[0002] The front flame detector is an important device in the boiler furnace safety monitoring system. Its function is to conduct real-time detection of the combustion conditions based on the combustion characteristics of the flame. Once the flame combustion state does not meet normal conditions or is extinguished, a signal is given in a certain way to ensure that the fuel supply is stopped when the boiler is extinguished.
