摘要
介绍了烟气换热器(GGH)在运行中极易结垢、堵塞等问题,及其造成的危害;对某电厂脱硫系统中GGH的垢样进行分析,提出了结垢产生的原因,针对该垢开发出清洗药剂,进行喷淋试验,最终达到良好的除垢效果。
The problems of scaling and blocking which exist in gas-gas heater is introduced,and the damage is described.The scale sample of desulfurization system of a power plant is analyzed,the reason cause scaling is put forward,the corresponding scale cleaning agent is developed,and spray test for the agent is conducted,and good result is obtained.
