Application of high pressure water washing on anair preheater of boiler

Abstract

Abstract:

Abstract:The on line water washing technology for an air preheater has the advantages of low cost,easy operation,little influence on equipment,
reducing the differential pressure of air preheater,preventing blockage etc.This paper took the No.3 generator unit of Huadian Weifang Power Generation Company Limited as an example, discussed the operation steps of highpressure water washing on air preheater and problems that should be noticed. After that, the experience of online water washing technology for air preheater is summarize.

Key words: ">Keywords:">air preheater, differential pressure, washing, Ammonium hydrogen sulfate, low temperature corrosion, energy conservation
