摘要/Abstract

摘要： 针对烟气换热器换热元件表面结垢导致的压差超标的问题，对清洗方法进行了改进，对GGH进行了部分改造，提高了脱硫系统运行的可靠性。同时，指出了改造后仍然存在且需要进一步研究并处理的问题。

关键词: 结垢堵塞, 压差超标, 清洗改进

Abstract: Aiming at the overproof problem of pressure difference of GGH caused by fouling on the heat exchange elements surface, the cleaning method was improved, and the GGH was reformed partially. The operation reliability of desulphurization system was enhanced. In addition, some problems, which still exists after the reformation and needs further research and treatment, were pointed out.

Key words: foulinging and blockage, overproof of pressure difference, improvement of cleaning
