摘要
论述了多压凝汽器的特点及节能原理，分析了多压凝汽器在２００ＭＷ机组中的应用前景，设计了三压凝汽器，进行节能效果计算，并探讨了已投运的２００ＭＷ机组的凝汽器改为三压的可行性。结果显示：在高水温地区或用冷水塔的２００ＭＷ机组使用三压凝汽器可以提高机组的的经济性。
Described in this paper are the specific features of a multi-pressure condenser and its energy-saving fundamentals. An analysis is given of the application prospects of such condensers in 200 MW units. A triple-pressure condenser has been designed with its energy-saving effectiveness calculated. In addition, the authors also discussed the possibility of modification of a condenser to triple-pressure for a 200 MW unit currently in operation. It is shown that the use of triple-pressure condensers in a region with a high water temperature or in the case of a cooling tower being employed can lead to an enhanced economical operation of the power plants.
