燃气-蒸汽联合循环机组余热锅炉化学清洗方案探索

Exploratory of Chemical Cleaning Program for HRSG of Gas-steam Combined Cycle Unit

以某电厂为例,在化学清洗导则的基础上,对余热锅炉结构进行了分析,制定了该类型余热锅炉化学清洗方案,并针对该方案操作周期长的缺点,做了进一步尝试性优化。

Based on chemical cleaning guidelines and practical power plant operation, structure of HRSG was analyzed and chemical cleaning program for this type of HRSG was established. Furthermore,trial optimization was given aimed at the long cleaning term.
