摘要
详细阐述了单压凝汽器如何获得最佳真空，揭示了在单压凝汽器相同的运行条件下，采用双压凝汽器其热效率高于单压凝汽器的规律和原因；并分析了在不同的循环冷却水进水温度，循环水温升的条件下双压凝汽器较单压凝汽器的受益情况．
In this paper,which elaborated on how the single-pressure condenser's optim -um vacuum is obtained.It revealed the law and reason that the efficiency of the double pressure condenser is higher than that of the single-pressure one at the same condition as the operation of a single pressure-condenser and it also analysed the benefit from the double-pressure condenser at the condition of the different circulating cool water temperature and the different circulating cool water temperature rise.
