摘要
着重介绍２００ＭＷ机组凝汽器铜管酸洗除垢、氧化剂预膜工艺，化学清洗过程及清洗效果的检查与评价，最后围绕着铜的氧化膜形成过程、形态及其耐蚀性的问题进行了深入地讨论．
The process of scale removal by acid cleaning and passivation with oxygenant on brass tube in 200MW unit condenser, and the chemical cleaning procedures, the check and evaluation of chemical cleaning effect are emphatically introduced. At last, the formation and corrosion resistance of copper oxiode film have been discussed deeply.
