.A 25MW Back Pressure Turbine Followed by a 30MW Secondary Set Becomes China′s First Cross Compound Extraction Condensing Turbine Set |
| |
| Abstract: | The paper reports on a 25MW back pressure turbine in one cogeneration power plant,that gets an out of standard secondary 30MW low pressure turbine generator set added,which has the main stop valve wanting,and thus becomes China′s first 55MW cross compound turbine generator set capable of running in three operation modes:pure condensing,extroction condensing as well as pure back pressure.The paper elucidates the main technical problems dealt with and presents an analysis of the economic benefits gained. |
