摘　　要：对凝汽器、循环水泵为主的冷端系统设备的出力能力进行评估,根据汽轮机增容改造后对冷端系统设备的要求,分析计算出增容改造后冷端系统设备应具备的出力能力,并提出对应设备的改造范围、改造关键点、关键部件的选型原则,以及对比改造前后的效果。To satisfy the uprating requirement of a steam turbine, an evaluation was conducted on the capacity of its cold end equipment, such as the condenser and circulating pump, etc., together with a calculation on the capacity that the cold end equipment should have after uprating of the steam turbine. On above basis, the range and key points of the retrofit as well as the selection of corresponding equipment were proposed, while a comparison was made simultaneously on economic efficiency of the unit before and after the retrofit.
