600 MW机组超低排放改造引风机选型

Selection of an Induced Draft Fan after Ultra-low Emission Retrofit of a 600 MW Unit

为解决某600 MW机组超低排放改造后原引风机出力无法满足机组BMCR工况安全稳定运行的问题,对引风机实施了配套增容改造。对引风机选型过程进行了研究,并分析了改造后运行效果,结果表明改造后引风机可安全稳定运行,为同类机组的改造提供一定借鉴。

To solve the problem that the induced draft fan could not operate safely and stably in BMCR working condition after ultra-low emission retrofit of a 600 MW power unit,a matched capacity-increasing technical retrofit was conducted for the induced draft fan,while a study was carried out on the selection process,and an analysis was made on the operation performance after retrofit.Results show that the retrofitted induced draft fan can operate safely and stably,which may serves as a reference for retrofit of similar units.
