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。

Abstract

Test study on operation of primary air fans in 1 000MW 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.
