目前双背压汽轮机是按单背压汽轮机来进行热耗率计算的,由此带来热耗率计算的偏差。
At present heat rate calculate of the double back pressure turbine is according to single back pressure turbine, which brings deviation of heat rate calculate.
Selection methods of back pressure turbine according to after-heat are introduced. An example is given to show economic advantages of differential pressure power generation using heating steam.
