摘　　要：叙述了小型凝汽或抽凝机组改造成背压机组的方法及小型机组应用热泵改造的实例。改造后的机组与凝汽和抽凝机组运行方式相比较,仅发电一项,年节约标煤分别为6 600 t以上和5 100 t以上。Methods are presented for the revamp of small-sized condensing turbine or bleeder tur- bines to back-pressure turbine and an example is given of the revamp of a small set with the use of a heat pump. The revamped set, compared to the condensing and bleeder turbine, saves annually over 6 600 t and 5 100 t of standard coal.

关 键 词：凝汽汽轮机 抽凝汽轮机 背压机组 热泵 改造
