Abstract |
This paper presents a comparative exergy analysis for organic Rankine cycle (ORC) and ammonia-water based Rankine cycle (AWRC). Effects of the system parameters such as working fluid, turbine inlet pressure, and mass fraction of ammonia on the exergetical performance are systemically investigated. The results show that as the turbine inlet pressure increases, the exergy destruction ratios of source exhaust, turbine and pump increase, but those of the heat exchanger, condenser, and the coolant exhaust decrease. The component where the maximum exergy destruction occurs is the condenser in ORC but the coolant exhaust in AWRC. Index Terms - Organic Rankine Cycle, Ammonia-Water Rankine Cycle, Exergy, Exergy Destruction. | |||||||||
