640MW机组凝汽器不锈钢管结垢分析和处理

Scaling Analysis and Processing of 640 MW Supercritical Steam Turbine Condenser Stainless Steel Tube

某电厂二期2×640 MW进口机组凝汽器为北重ALSTOM配套产品,由于在运行中循环水加药量、浓缩倍率等控制不当造成凝汽器钢管大面积结垢。在分析了凝汽器钢管结垢原因以及介绍了几种处理方法后,并着重分析了化学清洗的原理过程以及凝汽器化学清洗前后的参数对比,说明化学清洗在处理凝汽器钢管结垢工作中的重要作用。

One power plant second period 2×640 MW imported unit condense are BeiChong ALSTOM auxiliary products,thus in operating process,improper control of cycle water add medicine and concentrate radio cause condense steel tube scaling in large area.The article analyzes condense steel tube scaling reason and introduce some ways,and analyzes che chemistry cleaning process and condense parameter contrast before and after chemical cleaning,explain chemistry cleaning important role in condense steel tube scaling work.
