Working principle of gas burner: when combustible gas (city gas, natural gas, liquefied petroleum gas) is controlled by the microcomputer control system according to the program into the burner head, by the primary air and combustible gas mixture, ignition combustion, secondary air combustion, to achieve full combustion.Combustion condition by the flame automatic tracking system detection and control of combustion, when the combustion failure (combustion chamber hypoxia, combustible gas under pressure, combustible gas cut-off, insufficient gas volume, etc.), the control system issued instructions, the solenoid valve of the gas supply system quickly closed, cut off the gas power supply, the burner automatic purge after shutdown, indicating the fault.
