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

having good effectiveness.
