Analysis on reasons of leakage of heating surface of power plant boiler and preventive measures

Abstract

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.
