As the name implies, the boiler burner refers to the burner used on the boiler. The boiler burner is the most important equipment in the supporting auxiliary equipment of the fuel gas boiler. The boiler burner is mainly divided into oil burner, gas burner and dual fuel burner (also It is called oil and gas dual-purpose burner), among which oil burners can be divided into light oil burners and heavy oil burners. Light oil mainly refers to diesel oil, and heavy oil refers to the heavy oil left after crude oil extracts gasoline and diesel oil; Burners can be divided into natural gas burners, city gas burners, liquefied petroleum gas burners and biogas burners.
Boiler burner, as a kind of mechatronics equipment with high degree of automation, can be divided into five major systems from the functions it realizes: air supply system, ignition system, monitoring system, fuel system, and electric control system.
1. Air supply system
The function of the air supply system is to send air with a certain wind speed and volume into the combustion chamber. Its main components are: housing, fan motor, fan impeller, air gun fire tube, damper controller, damper baffle, cam adjustment mechanism, Diffuser disc.
2. Ignition system
The function of the ignition system is to ignite the mixture of air and fuel. Its main components are: ignition transformer, ignition electrode, and electric fire high-voltage cable. Flame length, cone angle and shape can be designed according to user requirements.
3. Monitoring system
The function of the monitoring system is to ensure the safe and stable operation of the burner. Its main components include flame monitors, pressure monitors, temperature monitors, etc.
4. Fuel system
The function of the fuel system is to ensure that the burner burns the required fuel. The fuel system of the oil burner mainly includes: oil pipes and joints, oil pumps, solenoid valves, nozzles, and heavy oil preheaters. Gas burners mainly include filters, pressure regulators, solenoid valve groups, ignition solenoid valve groups, and fuel butterfly valves.
5. Electric control system
The electronic control system is the command center and contact center of the above systems. The main control element is the program controller, which is equipped with different program controllers for different burners. The common program controllers are: LFL series, LAL series, LOA series, LGB series , the main difference is that the time of each program step is different.
Classification of boiler burners
Boiler burners have various classification methods according to their different attributes. According to the fuel method, it is divided into oil burner, gas burner and dual fuel burner. Among them: in specific applications, oil burners will be divided into light oil burners, heavy oil burners, etc.; gas burners are divided into natural gas burners, city gas burners, etc. Divided according to the combustion control method of the burner: single-stage fire burner, double-stage fire burner, proportional adjustment burner. According to the fuel atomization method, it is divided into: mechanical atomization burner, medium atomization burner; according to the structure, it is divided into: integral burner and split burner. Among them, the split burner is mainly used in industrial production. Its main feature is that the combustion system, air supply system, and control system are all disassembled and installed. This kind of machine is mainly suitable for special working environments such as large equipment or high temperature.
Precautions for the use of boiler burners:
1. When connecting the peripheral circuit and realizing automatic control of boiler temperature, pressure, water level, etc., please connect according to the wiring diagram of the control system.
2. The oil suction pipe should not be close to the bottom of the fuel tank, and a distance of 80--120mm should be kept. The burner should be turned off before filling the fuel tank, and the fuel can be injected into the fuel tank after being filtered, and can be restarted after 20 minutes of fuel filling. The oil system must not leak oil or air. Check whether the fuel tank is sufficient before starting the burner.
3. The size of the damper should match the specification of the nozzle. When the burner is in use, since the equipped boiler is inconsistent with the boiler used for debugging when the burner leaves the factory, it is generally necessary to properly adjust the damper, and sometimes it is necessary to replace the oil nozzle with appropriate specifications and spray angles.
4. The ambient temperature of the burner must not exceed 70°C, otherwise cooling and heat insulation measures should be taken. When used in colder regions, appropriate thermal insulation measures should be taken for the oil storage device and the oil supply and return pipeline system to prevent the oil circuit from being blocked due to freezing. At the same time, the control circuit part of the burner must not be exposed to moisture or high temperature. Turn off the burner when sweeping the chimney.
5. The motor should be protected from moisture and should not be used in a humid environment.
6. The burner should be installed in a balanced manner, and should be used horizontally or vertically, and should not be used at an angle.
7. When it is inconvenient to directly operate the burner, an external control switch and electrical protection device should be connected.
8. Frequently check whether the connection between the burner and various components is firm, whether it is loose, and whether the position has changed.
9. When the burner is started, be careful not to hurt people and destroy things by the sudden flames.
The burner is easy to understand, actually refers to the boiler burner, boiler burner gas boiler is an important supporting auxiliary equipment, the boiler burner is mainly divided into oil burner and gas burner and dual fuel burner, including fuel burner It can be divided into light oil burners and heavy oil burners. Light oil mainly refers to diesel oil, and heavy oil refers to the heavy oil left after oil is extracted from gasoline and diesel oil; gas burners can be divided into natural gas burners, city gas burners, liquefied petroleum gas burners and biogas burners.
The heavy oil burner is a combustion device specially designed to improve the combustion performance of heavy oil with high viscosity and poor atomization performance. It is mainly composed of heavy oil tank, diesel tank, oil filter, heavy oil supply pump, heat exchanger, light and heavy oil switch valves, fuel pump, pressure regulating valve, burner and its delivery pipeline.
The burner protection system includes explosion-proof door, heating system pressure protection, water level protection, wind pressure protection, high pressure protection, low pressure protection, flame monitoring protection, etc. When the burner is actually working, various protection signals are sent to the program controller. Among the protection signals received by the program controller, the burner can only be started when all the protection signals are normal.
During the installation process, the tightness of the gas pipeline was checked. Generally, it should not be disassembled. When disassembly is required, the airtightness of the pipeline should be checked after reconnection. When the gas supply pressure is found to be abnormal, the burner should be turned off in time.
When the filter on the gas pipeline is dirty, close the valve on the pipeline and clean (or replace) the filter on the gas pipeline. The photosensitive area in front of the photosensitive eye should be kept clean. Please take it out, it needs to be wiped down periodically. However, please note that when putting the photosensitive eye back into the socket, the photosensitive part of the eye should face forward.
The temperature near the burner should not be too high, otherwise it will damage some parts of the burner, especially the control box. The vicinity of the burner should be kept clean, and no debris should be piled up, so as not to be sucked by the burner and cause losses.
