Discussion on Performance Index of the Anti - Contamination Coating for the Heating Surface of Pulverized Coal Boiler

Abstract

In order to help the material manufacturers and research units to understand, develop and optimize the anti - contamination high temperature nano - ceramic coating with a clear target and to have a comprehensive understanding of the coking problem that the coal boilers are faced with, based on the characteristics of both boiler operation and coating, the performances of the anti - contaminant coating for the heating surface of boiler including heat resistance, adhesion strength, abrasion resistance, thermal shock resistance, thermal conductivity, anti - contamination and high temperature corrosion resistance were discussed, and the development trend of anti - contamination coating used in high temperature heating surface of pulverized coal boiler was prospected.
