摘　　要：采暖季中供热机组将汽轮机五段抽汽直接作为采暖抽汽,这样容易造成大量差压能损失。为了更好地利用差压能,减少能量损失,可以利用超低压汽轮机直接拖动供热循环泵的方法,降低厂用电率。通过对实际电厂供热系统改造方案的研究,使用超低压汽轮机技术可以充分对能量梯级利用,提高能量利用率,并达到很好的经济收益。Heating season heating unit five sections of the turbine extraction steam directly as heating steam extraction,which can easily lead to the loss of a large number of differential pressure.In order to make better use of the differential pressure can reduce energy loss,you can use ultra-low pressure steam turbine cycle heat pump directly drag method to reduce power consumption rate.Through the study of actual plant heating system rehabilitation programs,the use of ultra-low pressure steam turbine technology can take the energy cascade utilization,improve energy efficiency and achieve good economic returns.
