High-temperature Corrosion of Water-wall in Supercritical Boiler

Abstract

Abstract. With the development of large capacity and high parameters of power plant boiler, water wall high temperature sulfur corrosion of coal-feed boiler is becoming more and more frequent. Some of these corrosion even have affected the boiler operation safety. In this review, the domestic research in high temperature sulfur corrosion was summarized, combining with the foreign corresponding research, discussed the types of corrosion and the formation mechanism, and factors which affecting the corrosion, and the prevention methods.
