The use of the organic Rankine cycle (ORC), flash (OFC) and Kalina (KC) is proposed to enhance electricity generated by a supercritical CO2 recompression Brayton (SCRB) cycle. Novel comparisons SCRB/ORC, SCRB/OFC SCRB/KC integrated plants from thermodynamic, exergoeconomic sustainability perspectives are performed choose most appropriate bottoming for waste heat recovery SCRB For comprehensiven...

Excessive heat losses and water consumption in cooling units are significant constraints restricting the application circumstances performances for SCO2 Brayton cycle, exchange capacity precooler (PRC) is typically 1.5 times that of power generation. Therefore, this research offers a high-integrated combined power/cooling system which two waste exchangers (WHEs) rectifier (RET) used instead PRC...

Abstract A competitive advantage for the molten carbonate fuel cell (MCFC)-driven energy processes is their versatility. On other hand, since MCFC consumes carbon dioxide, it can reduce amount of dioxide emissions compared to cells. Accordingly, current paper develops and evaluates thermodynamic, exergoeconomic environmental analysis a new hybrid process (HEP) based on reformer stack biomass ga...

Integrated solar-assisted polygeneration systems have emerged as an effective and sustainable alternative for meeting thermal, power freshwater demands through decentralized generation. In this framework, study introduces a new design dynamic simulation approach to solar energy-driven system integrating gas steam turbine cycles, organic Rankine cycle (ORC), CO2 capture, humidification-dehumidif...

Abstract In this paper, the Chinese Fusion Engineering Testing Reactor (CFETR) power conversion system, with a supercritical CO 2 (SCO ) Brayton cycle, is designed, analyzed and optimized. Considering pulse operation of reactor, heat storage loop high temperature molten salt low concrete introduced. Based on parameters first cooling loop, CFETR designed studied. A new SCO cycle for dual sources...
