Abstract

Abstract: The hightemperature corrosion occurred in the water walls of two 660MW supercritical oncethrough boilers in a power generation company limited. The factors leading to hightemperature corrosion of the water wall were pointed out. The gas temperature and the chemical components of the gas in side wall of water wall were detected. The reasons of the hightemperature corrosion of water wall were analyzed; and the relevant preventive measures were proposed.

Key words: water wall, high-temperature corrosion, reason analysis, preventive measure
