摘　　要：冷却水塔是火力发电厂循环水系统中的重要设备。纯凝式机组冷端损失是机组最大的热损失,提高冷却水塔的冷却效率,降低凝汽器循环水进水温度将提高凝汽器的换热能力,降低背压,节约发电煤耗,对机组的运行经济性有着重要的影响。冷却水塔的冷却效率则与其空气动力特性有着紧密的联系。文章以国电电力发展股份有限公司宣威分公司#9机冷却水塔的节能改造为例,就冷却水塔内风水匹配原理而采取的技术措施在冷却水塔优化改造中的应用实践作了比较详细的阐述。The cooling water tower is an important equipment of the circulating water system in fossil-fuel power station,and the cold end loss of the pure condensing unit is the largest heat loss of the unit.Improving the cooling efficiency of the cooling water tower and reducing the inlet temperature of the condenser circulating water will improve the heat exchange capacity of the condenser,reduce the back pressure,and save the coal consumption for power generation,which has an important impact on the operating economy of the unit.The cooling efficiency of a cooling water tower is closely related to its aerodynamic characteristics.This article takes the energy-saving renovation of the cooling water tower of Unit 9 in Xuanwei Branch as an example,and only elaborates in detail on the technical measures taken for the application of wind water matching technology in the optimization renovation of the cooling water tower.
