摘要
通过对某 2 0 0MW汽轮机采用三背压凝汽器运行相对于单压运行的凝结水温度、1号低压加热器抽汽量、各排汽缸最末级相对内效率及整机功率的变化情况的计算 ,定量分析了 2 0 0MW汽轮机采用三背压运行的经济性 ,并给出了2 0
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.
