lighter.
Thanks to the presence of paint coating is guaranteed resistance to a variety of negative environmental influences.
