摘　　要：文章介绍了燃机单循环电厂循环冷却水温对机组出力的影响,结合尼日利亚某燃机工程实例,对机械通风冷却塔、闭式冷却塔、海勒型辅助冷却器3种循环冷却水系统方案进行了技术经济性分析,并说明了各系统的适用环境条件。The effects of circulating cooling water temperature of single cycle gas-turbine on unit output are explained. Using a Nigeria project as an example, technical and economic analysis of 3 circulating water cooling system schemes, namely, mechanical draft cooling tower, closed cooling tower,and Heller auxiliary cooler, are performed. Applicable environment conditions for each system are also explained.
