Regardless of the type of gas burners, they are all devices for mixing oxygen and gaseous fuel, which then enters the outlet, providing a steady torch fire. The considered devices are divided into several categories, have a wide range of advantages. Along with ease of use, the element demonstrates fast start-up, heat-up and subsequent operation. The devices in question are used in the arrangement of industrial, domestic boilers and furnaces.
General information
On the modern market, there are two types of gas burners, divided according to the type of supply and formation of the working mixture. One of the options includes an atmospheric-type injection device in its design. The second analogue has a pressurized ventilation system. Injectors are mainly included in heating equipment with the corresponding types of boilers. The version with built-in fan is more suitable for heating as it is more efficient.
Designation of elements:
- Supplying the air-gas mixture to the working source of ignition.
- Mixture formation.
- Ignition site stabilization.
- Support the required intensity of combustion.
Types of gas burners
The following are the main types of equipment in question:
- The diffusion option is a model in which air and fuel are mixed directly during combustion.
- The injector modification is a device in which the components are pre-mixed, while one of the combustion media is sucked into the chamber of the second tank (ejection version).
- Gas burner for oven with full early connection. With such variations, the combustion mixture is supplied ready-made in front of the outlet. Some models produce a short and almost non-luminous flame.
Features
Modifications of the first type include the design of air and gas supply separately. Additionally, the process involves elements responsible for the process of mixture formation. During operation, a filler from gas and air is supplied to the furnace in the form of a turbulent flow with different fields of fuel and oxidizer concentrations in the cross section. After the composition enters the high temperature compartment, it ignites.
Part of the working stream, where the capacity of gas and air is presented in stoichiometric proportions, burns out in a kinetic way. In areas of incomplete formation, this procedure proceeds in a diffuse mode. The combination of fuel components in the furnace is carried out by means of a special device responsible formovement of individual particles and criteria for flowing out of the mixer.
The specifications of the turbulent type gas burner are as follows:
- The mixing of gas and air is carried out by diffusion.
- Since the combination of the components of the composition is the inhibitory part of the overall process, the intensification of operating modes is required. It is achieved by reducing the supply flow by tightening the guide vanes or by introducing the mixture in small doses.
- Scope of the considered burners: heating domestic and industrial boilers.
- The device has a wide range of regulation, which allows you to increase its performance.
- There is a possibility of burning a significant amount of gas with relatively small dimensions.
- Simplicity of design with combined use of coal dust or fuel oil.
- Power rating - 60 kW to 60 MW.
Overview of gas burners
When choosing a device, one should take into account its technical characteristics, type of fuel supply, compatibility with other devices and the principle of operation. Several types of burners are popular among consumers. Let's start the review with a modification of the KChM. Most often, it is operated in boilers converted from solid fuel analogues or LNG. The design is equipped with three nozzles and automation.
The second popular type of gas burners is the Hearth. The device is a pneumatic mechanism with automatic functionality. It has a high levelsecurity and stops working in the following cases:
- With lack of traction.
- If the flame goes out.
- Due to natural gas disruption.
"Hearth" has a fuel pressure controller, which makes it possible to optimize combustion, even in case of failures in the main system. These models are easy to maintain, soot does not accumulate in the convection compartment.
Other analogues
Among other types of gas burners, the following modifications are distinguished:
- "Cooper". This equipment is designed to work with almost any type of coolant. Among the advantages of the model is the possibility of installation without welding and complex metalwork.
- For DKVR boilers. The device is a block mechanism with forced oxygen supply. The specified equipment is used in steam industrial units of the appropriate capacity. The efficiency of the unit is up to 94 percent. The product operates on a diffuse or pressurized principle. Powerful fans enhance efficiency.
- For CWR. These household gas burners are designed to work in solid fuel boilers. Stability of work is provided by atmospheric or injection supply of the mixture. When selecting this modification, special attention should be paid to safety indicators and suitable power.
Ceramic options
Such infrared heaters, as a rule, do not require connection to the main line, they are mobile, working from a cylinderwith liquefied gas. The air is heated by a special radiation.
