托电2号炉火焰检测系统优化

Optimization of Flame Detection System of Tuoketuo Power Plant Unit 2

托电2号机组火检系统自运行以来,存在一些问题,如火检系统经常发出故障报警信号、火检探头的使用寿命较短、火检信号存在"偷看"现象等。针对以上问题,热控专业人员经过认真分析找到了原因所在,提出了行之有效的解决方法,并结合2号机组的检修对火检系统进行了优化改造。

Since Tuoketuo Power Plant unit 2 was put into operation, the flame detection system has lots of problem, such as fault signals alarm occurred frequently, service life of the flame detector was shorten, and fire detectors always peep others. To solve these problems, after careful analysis the control maintenance engineers found the cause and put forward the appropriate measures. Combined with the repairing opportunity of unit 2, the flame detection system has been optimized.
