摘要： 摘要：针对某些电站锅炉水冷壁管泄漏造成锅炉停机的案例，通过分析确定泄漏原因为除灰器故障造成水冷壁管吹损。采取了改造汽源、加装吹灰器故障在线监测装置及锅炉吹灰优化监测装置等措施，以减少锅炉受热面因吹损泄漏造成的非正常停机，提高机组运行的安全性和经济性。

Abstract: Abstract:Some cases of boiler shutdown accident caused by leakage fault of water wall tubes of power plant boiler were described. Based on analysis, it was determined that the leakage fault of water wall tubes is caused due to soot blower fault. The steam source of the soot blower was reformed. The soot blower fault online monitoring device and the boiler soot blowing optimization monitoring device were installed additionally. The abnormal shutdown accident due to boiler heating surface leakage caused by soot blower fault was reduced, and the safety and economic efficiency of the unit operation were improved.