Ceramic gas burner is not designed for uniform heating of a large room. Despite the local impact, this device has a number of advantages. Firstly, there is no need for a long wait for heat, literally in a minute the treated area warms up to the required temperature. Secondly, the device can be used in open areas (pergola, terrace or porch).
The device of a ceramic gas burner is not difficult. The main element is placed in the metal case, as well as the regulator with the valve system. They are responsible for safety, ensuring that the mechanism is turned off in case of various malfunctions or tipping over. A ceramic infrared panel is responsible for heating, converting the energy of the fuel into radiant heat.
Travel version
Next, consider a portable type of gas burner and the principle of its operation. The device belongs to the ceramic options, ideal for heating the tent during hiking trips. The model is compact and fits into a backpack without any problems. The modification can be used both inside the tent and on the street.
Because the device has a high level of fire danger, it should not be left turned on unattended. Do not remove the grate, dry flammable items or cover during use. The device has a simple design in the form of a spray can and a feed nozzle. Howevermanufacturers categorically do not recommend repairing gas burners or disassembling them on their own, without the participation of a specialist.
Models with piezo ignition
The operation of this device is as simple as possible. The design does not clog, does not require additional heating, eliminates the appearance of unpleasant odors. A gas burner with piezo ignition has a wide range of functions, a modification of this type is especially popular among tourists, hunters, and fishermen. In addition, the device is used for soldering some materials.
Varieties:
- Portable models. They are a design of a cylinder with a fuel mixture and a special nozzle attached to a gas tank or by means of an adapter in the form of a hose. The features of this type include the ability to install dishes of a suitable diameter on the upper part of the body.
- Tabletop versions - horizontal devices with a large cooking surface. The gas cylinder is placed in the body part, fixed with a collet grip. Such modifications can be connected through a special adapter.
- Combination burners. The device is made in the form of nozzles, which are equipped with a small gas reservoir.
Device
The design of a gas burner with piezo ignition includes a nozzle for supplying a flame, a fuel regulator, a piezo element (actuated by a button or a trigger). The modifications under consideration owe their popularity to ease of maintenance and low cost. The simplest option is a dividergas jet with power corrector. The last element is screwed directly onto the cylinder, additionally plays the role of a stand. Among the advantages are compact dimensions, low price, low weight.
There are also more sophisticated burner designs on the market. Such devices include folding legs, a special valve, and are stable. At the same time, they have a large mass and dimensions. More details should be given to the piezo element itself. Many modern stoves are equipped with this mechanism, the main task of which is the automatic ignition of fuel. The advantage of this option is that there is no need to use matches or a lighter. As user reviews show, you should not rely entirely on this option, it is one of the most vulnerable parts of the furnace. However, with proper use, the element will last a long time.
Pros and cons of piezo modifications
The advantages of such models, consumers include the following points:
- Ease of design.
- Reliability.
- Economy.
- Light weight and dimensions for easy storage and transportation.
- Long working life.
- Possibility of cooking and heating food in remote places autonomously.
There are also some disadvantages of these devices, namely:

- Unstable operation at low temperatures.
Subject to allpros and cons, the gas stove burner remains one of the most popular options over electric or solid fuel counterparts.
Safety
Gas appliances should only be operated in well-ventilated areas or rooms equipped with a reliable ventilation system. Keep flammable objects and other sources of ignition away from burners.
Before lighting the burner and during its operation, it is forbidden to direct the flame at parts of the body or things. The cylinder must not be disconnected while the device is in operation. It is necessary to turn off the tank only after the fuel supply to the burner has stopped.
Keep the device out of the reach of children, the recommended temperature range is not higher than 40 degrees. It is recommended to have a fire extinguisher or other fire fighting equipment nearby during operation.
It is worth noting that the preparation for the ignition of the unit should be carried out during the scheduled maintenance of gas appliances. Usually this procedure is performed before the heating season. It is strictly forbidden to operate the burners without first checking them.
Summary
Gas equipment used in the industrial sector and boiler houses is not much different from household counterparts. Among the features are the ability to withstand high pressure and the presence of filters to screen out particles of dust, tar and other waste products. This solution makes it possible to increaseeconomy and technical efficiency of devices.
