摘　　要：基于国内多个间接空冷电厂在实际运行中遇到的防冻问题,从设备选型、控制系统及实际运行等方面分析了空冷散热器管内发生冰冻现象的原因。结合我国"三北"地区的气象特点,提出可供SCAL型间接空冷系统采用的设计和运行方面的防冻措施,为SCAL型间接空冷系统在"三北"地区的应用提供了防冻技术支持。Based on the practical anti-freezing problems of indirect air-cooling system in several domestic power plants, the freezing phenomenon occurred in air-cooled radiator tube was analyzed from the aspects of equipment selection, control system and actual operation. Combined with the meteorological features in north China, northeast China and northwest China regions, some anti-freezing measures were proposed for the design and operation of SCAL indirect air-cooling system, which could provide technical supports for the application of SCAL indirect air-cooling system in north China, northeast China and northwest China regions.
