Energy and exergy analysis of biogas fired regenerative gas turbine cycle with CO2 recirculation for oxy-fuel combustion power generation

In this paper, thermodynamic performance of oxy-biogas regenerative gas turbine cycle with CO2 recirculation is evaluated. The CO2 stream is split into the primary and dilution zones. In the primary zone, chemical-equilibrium-model is applied for exergy analysis. Influences of relevant parameters—CO2-to-O2 molar ratio (CtO) in the primary zone and primary diluent ratio (PDR)—on the temperature of combustion chamber (CC) and turbine, net produced...
