چکیده
Abstract In this study, the performance analysis of waste heat recovery systems in a power generation system consisting 13000 Proton Exchange Membrane Fuel Cells (PEMFC) stack has been investigated. Organic Rankine Cycle (ORC) and Kalina System 11 (KCS11) as bottoming cycles to convert generated into electricity were compared with each other defined hybrid system. The improvement an exact energy exergy after utilizing analyzed. Results show that efficiency combined using increase by about 5% 1.75% respectively. addition, results indicate increases 4% 1.5% total destruction rate obtained for is 235.5 kW when ORC used 329.7 KCS11 presented higher efficiencies than but different working fluids equipment must also be considered from economical point view.

The energy and exergy analysis of a novel cogeneration organic Rankine power and two-stage compression refrigeration cycle
The energy crisis in recent years has led to the use of thermodynamic cycles that work based on renewable energies. Low-temperature cycles—such as organic cycles—are suitable strategies for the application of renewable energies. The present study proposes a novel cycle through the integration of a two-stage compression refrigeration cycle with a combined Rankine power and ejector refrigerat...
متن کاملExergy Analysis of a Novel Combined System Consisting of a Gas Turbine, an Organic Rankine Cycle and an Absorption Chiller to Produce Power, Heat and Cold
The current work investigates the exergy analysis of a new system to generate power, heat, and refrigeration. In the proposed system, the heat loss of a gas turbine (GT) is first recovered by a Heat Recovery Steam Generator (HRSD), then by an Organic Rankine Cycle (ORC) to generate warm water and additional power, respectively. In the ORC, reheating is used to increase the output power, the req...
متن کاملEngine Load Effects on the Energy and Exergy Performance of a Medium Cycle/Organic Rankine Cycle for Exhaust Waste Heat Recovery
The Organic Rankine Cycle (ORC) has been proved a promising technique to exploit waste heat from Internal Combustion Engines (ICEs). Waste heat recovery systems have usually been designed based on engine rated working conditions, while engines often operate under part load conditions. Hence, it is quite important to analyze the off-design performance of ORC systems under different engine loads....
