A comparative study and sensitivity analysis of different ORC configurations for waste heat recovery

The paper aims to assess the performance of three different Organic Rankine Cycle (ORC) configurations from thermodynamic and economic standpoints. The examined configurations include: Basic ORC (B-ORC), Reheating ORC (RH-ORC) and Regenerative ORC with an open feed-heater (REG-ORC). Four different w...

The examined configurations include: Basic ORC (B-ORC), Reheating ORC (RH-ORC) and Regenerative ORC with an open feed-heater (REG-ORC).
