Abstract
The organic Rankine cycle (ORC) and the ammonia-water based power generating cycle are considered as the most feasible methods for recovery of low-grade finite heat sources. This paper presents a comparative exergetical performance analysis for ORC with regeneration (ORCR) and ammonia-water Rankine cycle with regeneration (AWRCR). Effects of the system parameters such as working fluid, turbine inlet pressure, and mass fraction of ammonia on the exergetical performance are parametrically investigated. Results show that AWRCR does not show higher exergy efficiency than ORCR, however, shows lower exergy destruction ratio of source heat exchanger than ORCR. Index Terms -Organic Rankine cycle, ammonia-water Rankine cycle, regeneration, low-grade heat source.
