摘　　要：通过理论分析 ,得出考虑传热系数随凝汽器结构和冷却水入口温度变化条件下多背压凝汽器的平均冷凝温度的关系式 ,分析了各级传热面积和循环倍率对平均冷凝温度的影响 ,并以多背压凝汽器的平均冷凝温度为目标函数 。Through a theoretical analysis the authors have derived a relationship for calculating the mean condensation temperature of a multi-pressure condenser, which has taken into account the variation of heat transfer factor with the change of condenser construction scheme and cooling water inlet temperature. Analyzed is the influence of the heat transfer area and the circulation ratio of various stages on the mean condensation temperature. Moreover, with the mean condensation temperature of the multi-pressure condenser serving as a target function an optimized construction of the condenser has been worked out.
