Types of gas burners and principles of their work

Regardless of the type of gas burner, all of them are a device for mixing oxygen and gaseous fuel, which then enters the outlet, providing a steady flare. The devices in question are divided into several categories, they have a wide range of advantages. Along with ease of use, the element shows a quick start, heating and subsequent operation. The considered devices are used in the arrangement of industrial, domestic boilers and furnaces.

General information

On the modern market, two types of gas burners are offered, which are divided by the type of supply and formation of the working mixture. One of the options includes an atmospheric type injector device in its design. The second analogue has a supercharged ventilation system. Injectors are mainly included in the heating equipment with the corresponding types of boilers. The version with built-in fan is more suitable for heating, as it is more efficient.

Appointment of elements:

  • The supply of air-gas mixture to the working center of ignition.
  • Mixture formation.
  • Stabilization of the ignition site.
  • Support the required burning intensity.

Types of gas burners

The following are the main types of equipment in question:

  1. The diffusion variant is a model in which air and fuel are mixed directly during combustion.
  2. The injection modification is a device in which the components are mixed beforehand, while one of the combustion media is sucked into the chamber of the second tank (ejection version).
  3. Gas burner for stove with full early mix. For such variations, the combustion mixture is delivered ready-made in front of the outlet. Some models produce a short and almost non-luminous flame.

Features

Modifications of the first type include a separate air and gas supply design. Additionally, the elements involved in the process of mixture formation are involved in the process. During operation, a filler of gas and air is fed into the furnace in the form of a turbulent flow with different fields of fuel and oxidizer concentrations in cross section. After the composition enters the heat compartment, it ignites.

Part of the work flow, where the gas and air capacity is represented in stoichiometric proportions, burns out in a kinetic manner. In areas of incomplete education, this procedure proceeds in a diffuse mode. The combination of fuel components in the furnace is carried out by means of a special device that is responsible for the movement of individual particles and the criteria for the flow exit from the mixer.

The following are the characteristics of a turbulent type gas burner:

  • The mixture of gas and air is diffusion.
  • Since the combination of the components of the composition is an inhibiting part of the overall process, the intensification of operating modes is required. It is achieved by reducing the feed stream by tightening the guide vanes or by supplying the mixture in small doses.
  • Scope of the burners in question: heating of domestic and industrial boilers.
  • The device has a wide range of regulation, which allows to increase its productivity.
  • There is the possibility of burning a significant amount of gas with a relatively small size.
  • Simplicity of construction with combined use of coal dust or fuel oil.
  • Power indicator - from 60 kW to 60 MW.

Overview of gas burners

When choosing a device, its technical characteristics, type of fuel supply, compatibility with other devices and the principle of operation should be taken into account. Several types of burners are popular among consumers. We begin the review with a modification of the KFM. Most often, it is operated in boilers transformed from solid fuel analogues or LNG. The design is equipped with three nozzles and automation.

The second popular type of gas burner is the Hearth. The device is a pneumatic mechanism with automatic functionality. It has a high level of security and stops working in the following cases:

  • With a lack of traction.
  • If the flame goes out.
  • Due to a violation of the supply of natural gas.

The "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 is not collected in the convection compartment.

Other analogues

Among other types of gas burners, the following modifications are distinguished:

  1. "Cooper." This equipment is designed to work with almost any kind of coolant. Among the advantages of the model is the possibility of installation without carrying out welding and complex metalwork.
  2. For boilers DKVR. The device is a block mechanism with forced oxygen supply. The specified equipment is used in steam industrial units of appropriate capacity. The efficiency of the unit is up to 94 percent. The product operates on a diffuse or supercharged principle. Powerful fans allow you to increase work efficiency.
  3. For CWR. These household gas burners are designed to work in solid fuel boilers. Stability of work is provided by atmospheric or injection flow 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 characterized by mobility, working from a cylinder with liquefied gas. Air is heated by special radiation.

Ceramic gas burner is not designed for uniform heating of a large room. Despite the local impact, this device has several advantages. Firstly, there is no need for a long wait for heat, in just a minute the treated zone warms up to the required temperature. Secondly, the device can be used in open areas (gazebo, terrace or porch).

The device of a ceramic gas burner is not difficult. The main element is placed in a metal case, as well as a regulator with a valve system. They are responsible for safety, ensuring the shutdown of the mechanism in case of various malfunctions or tipping. A ceramic infrared panel that converts fuel energy into radiant heat is responsible for heating.

Marching version

Next, we consider the portable form of a gas burner and the principle of its operation. The device belongs to the ceramic options, ideal for heating the tent during hiking. The model is compact, fits into a backpack without any problems. The modification can be operated both inside the tent and on the street.

Since the device has an increased fire hazard level, it should not be left unattended when turned on. During use it is forbidden to remove the grill, dry flammable things or cover. The device has a simple design in the form of a spray can and a feed nozzle. Nevertheless, manufacturers categorically do not recommend the repair of gas burners or their disassembly on their own, without the participation of a specialist.

Piezo Models

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 torch with piezo ignition has wide functionality, a modification of this type is especially popular among tourists, hunters, fishermen. In addition, the device is used for soldering some materials.

Varieties:

  • Portable models. They are a construction of a cylinder with a fuel mixture and a special nozzle mounted on a tank with gas or through an adapter in the form of a hose. The features of this type include the ability to install on the upper part of the casing of a dish of suitable diameter.
  • Tabletop versions are horizontal devices with a large cooking surface. The gas cylinder is placed in the hull, is fixed with a grip. Such modifications can be connected through a special adapter.
  • Combined burners. The device is made in the form of nozzles, which are equipped with a small tank with gas.

Device

The design of a gas torch with piezo ignition includes a nozzle for feeding a flame, a fuel regulator, a piezo element (actuated by a button or trigger). The modifications under consideration owe their popularity to ease of maintenance and low cost. The simplest option is a gas jet divider with a power corrector. The last element is wound directly on the container, additionally plays the role of the stand. Among the advantages are compact dimensions, low price, low weight.
