Abstract

Abstract:

Abstract:The foul block problem of return valve standpipe of a certain circulating fluidized bed boiler is frequently occurred. Through analyzing,
this paper found that the main reason is the low pressure of high-pressure fluid air,and proposed some pertinence measures from the aspects of operation,equipment transformation and technical management.After that,foul block problem of return valve standpipe is solved satisfactorily.

Key words: ,

Keywords:boiler, circulating fluidized bed, return valve, standpipe, pipe blocking
