Abstract

The invention discloses a flame detector cooling device which comprises a flame detector probe (1), a cooling air blow-off nozzle (2) of the flame detector probe, an outer cooling tube (3), an optical fiber (4) and an inner cooling tube (5). The flame detector cooling device is characterized in that the flame detector probe (1) is arranged in the outer cooling tube (3); the inner cooling tube (5) is sleeved in the outer cooling tube (3); and the optical fiber (4) is arranged in the inner cooling tube (5), one end of the optical fiber (4) is connected to the flame detector probe (1) while the other end of the optical fiber is connected to an external system, and a flame detecting optical fiber protecting pipe is changed from a single-layered cooling air duct into a double-layered cooling air duct, so that problems that the optical fiber is easy to damage, the flame detecting probe is easy to clog and the like are solved.

Description

technical field [0001] The invention relates to a flame detector cooling device and method, belonging to the technical field of boiler flame detection. Background technique [0002] In the process of thermal power production, the function of the flame detector runs through the whole process from the start of the boiler to the full-load operation, and is used to judge the establishment / extinguishment of the flame in the whole chamber or the unit burner or whether there is fire or no fire, and the equipment is running The reliability and detection accuracy are directly related to the operation safety and stability of the unit. Since the detection system was put into operation, there have been frequent failures such as fiber optic burnout and flame detection probes being blocked by ash, which have seriously threatened the safe and stable operation of the unit. By changing the flame detection optical fiber sheath tube from a single-layer cooling air duct to a double-layer cooli...
