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。

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 pressure turbine.

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。

Here an example is: heating the feedwater of condensing turbine by exhaust steam of a back pressure turbine (through tubular steam cooler) to raise the set's heat economy.
