摘　　要：为了减少厂用电,提高机组效率,提出了引风机采用汽轮机驱动的方案,并对采用背压式汽轮机和凝汽式汽轮机2种系统设计进行了分析。同时结合华能沁北发电厂三期工程,将2种汽轮机方案与电动驱动方案进行了技术经济比较,得出了相关比较结论,给相关的工程设计提供参考。In order to reduce auxiliary power consumption and improve the unit efficiency, a scheme is proposed that the steam turbine is used to drive the induced draft fan （IDF）. An analysis is conducted on the design of two systems in which back pressure stream turbine and condensing turbine are adopted respectively. Based on the phase-3 Huaneng Qinbei Power Plant, two steam-driven and motor-driven schemes are compared in terms of technology and economy and some conclusions are achieved, which can provide a reference for relevant engineering design.
