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 are: casing, fan motor, fan impeller, air gun fire tube, damper controller, damper baffle, and diffusion plate.
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.
3. Monitoring system
The function of the monitoring system is to ensure the safe operation of the burner. The main components of the coating production line include flame monitors, pressure monitors, external monitoring thermometers, etc.
4. Fuel system
The function of the fuel system is to ensure that the burner burns the fuel it needs. The fuel system of the oil burner mainly includes: oil pipes and joints, oil pump, solenoid valve, nozzle, and heavy oil preheater. Gas burners mainly include filters, pressure regulators, solenoid valve groups, and ignition solenoid valve groups.
5. Electronic control system
The electronic control system is the command center and contact center of each of the above systems. The main control component is a programmable controller. Different programmable controllers are equipped for different burners. Common programmable controllers are: LFL series, LAL series, LOA series, and LGB series. , the main difference is the time of each program step. Mechanical type: slow response, Danfoss, Siemens and other brands; electronic type: fast response, domestically produced.
