The purpose of this simulation study is the examination a solar-driven power cycle that driven by collectors with evacuated tubes. an organic Rankine (ORC) works cyclopentane. novelty use reheating in order to enhance its thermodynamic efficiency, while also has recuperator. Moreover, compared conventional ORC determine performance enhancement examined idea. analysis done developed program Engi...

In this study, two systems are brought forward to recover the waste heat of a proton exchange membrane fuel cell (PEMFC), which are named the organic Rankine cycle (ORC), and heat pump (HP) combined organic Rankine cycle (HPORC). The performances of both systems are simulated on the platform of MATLAB with R123, R245fa, R134a, water, and ethanol being selected as the working fluid, respectively...

As global industry developed rapidly, the energy demand also rises simultaneously. In the production process, there’s a lot of energy consumed in the process. Formally, the energy used in generating the heat in the production process. In the total energy consumption, 40% of the heat was used in process heat, mechanical work, chemical energy and electricity. The remaining 50% were released into ...

The subject of this analysis is a solar power/cooling system based on a novel hybrid steam Rankine cycle. Steam is generated by the use of solar energy collected at about 100°C, and it is then superheated to about 600°C in a fossil-fuel-fired superheater. The addition of about 20-26 percent of energy as fuel doubles the power cycle's efficiency as compared to organic fluid Rankine cycles operat...

the present paper is aimed at describing a “closed cycle” power plant schematic (soft, solar oxygen fuel turbine) with macroalgae (seaweed) cultivation in a pond, combustion of its organic matter in a fluidized bed boiler of rankine cycle and return of the combustion products to the pond to feed algae. the oxygen used for combustion is released to atmosphere in photosynthesis. as a renewable fu...
