摘　　要：将湿冷机组部分凝结水引入空冷机组乏汽管道,升温后等量凝结水回到湿冷机组,从而达到降低空冷机组背压、增加乏汽利用率的效果,同时减少湿冷机组末级抽汽,降低发电煤耗。该系统具有极强的可操作性和推广前景,实现了燃煤电厂的深度节能,提高电厂经济性。Introduced part of the condensate of the wet-cooling unit into the exhaust steam pipes of the air-cooling unit,and the same amount of condensate returned to the wet-cooling unit after heating,so as to achieve the effect of reducing the back pressure of the air-cooling unit and increasing the exhaust steam utilization rate.At the same time,it reduces the final stage steam extraction of the wet-cooling unit and reduces coal consumption for power generation.The system has strong operability and promotion prospects,realizes the deep energy saving of coal-fired power plants and improves the economic efficiency of the power plants.
