Sažetak
The paper presents steam turbine power, energy and exergy efficiencies and losses analysis during steam extractions opening/closing. The analyzed steam turbine can be used in steam power plant or in the marine steam propulsion system (low-power steam turbine). Steam extractions opening and closing can have a notable influence on various turbine operating parameters, what is currently purely exploited in the literature. Turbine developed power during steam extractions opening/closing is direct proportional to turbine energy and exergy losses and reverse proportional to turbine exergy efficiencies. Turbine energy efficiency is not affected by steam extractions opening/closing. Considering all the combinations of turbine steam extractions opening/closing, it is obtained that the range of real developed power is between 30612.91 kW and 34289.14 kW, while the range of turbine exergy efficiencies is between 85.65% and 86.08%. The range of turbine energy power losses in all possible observed combinations is between 5401.78 kW and 6050.30 kW, while the range of exergy destruction is between 4949.44 kW and 5746.81 kW.
