The working principle of the flame detector of the cracking furnace in the waste acid cracking unit is introduced,the causes of the unstable flame detection signal are analyzed,and the solutions are put forward.The installation position of the flame detector,the environment in the cracking furnace,the acid gas composition,the feed temperature and the combustion air volume are important factors affecting the stability of the flame detection signal.By adjusting the installation position of the flame detector,controlling the inlet flow of compressed air,increasing the hydrogen sulfide concentration in the acid gas,controlling the furnace temperature and feed temperature of the combustion chamber,reasonably adjusting the air distribution ratio,and continuously improving the detection equipment and operating parameters,the problem of unstable flame detection signal is solved,which lays a foundation for the stable operation of the device.
