Abstract

In this research, the thermo economic analysis of a PSOFC/GT hybrid cycle was taking place regarding a sustainable approach. Initially, the proposed cycle was accurately introduced and then the modeling methodology was presented. Furthermore, the cycle simulation was presented with the development of a thermodynamic model in EES software based on the mass, energy and economic equations, those were solved simultaneously. With introducing electrical and overall efficiencies, a comprehensive analysis of thermodynamics was done, which was contributed to a dynamic economic model, which was proposed and analyzed in after-steps. In order to determine effects of change in main parameters, a parametric study was prepared. By these means, the results show that the electrical efficiency of 61.3 % and overall efficiency of 77.65 % are achievable within 1962 kW net output power, where, HRSG heat recovery capacity is equal to 436.8 kW and HPR was calculated 22.27 %. This cycle with producing 310.9 g/kWh CO2, reduces the CO2 emissions by 30.3 % comparing with the conventional gas fired combined cycles.
