摘　　要：火电厂锅炉给水泵系统运行过程中,可能会浪费预热或者由于控制方式不合理导致能量浪费,会降低火电厂的发电效率。研究了如何通过改造系统提高给水温度从而提升脱硝入口烟气温度,实现660 MW燃煤直流炉在深度调峰情况下依然能满足环保要求,帮助火电厂提升系统运行效率,减少运行过程中的能量消耗。During the operation of the boiler feed pump system in thermal power plants,preheating may be wasted or energy wasted due to unreasonable control methods,which will reduce the power generation efficiency of thermal power plants.Study how to improve the feed water temperature through the system reform to increase the flue gas temperature at the inlet of denitrification,realize that the 660 MW coal-fired once-through boiler can still meet environmental protection requirements under the condition of deep peak shaving,and help thermal power plants improve system operation efficiency and reduce energy consumption during operation.
