Abstract:

Abstract:Taking the supercritical opposed firing once through boiler of Shanxi Xingneng Power Generation Company Limited as example, the forming process of hightemperature sulfur corrosion of water wall was described. The advantages of the supersonic electric arc spraying coating on prevention of hightemperature corrosion were put forward. The technology of supersonic electric arc spraying and the characteristics of the coating were introduced. The arc spraying on the boiler water wall was accomplished, and the wearresisting and corrosion resistance performance of the tube surface of the water wall were improved.
