摘　　要：冷却水侧的结垢现象会增加冷却水的压降,降低设备的换热性能。文章根据一例因冷却器换热性能下降而导致的发电机无法正常运行的问题,计算分析了结垢对发电机气体冷却器的影响,并验证了计算分析的准确性。Fouling in cooling water side is resulted in pressure drop increased and thermal performance reduced.Fouling effects on the generator gas cooler is calculated and analyzed based on the problem that a generator is unable to operate normally,caused by the reduction in thermal performance of gas coolers while the accuracy of calculation and analysis are verified.

关 键 词：气体冷却器 结垢 换热性能 压降
