摘　　要：为了提高电厂循环水系统运行的安全可靠性,降低建设运营成本,通过对某空冷机组尖峰冷却系统的循环水系统的介绍,指出了凝汽器高位布置的循环水系统在设计运行过程中应重点关注的事项,论述了电厂循环水系统循环水泵流量复核的方法,分析了胶球冲洗系统收球率低的原因及解决措施,以供同行设计参考。In order to improve the safety and reliability of circulating water system operation in power plants and reduce construction and operation costs,based on the introduction of the circulating water system of the peak cooling system of certain air cooling unit,the matters that should be particularly concerned about in design and operation process of circulating water system of condensers with high position arrangement are put forward,and the pump flow double-check method of circulating water system in power plants is expounded.The causes of low ball-collecting rate of the rubber ball washing system and the countermeasures are also analyzed,so as to offer reference for peer design.
