摘　　要： 为解决空冷发电厂夏季高背压运行影响汽轮机安全的问题,保证机组的出力,可以对直接空冷机组加装尖峰冷却装置,以提高直接空冷机组迎峰渡夏能力。就此介绍了华能榆社电厂300 MW机组尖峰冷却器系统改造,并针对夏季高温时段不同负荷、不同环境温度下,投运尖峰冷却装置后机组经济性的变化进行了对比分析,最后对机组取得的经济效益进行了评估。 In order to solve the influence of steam turbine air cooling power plant during high pressure operation problems, ensure the output capacity of the unit, the direct air cooling unit with peak cooling in order to improve the device,direct air cooling unit peak summer ability. This transformation peak cooling system in Huaneng Yushe power plant 300 MW unit, and in the summer high temperature period in different load, different environment temperature The economic changes of the unit after being put into operation are compared and analyzed. Finally, the economic benefits obtained by the unit are evaluated.
