The change in exergy efficiencies and losses of low-power steam turbine with steam extractions at three loads

An exergy analysis of low-power steam turbine with three steam extractions from cogeneration power plant is performed in this paper. The turbine is analyzed at three different loads. The most dominant exergy flow stream from the analyzed turbine is a steam stream at the turbine inlet, at all observed loads. Turbine developed power at low, middle and high load is equal to 25271.92 kW, 28474.22 kW and 28623.19 kW, respectively. An increase in turbine load resulted with a continuous increase in turbine exergy destruction (from 3378.67 kW at low turbine load to 4112.92 kW at high turbine load), while the same increase in turbine load resulted with a continuous decrease in turbine exergy efficiency (from 88.21 % at low turbine load to 87.44 % at high turbine load).
