摘　　要：以供电煤耗率作为机组运行经济性评价指标,对600MW火电机组给水泵小汽机驱动方式和电动驱动方式的运行经济性进行了计算比较。结果显示配有新型高效液力偶合器的电动驱动方式在运行经济性上较小汽轮机驱动方式具有明显的优势。By using the index of coal consumption rate of power supply as the evaluation criterion,the operational economy of small turbine driven way and motor driven way for feed-water pumps of 600 MW thermal power units was calculated and compared.The results showed that compared to the small turbine driven way,the motor driven way with high-efficiency hydraulic couplers is more advantageous.
