摘　　要：本文以邹县电厂四期超超临界机组工程为例,通过对大型多背压凝汽器热力特性的分析和研究,提出大型机组汽轮机冷端多背压凝汽器的设计选用的条件,积累经验,同时本文的结论也可作为其它大型机组冷端设计时的参考。The paper is based on the Project of ZouXian Electric Power Plant of the fourth stage. On the basis of the analysis and study on the thermodynamical of large multi- back pressure Condensers, the paper points out the choosing conditions in design multi-back pressure condenser of large-capacity turbine generating unit with cold junction, Accumulating experiences. The conclusion of the paper can be used as a reference of the other with large generating unit cold junction designation.
