General Construction of Gas Boilers

1. Air supply system. The function of the air supply system is to send a certain amount of air with a certain wind speed and volume into the combustion chamber. Its main components include: the shell, fan motor, fan impeller, gun barrel, air door controller, air door baffle, cam adjustment mechanism, and diffusion plate.
2. Ignition system. The function of the ignition system is to ignite a mixture of air and fuel, and its main components include: ignition transformer, ignition electrode, and high-voltage electric fire cable. A relatively safe ignition system is called an electronic pulse igniter, which is widely used by gas boiler manufacturers such as Zhuoyi Energy Conservation. It is convenient and time-saving, only needs to be pressed with fingers, and has high safety. There will be no safety accidents caused by accidental shutdown. Once the shutdown occurs, the control system can timely close the solenoid valve and cut off the gas path.
3. Monitoring system. Its function is to ensure the safe and stable operation of the burner, and its main components include flame monitors, pressure monitors, temperature monitors, etc.
4. Fuel system. The function of the fuel system is to ensure the fuel required for combustion in the burner. The fuel system of a fuel burner mainly includes oil pipes and fittings, 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. Electronic control system. The electronic control system is the command center and contact center of the above systems, with the main control component being the programmable controller. Different programmable controllers are equipped for different burners. Common programmable controllers include LFL series, LAL series, LOA series, and LGB series, with the main difference being the timing of each program step.
