菏泽发电厂300MW机组给水处理方式由AVT(R)改为AVT(O)的实践
摘要
菏泽发电厂300MW机组给水处理设计为还原性全挥发处理(AVT(R))方式
改为弱氧化性全挥发处理(AVT(O))方式后
给水铁、铜含量减少
金属表面形成了致密的Fe2O3保护膜
热力系统冲刷腐蚀现象减轻
效果良好。
Abstract
The feed-water treatment mode of 300 MW unit in Heze Power Plant had been designed as reductive all volatile treatment(AVT(R)).After changing the treatment mode into weakly-oxidized all volatile treatment(AVT(O))
the iron and copper content in feed-water has been reduced
and a compact protective film of Fe2O3 being formulated on the surface
the erosion phenomenon in the thermodynamic system being weakend
