摘要
Abstract
Taking a 2×1 000 MW unit in northern China as an example,the basic configuration parameters of the natural ventilation direct air cooling system and the surface condensing indirect air cooling system are given,and the technical and economic comparison of the two air cooling systems is made.The results show that:in the technically,the natural ventilation direct air cooling system has a lower operating back pressure when the temperature is high.In the economically,the initial investment of natural ventilation direct air cooling is high,but the annual operating cost(including coal consumption)is low,and it has a good payback period.Finally,combined with the characteristics of natural ventilation direct air cooling system and the winter operation experience of the operation units,the effective measures for antifreeze and reducing the subcooling degree of condensate of natural ventilation direct air cooling system are given.关键词
