直接空冷机组在我国已经大量采用,但已投运的直接空冷机组大部分都存在着由于空冷凝汽器冷却能力不够而造成机组满发背压达不到设计值的问题,作者认为空冷凝汽器传热系数和设计冷却裕量选择不准确是造成这一问题的主要原因.作者通过试验研究和大量的工程调研分析,提出了这两个关键参数指标的选择方法,供有关工程技术人员参考.

@@@@In our country Direct air-cooling units have been widely used , but the most direct air-cooling unit has been put into operation can’t reach the designed value of unit full back pressure because of air-cooled condenser cooling capacity is not enough ,The author thinks that the condenser heat transfer coefficient and the design of cooling allowance choose not accurate is the main cause of the problem. Through the experimental study and a large number of engineering research analysis, proposed the choice method of these two key parameters, providing reference for the related engineering and technical personnel.
