| Abstract: | A calculation was conducted of the variation of parameters when a 200 MW steam turbine employs a triple back pressure condenser instead of a single back pressure one. Such parameters include the condensate temperature, the steam extraction rate of No.1 low pressure heater, the relative inner efficiency of the last stage of various exhaust cylinders and the power output of the turbine unit as a whole. On this basis a quantitative analysis was performed of the thermodynamic effectiveness of the 200 MW steam turbine employing the triple back pressure condenser. In addition, also given are the cooling water temperature requirements to be met by the above mentioned 200 MW steam turbine unit. |
