摘　　要：采用数值方法对大港电厂从意大利引进的３２８ＭＷ汽轮机凝汽器壳侧的流动与传热过程进行了计算，对该凝汽器的设计合理性进行了分析。结果表明，该凝汽器的管束布置具有一定的合理性，但也有需改进之处，凝汽器的工作压力可能会因此而略高于设计压力。By the use of a numerical method calculated was the flow and heat transfer process on the condenser shell side of a 328 MW steam turbine condenser imported from Italy.An analysis is given of the rationality of the condenser design.The results of the analysis show that the layout of the condenser tube bank features rationality in certain aspects but there is room for improvement.Hence,the operating pressure may be slightly higher than the design pressure.
