The flame monitor is a flame monitoring device for an incinerator. The device integrates optics, mechanics, and electronics. The image in the furnace is presented to the camera target surface through the optical system in the lens tube. The camera converts the light signal into a video signal and transmits it to the monitor in the control room via a video cable. The operator can see the real image of the fuel burning in the furnace on the monitor in the control room. The flame monitor can monitor in time when the boiler is ignited, running at a low load, or when the fuel delivery system fails, so that the staff can take corresponding measures. The flame monitor is an indispensable device for the safe and economical operation of the furnace. Since the flame monitor is in the high temperature environment of the incinerator, it is necessary to provide it with protective equipment so that it can work normally under low temperature conditions.
