The natural gas boiler burner is an important combustion equipment in the auxiliary equipment of the gas boiler. The natural gas boiler burner can be divided into natural gas burners, city gas burners, liquefied petroleum gas burners and biogas burners.

Working principle of natural gas boiler burner

　　The natural gas boiler controls the combustion through the burner. The natural gas boiler burner is responsible for mixing fuel and oxygen in the boiler content, igniting it through an ignition device, and continuously burning and heating the water inside the boiler. The natural gas boiler burner, as a highly automated mechatronics equipment, can be divided into five major systems: air supply system, ignition system, monitoring system, fuel system, and electronic control system:

　　1. The function of the air supply system is to send air with a certain wind speed and volume into the combustion chamber. Its main components are: shell, fan motor, fan impeller, air gun fire tube, air door controller, air door baffle plate, cam adjustment Institutions, diffusion plates.

　　2. 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 high-voltage cable. The flame length, cone angle and shape can be designed according to user requirements.

　　3. The function of the monitoring system is to ensure the safe and stable operation of the burner. Its main components are flame monitor, pressure monitor, temperature monitor, etc.

　　4. The function of the fuel system is to ensure the fuel required for the combustion of the burner. 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, ignition solenoid valve groups, and fuel butterfly valves.

　　5. The electronic control system is the command center and contact center of the above systems. The main control element is the program controller, which is equipped with different program controllers for different burners. Common program controllers are: LFL series, LAL series, LOA series, The main difference of the LGB series is the time of each program step.
