Basic knowledge of burner in asphalt mixing plant

　　As a kind of mechanical and electrical integration equipment with high degree of automation, burner can be divided into five systems from its functions: 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 certain wind speed and air volume into the combustion chamber. Its main components are: shell, fan motor, fan impeller, air gun fire pipe, air door controller, air door baffle and diffusion plate.

　　2、 Ignition system

　　The function of ignition system is to ignite the mixture of air and fuel. Its main components are: ignition transformer, ignition electrode, high-voltage electric fire 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 are flame monitor, pressure monitor, external temperature monitor, etc.

　　4、 Fuel system

　　The function of the fuel system is to ensure the fuel required for combustion of the burner. The fuel system of oil burner mainly includes: oil pipe and joint, oil pump, solenoid valve, nozzle, heavy oil preheater. Gas burners mainly include filters, regulators, solenoid valve groups and ignition solenoid valve groups.

　　5、 Electronic control system

　　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 procedure step is different. Mechanical: slow response Danfoss, SIEMENS and other brands; electronic: fast response, domestic.
