摘　　要：陡河电厂2台日本日立公司250MW亚临界压力机组,由于引风机影响出力进行了2次改造,第2次改造采用的是国产化引风机,实际运行表明改造后的引风机性能稳定、耗能大幅度降低,为引风机采用变速调节,进一步发挥风机节能的潜力创造了有利条件。Two Japanese Hitachi made250MW subcritical pressure generating units in Douhe Power Plant were retrofitted two times owing to derating resulted from the influence of draft fans.In the second time retrofit,the in-digenous induced draft fans were adopted.The practical operation shows that the indigenous induced draft fans can run stably,with energy consumption greatly reduced and creating favorable conditions for employing variable speed control to further take advantage of energy-saving potential of draft fans.
