摘　　要：为提高燃煤直接空冷机组的经济性,提出了空冷机组夏季高温期设置尖峰冷却系统的方案;并对各种尖峰冷却方案进行了对比,重点探讨了带蒸发式凝汽器的尖峰冷却系统与带表面式凝汽器的尖峰冷却系统的技术及经济的差异。研究表明,带表面式凝汽器的尖峰冷却系统初投资低、技术成熟稳定;年运行耗水量及净收益相差不大。In order to improve the economy of the direct air cooling unit,a scheme of setting the peak cooling system in summer high temperature period is put forward.The technical and economic differences between the peak cooling system with evaporative condenser and the peak cooling system with surface condenser are discussed.The results show that the peak cooling system with surface condenser has low initial investment,mature and stable technology.Annual operating water consumption and net income are similar.
