摘　　要：国产超临界600 MW机组引风及脱硫增压风机由电动改为汽动的拖动方式,对改前和改后的试验结果进行计算比较,并通过经济分析得到其年收益与负荷曲线,为同容量、同类型机组提供参考。The driving way of induced draft fan and desulfuration booster fan of domestic supercritical 600 MW steam turbine is changed from electrie-driven to steam-driven, comparison of the results both before and ＇after the test is made, and through the economic analysis annual revenue and load curve is obtained, which can be used for the same capacity and units of the same type.
