摘　　要：某600MW超超临界机组的回热系统采用了单壳体凝汽器,分析了该类型凝汽器的设计难点,并与常规600MW超超临界机组双壳体凝汽器的设计要求进行了对比。通过对单壳体凝汽器的结构特点分析,对单、双流程的管束布置进行比较,为单壳体、双流程、表面式结构的凝汽器设计,提供了技术参考。A single shell condenser is used in the heat regenerative system of a 600 MW ultra supercritical unit. The design difficulties of this condenser are analyzed; and the design requirements are compared with those of double shells condenser in a conventional 600 MW ultra-supercritical unit. Through the structural characteristics of the single shell condenser, the tube bundle arrangement between single pass and two pass have been compared in the paper which has provided a technical reference for the design of single shell, two pass, and surface type condenser.
