330MW机组氢气泄漏问题的分析及处理

氢冷发电机组的漏氢量大小直接影响到发电机组的安全稳定运行,是发电机安评的一个重要指标。文章介绍了大唐桂冠合山发电有限公司（以下简称合山发电公司）的＂北重＂产330MW机组漏氢量超标的原因分析及在检修中对#2机组漏氢分析、处理的经验,对火力发电厂同类型机组处理漏氢问题具有一定的借鉴意义。

The Analysis and Treatment of Hydrogen Leakage of 330 MW Machine Unit

The amount of hydrogen leakage directly affects the stability of the generation unit,so it is also an important indicator of security assessment of the generation unit.The article introduces the reasons behind and the brief analysis on the handling of hydrogen leakage of 330 MW machine unit produced by Beizhong of Datang Guiguan Heshan Power Generation Co.,Ltd.（hereafter referred to as Heshan Power Generation Company）,it also gives analysis to the reasoning of the leakage of the machine #2,which provides meaningful reference to the similar machine unit of fire-based power generation plants.
