Gas burner principle

When the combustible gas (city gas, natural gas, liquefied petroleum gas) is controlled by the microcomputer control system into the combustion head of the burner according to the program, the primary air is mixed with the combustible gas, ignited and burned, and the secondary air helps the combustion to achieve full combustion. The combustion status is detected and controlled by the flame automatic tracking system. When the combustion is faulty (the combustion chamber is oxygen deficient, the combustible gas is under pressure, the combustible gas is interrupted, the gas volume is insufficient, etc.), the control system issues a command that the solenoid valve of the gas supply system is rapidly closed , Cut off the gas supply, the burner automatically shut down after the purge, indicating failure.
