FLAME DETECTING DEVICE OF A BOILER

摘要

The flame sensing device of a boiler is capable of sensing whether the flame of the gas or oil boiler is normal by using a photo-electric tube sensing, a flame rod rectifying, and an ultraviolet rays radiation sensing methods. The flame sensing device is comprised of a photo-electric tube type flame sensor(10) for sensing the flame by means of a photo-electric tube; a flame rod rectifying type flame sensor(20) for sensing the flame in a flame rod rectifying manner; and an ultraviolet rays radiation sensing type of flame sensor(30) for sensing the flame in an ultraviolet rays radiating sensing manner.
