摘　　要：随着节能降耗的深入推进,某电厂3号、4号机组在引风机、脱硫增压风机合并后的基础上,采用汽轮机代替电动机驱动引风机。对炉膛负压控制策略、特殊管路配置、风机并列实验、异常工况分析等进行分析探讨,证明汽轮机驱动式引风机的创新型设计、可控性试验成果。研究成果对大型电厂辅机选型、调试、运行、改造等多方面都具有较大的参考价值。With further promotion of energy saving,the induced draft fan merges with the desulfurization booster fan in No.3 and 4 units of a power plant,and the fan is driven by turbine instead of the electric motor.The control strategy of furnace draft,special plumbing configuration,parallel tests for fans and abnormal condition analysis are discussed in this paper,proving that the fan driven by turbine is innovative and controllable.It provides references and is worth while popularizing its application from the type selection,debugging,running and refomation of auxiliary engines in large-scale power plant.
