间接空冷机组循环水系统清洗措施

Cleaning methods of circulating water system of indirect air-cooled unit

间接空冷塔在电厂冷却系统的应用越来越广泛,但对机组投运前循环水管道水箱系统的清洗还没有相应的规范。结合工程实践,以660 MW机组间接空冷机组为例,对间接空冷系统循环水管道和水箱的清洗措施进行了论述,可为间接空冷系统工程循环水系统的施工和调试提供借鉴。

The indirect air-cooling tower is more and more widely used in power plant cooling systems. Before the unit is put into operation,the circulating water tank and piping system must be cleaned,and there is not relevant specification on this yet.Combining with engineering practice,taking a 660 MW indirect air-cooled unit as example,the cleaning methods of the circulating water pipes and tanks of indirect air-cooling system were expounded,which can be used as reference for indirect air-cooling system in construction and debugging of circulating water system.
