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
