| Abstract: | The basical situation of thermodynamic system for 300MW power generating unit in Xuanwei Power Generation Co Ltd has been presented, and the thermal efficiency obtained at present being analysed. At the same time, a fully new scheme has been put forward, and a fully new thermodymamic system being designed, the thermal efficiency of the said new system being analysed. The retrofit of unit has been carried out according to the new thermodynamic system. The thermal efficiency of unit before retrofitting was 42.55%, and after retrofitting can be 51.9%. |
