摘要： 针对一2×600 MW 直接空冷机组夏季高温时段背压高、煤耗高的现状，借鉴直接空冷机组的改造经验，将中
水作为尖峰系统的补水，达到了降低机组运行背压、提高机组夏季发电负荷、降低煤耗的目的，同时评估了改造后机组
的经济效益。

Abstract: In view of the high back pressure and coal consumption of a 2×600 MW direct air cooling unit in the high temperature
period in summer, this paper used the transformation experience of the direct air cooling unit for reference, took the reclaimed
water as the water supplement of the peak system, achieved the purpose of reducing the unit operation back pressure, increasing
the unit summer power generation load and reducing the coal consumption, and evaluated the economic benefits of the unit after
transformation.

Key words: direct air cooling unit; peak cooling system; unit operation back pressure; economic benefits
