600MW火电机组引风机和增压风机合并改造分析

Analysis on reformation of merging of induced draft fan and booster fan for 600MW thermal power unit

以华能铜川照金电厂一期2台600MW燃煤发电机组为例,分析了"引增合一"技术改造方案,比较了改造前后的经济性,以及厂用电率的变化情况。改造后,引风机运行稳定,达到了预期改造目标。

Taking two 600 MW coal-fired power units of Huaneng Tongchuan Zhaojin Power Plant project phase I as example,the technical reformation scheme of'merging induced draft fan and booster fan'was analyzed. The economical efficiency and the auxiliary power rate of the units after reformation were compared with those indexes of the units before reformation. After the reformation,the induced draft fan operates stably,and the expected reformation goal was achieved.
