摘要/Abstract

摘要： 以某火力发电厂为例，介绍了闭式水系统膨胀水箱长期处于溢流状态，机组补水率较高的异常情况，论述了漏点查找的方法，实施后降低了机组补水率，供解决类似问题时参考。

Abstract: In a power plant, the overflow state existed in the expansion tank of the closed cooling water system for long time, and the makeup water percentage of the unit was higher. The method for finding the leakage point was expounded. The device existing leakage fault was replaced, and the makeup water percentage was decreased. The result in this paper provides reference for solving similar problems.

Key words: closed cooling water system, expansion tank, overflow, leakage point find, make-up water percentage
