In recent years,due to the extensive blending of economic coal in power plants,the problem of high-temperature corrosion of boiler water-cooled walls has become increasingly serious.With the continuous improvement of boiler unit parameters,some units have experienced severe corrosion,increasing the difficulty of treatment.The frequent shutdown accidents seriously affect the safe and stable operation of boilers,and frequent shutdown maintenance and building material replacement have caused serious economic losses to various power plants.It is urgent to study practical and feasible measures for preventing high-temperature corrosion of boiler water-cooled walls.This article systematically analyzes the causes and influencing factors of severe high-temperature corrosion of boiler water-cooled walls,and summarizes the current advanced prevention and control measures for high-temperature corrosion of boiler water-cooled walls,in order to provide technical ideas for various power plants to solve the problem of high-temperature corrosion of boiler water-cooled walls.
