Abstract:   (15208 Views)
SOFC-GT cycle coupled with a steam generator is investigated in this paper through the exergy analysis. Chemical and electrochemical simulation of SOFCs and thermodynamic and exergy models of other components are discussed and results are compared with a GT-Steam generator cycle. Based on simulation results Exergy efficiency of SOFC-GT- Steam generator is higher than conventional GT-Steam generator cycle. Furthermore parametric study is performed and results are presented. Parametric study shows that stack temperature and compressor pressure ratio can increase the efficiency but cell current density and TIT decrease the efficiency. Increase in steam pressure and decrease in Pinch Point, will increase the exergy efficiency.
