| 摘 要： | 北京某热电厂由于建设场地限制不能实现每台机组配1座逆流式自然通风冷却塔的设想,从而建造了2台机组共用的1座横流式自然通风冷却塔。但是关于这座塔从冷却效率到结冰防冻的争议一直没有停止过,期间曾进行过部分改造,但是没有找到症结所在。通过剖析各种问题的根源,证明经过技术改造可以满足200MW机组循环冷却水的要求,短期内不可能带满该负荷时也需要对几个方面进行彻底改造,否则仍将付出不必要的代价。

| Abstract: | A certain thermal power plant in Beijing can not realize one reverse-flow natural draft cooling tower for each unit limited by construction site and needs to build a common transverse-flow natural draft cooling tower for both units.However,controversy about its cooling efficiency,icing and ice proof from operation start to now has never been stopped,and some retrofitting has been done during the period,but the crucial reason has not been found.By analysing various origins of problems,technical retrofitting ... |
