C12-4.9/0.981型汽轮机实施双功能(抽凝式与背压式)汽轮机改造

Implementation of Type C12-4.9/0.981 Steam Turbine Reconstruction of Double Function(Condensing and Backpressure Type) Turbine

许多配备抽凝式汽轮机的小热电站迫于无奈,将抽凝式汽轮机拆除,重新购置背压式汽轮机取而代之。此过程中,一方面由于两种型式汽轮机的差异太大,造成了大量设备处在闲置状态,大量资金沉淀;另一方面,背压机的发电汽耗太大,有时出现背压机的电功率不能满足厂用电的状态。

Many small thermal power stations equipped with a condensing turbine are forced to remove the condensate turbine and replace the back pressure turbine instead. On the one hand, in this process, because of the difference of the two types of steam turbine is too large, resulting in a large number of equipment is in the idle state, precipitated a lot of money; on the other hand, the power consumption of the backpressure machine is too large, sometimes the power plant can not meet the electrical state of back pressure machine.
