摘　　要：针对大唐潮州发电有限公司1 000MW机组一次风机运行情况进行了试验研究,结果显示一次风机裕量较大,运行效率较低。为此,将原一次风机AST-2030/1400B PP114叶型改为AST-2030/1400BPP115。改造后已运行2年,风机运行安全平稳,通过改后实际统计计算,一次风机能够实现年节电量4 892 300.00(kW·h),年节省费用252.4万元,1年即可回收投资。Test study on operation of primary air fans in 1 000 MW unit of Datang Chaozhou Power Generation Co.,Ltd.was performed.The results show the primary air fans have large margin and low operation efficiency.Thus,the original AST-2030/1400B primary air fan with blade profile of PP114 was transformed into AST-2030/1400B with blade profile of PP115.Two years running shows the air fan works stably.The annual saved electricity by the improved primary air fans can reach up to 4 892 300 （kW · h）,indicating the investment can be recovered within one year.
