The construction of the gas burner consists of the following 5 systems:
1. Air Supply System. The function of the air supply system is to deliver air with a certain wind speed and volume into the combustion chamber. Its main components include: housing, fan motor, fan impeller, air gun fire tube, damper controller, damper blade, cam adjustment mechanism, and diffuser disk.
2. Ignition System. The function of the ignition system is to ignite the air-fuel mixture, with its main components including: ignition transformer, ignition electrode, and high-voltage ignition cable. A relatively safe type of ignition system is the electronic pulse igniter, widely used by manufacturers such as Zhuoyi Energy-Saving for gas boilers. It is convenient and time-saving, requiring only a finger press, and offers high safety, preventing accidents due to unexpected extinguishing. In case of extinguishing, the control system can promptly close the solenoid valve to shut off the gas supply.
3. Monitoring System. Its function is to ensure the safe and stable operation of the burner, with main components including flame monitor, pressure monitor, temperature monitor, etc.
4. Fuel System. The function of the fuel system is to ensure the fuel required for the burner's combustion. The fuel system of oil burners mainly includes: fuel pipes and connectors, fuel pumps, solenoid valves, nozzles, heavy oil preheaters. Gas burners primarily consist of filters, regulators, solenoid valve groups, ignition solenoid valve groups, and fuel butterfly valves.
5. Electrical Control System. The electrical control system serves as the command and communication center for the aforementioned systems, with the main control components being programmable controllers. Different programmable controllers are available for different burners, commonly including the LFL series, LAL series, LOA series, and LGB series. The primary difference among them lies in the varying time intervals of the program steps.
