摘要: 引风机采用小汽轮机驱动一方面可以避免电动机驱动产生的启动电流大、厂用电电压瞬间变化等问题,另一方面可以降低厂用电率、减少了能源转换过程中的各项损失,节能效果较好。以海门发电厂项目为研究案例,介绍了1 036 MW机组将增压风机与引风机合并,采用汽轮机驱动代替电动机驱动引风机的方案,重点介绍了项目技术方案、控制策略、效益分析及应用效果。以期为其他同级别火电机组引风机采用小汽轮机驱动应用提供借鉴。

Abstract: Minor turbine drive is adopted by induced draft fans, which can not only avoid large startup current caused by motor drive and instantaneous variation of auxiliary voltage, but also reduce the auxiliary service rate and the losses in the course of energy conversion with high energy-saving efficiency. Taking Haimen Power Plant for example, a scheme adopting steam turbine drive instead of motor drive with the boost fan and the induced draft fan integrated for a 1 036-MW unit is introduced, which includes the original technical scheme, the operating tactics, the investment revenue and the performance. The scheme adopting the steam-driven induced draft fan could be a reference for other thermal units of the same capacity.

Key words: thermal generation unit, induced draft fan, minor steam turbine drive, operating tactic, investment revenue, energy-saving effect
