摘　　要：循环水高位收水冷却塔雨区跌落高度小,系统静扬程小,具有噪音低、节能明显等优势,在目前大中型大型火力发电机组中得到了广泛应用。采用高位收水冷却塔循环水泵后置方案,土建和设备费用均能大幅降低,具有较好的应用前景。循环水泵后置方案安全性和经济经研究,对采用同类型方案的机组具有借鉴价值。The high-level water collecting cooling tower for circulating water,featured by small drop height in rain zone and small static head of the system,has advantages such as low noise and obvious energy conservation effect.It has been widely used in large and medium-sized thermal generating units.The cost of civil works and equipment can be greatly reduced by adopting the scheme of rear circulating water pump for high-level water collecting cooling tower.Thus,this scheme has a better application prospect.Research on the safety and economical efficiency of the scheme of rear recirculating water pump is of reference value for units adopting the same type of scheme.
