摘　　要：国内600 MW及以上的火电机组汽轮机,绝大多数采用双背压设计,但其中多数机组抽汽管道系统设计不合理,低压凝汽器端差显著增加,造成不应有的能损。重点介绍了目前常见的抽空气系统,分析了端差增加的机理,给出了解决方法和节能潜力。For thermal power units in China with capacity of 600 MW and above,most of the unit use dual pressure condensers, but most of the unit system of the stream extraction pipeline design is not reasonable,low pressure condenser end increased significantly,can be caused by loss.It is mainly introduces the common air extraction system,analyzes the difference increases the mechanism,and put forward the solutions and energy-saving potential.
