Parametric analysis of the geothermal power: Dry-Steam, flash steam and hybrid cycle
The thermodynamic analysis of the geothermal power plants with dry vapor, flash steam and hybrid cycles in function to the geothermal resource conditions and the pressure of the first flash chamber was made, considering the steam quality of the last stage of expansion as operating limit constraint;...

| description | The thermodynamic analysis of the geothermal power plants with dry vapor, flash steam and hybrid cycles in function to the geothermal resource conditions and the pressure of the first flash chamber was made, considering the steam quality of the last stage of expansion as operating limit constraint; obtaining the specific work curves of the steam turbines and the temperature profiles of the binary cycle. For saturated steam configurations, the arrangement with three flash cameras presents the highest thermal and exergy efficiency, and steam turbines specific work, for example at a temperature of 200 ° C, the maximum work generated is 80.11 kJ / kg with a pressure of the first flash chamber of 6.0 bar, thermal and exergetic efficiency of 10.7% and 44.0% respectively, this is mainly due to the increase of steam enthalpy and exergy. |
