摘要: 为节能减排,提高能源利用效率,华能海门电厂1 036 MW超超临界机组对全厂功率最大设备引风机进行技术创新,在国内首次将引风机由常规的电机驱动改为汽轮机驱动,并将引风机和增压风机合并设置,不再单独设置增压风机,采用此方案后明显降低了厂用电率,减少了6 kV大电机启动对厂用电系统的冲击,引风机可实现变速调节,减少节流损失,节能效果显著。汽轮机驱动引风机运行稳定,调节炉膛负压功能良好,能满足满负荷运行时对引风机性能指标的要求。

Abstract: For energy-saving and emission-reducing, enhancing the efficiency of energy utilization, the technological innovation for induced draft fan with the maximum power in 1 036 MW ultra supercritical unit of Huaneng Haimen Power Plant was implemented. Changing general motor-driven induced draft fan to turbine-driven mode for the first time, merger setting the induced draft fan and the FGD booster fan, not setting FGD booster fan alone, the power plant using electricity rate was obviously reduced. And 6 kV power of the auxiliary power system was reduced. The induced draft fan can realize variable speed adjustment, and the loss of throttling was reduced, the energy-saving effect was remarkable. The operation of the induced draft fan driven by turbine was stable, the function of furnace pressure adjustment was good, and which can satisfy the index request of induced draft fan performance under full load condition.

Key words: ultra-supercritical, induced draft fan, turbine driven, energy-saving
