300MW发电机组闭冷器的改造总结

Transformation summary of 300MW generating units closed cooler

深圳妈湾电力有限公司#5、#6发电机组原配板式闭冷器运行效果不理想、运行成本高,且已严重影响到发电机组的正常运行。采用新型折流杆结构管式换热器对板式闭冷器进行改造。改造后闭冷器的换热性能更好,运行安全可靠,系统简单,维护工作量少,运行成本较低。且改造成本低,投资成本回收周期短,具有重要应用价值。

Shenzhen Mawan power company limited #5、#6 Plate heat exchanger operation with generator makes desirable results, high running costs, and has seriously affected the normal operation of generators. New architecture of rod baffle tubular heat exchanger on the plate heat exchanger to be transformed. Modification of heat transfer in heat exchangers better performance, reliable operation, the system simple, low maintenance and running costs low. And renovation costs low investment cost-recovery cycle is short, is of great value.
