Sažetak
This paper presents an energy and exergy analyses of two steam turbines from geothermal double flash power system. Along with the calculation of efficiencies and losses, in the exergy analysis is performed variation of the ambient temperature to investigate its influence on the obtained results. Low pressure turbine (LPT) produces higher real mechanical power in comparison to high pressure turbine (HPT) (35793.89 kW of LPT and 20111.21 kW of LPT) dominantly due to higher steam mass flow rate which expands through LPT. Energy and exergy efficiencies of both observed turbines are around 90% what are high efficiencies for the turbines which dominantly operates by using wet steam. An increase in the ambient temperature increases exergy loss and decrease exergy efficiency of both observed steam turbines.
