发电机内冷水处理技术的探讨

On treating techniques of generator inner cooling water

目前国内外大、中型发电机内冷水处理技术普遍存在问题,造成发电机内冷水电导率和pH值达不到有关标准规定的要求。文章介绍了一种新型的发电机内冷水超净化处理技术及其应用。该技术在发电机内冷水处理方面有所创新,技术的综合性能指标达到国际先进水平。针对目前沙角C电厂660MW机组和沙角A电厂200MW机组发电机内冷水系统结构方式及运行状况,提出采用新型发电机内冷水超净化处理技术及改造内冷水处理系统的建议。

The conductivity and pH value of generator inner cooling water can not attain the relevant standards when treated with conventional treating techniques at home and abroad. This paper describes an innovative superpurifying technique for generator inner cooling water along with its applications;the comprehensive performance indices of the technique attain the international advanced level. In view of the present configuration and running of generator inner cooling water system on 660 MW units in Shajiao C Power Plant and 200 MW units in Shajiao A Power Plant,the use of the superpurifying technique and the modification of system are suggested.
