摘　　要：介绍了凝汽器总体传热系数和实际清洁系数的计算方法。以某核电机组为例,计算并研究了在不同冷却水温度、冷却水流量、凝汽器热负荷条件下凝汽器清洁系数对机组出力的影响。结果表明:在南方地区或带基本负荷的核电机组上,应尽量提高凝汽器清洁系数;在评估大修后的凝汽器性能时,应注意冷却水温度的变化及方向。The calculation method of the overall heat transfer coefficient and the actual cleanliness coefficient of the condenser is introduced.Taking a nuclear power unit as an example,the influence of the condenser cleanliness coefficient on the unit output under different cooling water temperatures,cooling water flow rates,and condenser heat load conditions is calculated and studied.It is proposed that the condenser cleanliness coefficient should be increased as much as possible in the southern region or nuclear power units with basic load.It is pointed out that when evaluating the performance of the condenser after overhaul,attention should be paid to the change in the size and direction of the cooling water temperature.
