A Thermodynamic Analysis of Low-Temperature Heat Recovery for ORC Power Plants

E. Fanelli, D. Marano, A. Viggiano, G. Braccio & V. Magi
In the last years, increasing interest has been addressed towards Organic Rankine Cycle (ORC) power plants as a consequence of their potential integration with low¬grade heat sources. Available thermal heat sources are solar energy, geothermal energy, biomass, and waste heat from various thermal processes such as heat from exhaust gases of internal combustion engines. In this work, a low-temperature geothermal source (below 100 °C) has been considered, and an accurate thermodynamic analysis has been performed...
