摘　　要：为减少厂用电、提高机组效率,结合北仑电厂百万kW级超超临界机组的实际情况,提出并详细论述锅炉引风机采用回热式背压汽轮机驱动的方案,对工程的技术经济性进行了分析。此方案可为大型机组的节能减排提供借鉴,同时,为火电厂驱动用汽轮机的推广应用提供一定的思路。In order to reduce auxiliary power consumption and improve the unit efficiency, a scheme is proposed and analyzed that the steam turbine is used to drive the induced draft fan （IDF）. Based on the phase-3 Beilun Power Plant, the technology and economy and some conclusions are achieved, which can provide a reference for relevant engineering design.
