Energy and Exergy Analysis of Dieng Geothermal Power Plant

Energy and exergy analyses are conducted at the Dieng Geothermal Power Plant to determine energy loss of components by calculating efficiency, rate change in flow, each component. The data were collected on component, including production wells, turbines, main condenser, inter-condensers, cooling towers, with collection occurring from April 2017 March 2018. begin enthalpy entropy both input output compiled temperature data, help a steam table. study results show that lowest efficiency was 67% turbine, highest seen 5.8×104 kW, inter-condenser. In addition, greatest 50 Mw, which occurred indicating it component most need repair. summary, clarified needed be treated repaired turbine.
