Analysis on reasons of hightemperature corrosion of water wall in supercritical boiler and reformation measures

Abstract

Abstract:

Abstract:Aming at the hightmperature corrosion and lagging of the boiler No.4 in a power plant, the reason of slagging was analyzed, and some reformation measures were adopted, whch include to reform the refractory belt, to adjust the dense and dilute ratio of the richlean separator of the plverizing system,to balance the primary air and to optimize lownitrogen combustion regulating method. After the reformation, the boiler operation parameters can satisfy the tchnical requirements, the slagging in furnace was eliminated, and the safe and economical operation of the boiler was ensured.

Key words: Keywords:supercritical boiler, hightemperature corrosion, slagging, refractory belt, combustion adjustment
