As a kind of mechanical and electrical integration equipment with a high degree of automation, the burner can be divided into five major systems from its functions: air supply system, ignition system, monitoring system, fuel system, and electronic control system.
The function of the air supply system is to feed air with wind speed and air volume into the combustion chamber. Its main components are: shell, fan motor, fan impeller, air gun fire tube, air door controller, air door baffle, and diffuser.
The function of the ignition system is to ignite the mixture of air and fuel, and its main components are: ignition transformer, ignition electrode, electric fire high-voltage cable.
The function of the monitoring system is to ensure the safe operation of the burner. Its main components are flame monitor, pressure monitor, external monitoring temperature device, etc.
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, and ignition solenoid valve groups.
The electronic control system is the command center and contact center of the above systems. The main control element is the program controller. Different burners are equipped with different program controllers. 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. Mechanical type: slow response, Danfoss, Siemens and other brands; electronic type: fast response, domestically produced.
