摘要
空冷机组是“富煤少水”地区或干旱地区建设火力发电厂的最佳选择。现简要介绍3种类型空冷系统的运行特性,对直接空冷系统和海勒式间接空冷系统进行了比较,提出了运行中存在的几个问题,如机组运行背压、真空严密性、防冻等,并对此提出了相关建议。
Air cooling unit is the best choice for thermal power plant in area which is rich in coal and poor in water or in drought areas. The operation characteristics of three kinds of air cooling system are presented. A comparison was made between direct air cooling system and Heller indirect air cooling system. Problems were pointed out such as backpressure in unit operation,vacuum tightness and anti-freezing,meanwhile suggestion was proposed.
