给水再循环布置优化方案对比分析

Comparing and Analysis of Feed Water Recirculation Arrangement Scheme

文中对给水再循环两种不同的布置方案进行比较,并对这两个方案从力、力矩以及最大热位移,这三个方面进行了对比和分析,最后得出300 MW及以上大中型电站,不论从设计还是从运行角度考虑对给水再循环布置均采用调节阀组设置在除氧器平台附近都较为合理。

Through comparing two type arrangement of feed water recirculation pipe,and comparing and analyzing from force,moment and maximum warm displacement aspect,at last we reduce above300 MW and so on large and medium plant power feed water recirculation control valve should be layout near deaerator platform,It is a reasonable scheme.
