摘　　要：将凝汽式或抽凝式汽轮机改造成背压式汽轮机,由于排汽温度提高导致后汽缸热膨胀过大而影响汽轮机的正常运行。本文提出了一种新的改造方法,降低了后汽缸的温度,实现了改造后汽轮机的安全运行。Transforming condensing or extraction-condensing steam turbine into back-pressure steam turbine will increase the temperature of exhaust,which would cause the excessive expansion of cylinder and have impact on the normal operation of turbine.In this paper,a new approach of transformation is proposed.And it guarantees the safe operation of turbine by reducing the temperature of back cylinder.

关 键 词：凝汽式汽轮机 抽凝式汽轮机 背压式汽轮机 压力匹配器 喷水冷却装置
