At present heat rate calculate of the double backpressureturbine is according to single backpressureturbine, which brings deviation of heat rate calculate.
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。

Here an example is: heating the feedwater of condensing turbine by exhaust steam of a backpressureturbine (through tubular steam cooler) to raise the set's heat economy.
介绍一例：利用管式蒸汽冷却器将背压机排汽加热凝汽机给水，从而提高机组热经济性。
