600MW间接空冷机组的设计及应用

介绍了阳城发电有限责任公司600MW间接空冷机组的结构设计特点及其与传统水冷机组的主要结构差异,分析了间接空冷机组在工程应用中出现的问题,包括凝结水水质差,含盐量大,导电度超标,树脂过滤器失效快,冬季空冷岛散热器易冻裂,夏季凝结水温高、背压高,机组运行安全性、经济性差,空冷机组厂用电率高等,针对出现的问题,提出了相应的改进措施,实践证明这些措施效果良好。

The Design and Application of 600 MW Indirect Air-cooling Units

This paper introduces the design features of the design-structure of 600MW indirect air-cooling units in Datang Yangcheng Power Generation Co.,Ltd and their main differences comparing with traditional water-cooling units,and analyzes some problems occurring in engineering application of indirect air-cooling units such as the poorer quality of condensation water,the higher salt content,the superstandard electric conductivity,the fast failure of resin filter,the easier frost cracking of air cold island radiat...
