The optimization approach can start from 8 aspects including the rational reduction of the turbinebackpressure and heat loss;
设计优化途径大致可从8个方面着手，包括合理降低汽机背压，降低汽机热耗；

It is ripe in technology and doable in practice that one old condensing turbine with proper parameter is remade to be postposition turbine of the back extraction pressureturbine.
选取参数适当的旧凝汽式机组改造为背压机组的后置机在技术上是成熟的，在实际应用上也是可行的。

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