俄制500MW汽轮机运行中凝汽器循环水单侧隔离查漏方法

Single Side Isolated Leak Detection of Condenser Circulating Water in Operation of 500MW Russian Steam Turbine

凝汽器较普遍存在着泄漏问题,随着凝汽器运行时间的延长,泄漏问题越来越突出。华能伊敏电厂1号机组凝汽器在2017—2018年先后发生三次泄漏,阐述泄露原因,介绍了在机组运行中实施的凝汽器单侧隔离查漏方法,并介绍了预防凝汽器冷却水管泄露的方法。

The condenser leakage problem is quite common. With the extension of the condenser operation time, leakage problem becomes more and more prominent. The condenser of unit 1 of Huaneng Yimin Power Plant experienced three leakage successively in 2017-2018. This paper expounds the reasons for the leakage, introduces the single-side isolated leak inspection method of the condenser in operation of the unit, as well as the method of preventing the leakage of the condenser cooling pipe.
