The structure of the gas burner consists of the following five systems: air supply system. The function of the air supply system is to send air with a certain wind speed and air volume into the combustion chamber. Its main components include: shell, fan motor, fan impeller, air gun fire pipe, damper controller, damper baffle, cam adjusting mechanism and diffuser.

   The function of ignition system is to ignite the mixture of air and fuel. Its main components include ignition transformer, ignition electrode and electric fire high-voltage cable. The function of the monitoring system is to ensure the safe and stable operation of the burner. Its main components include flame monitor, pressure monitor, temperature monitor, etc.

   The function of the fuel system is to ensure the fuel required for burner combustion. The fuel system of fuel burner mainly includes: oil pipe and joint, oil pump, solenoid valve, nozzle and heavy oil preheater. The gas burner mainly includes filter, pressure regulator, solenoid valve group, ignition solenoid valve group and fuel butterfly valve.

   The electric control system is the command center and contact center of the above systems. The main control element is the program controller. Different program controllers are equipped for different burners. The common program controllers are LFL series, LAL series, loa series and LGB series. The main difference is that the time of each program step is different.
