PARAMETRIC OPTIMIZATION AND PERFORMANCE ANALYSIS OF A REGENERATIVE ORGANIC RANKINE CYCLE USING LOW-GRADE WASTE HEAT FOR POWER GENERATION

摘要

This paper presents an analysis of regenerative Organic Rankine Cycle (ORC), based on the parametric optimization, using R-12, R-123, R-134a, and R-717 as working fluids superheated at constant pressure. A computer program has been developed to parametrically optimize and compare the system and second law efficiency, irreversibility rates of the system and their components, availability ratio, work output, system mass flow rate with increase in turbine inlet temperature under different heat source temperature conditions. The calculated results reveal that selection of a regenerative ORC during superheating using R-123 as working fluid appears to be a choice system for converting low-grade waste heat to power.
