The largest exergy loss comes from the combustion processes in the combustion systems such as gas turbines. The flow with the chemical reactions involves four irreversible processes of the viscosity, heat conduction, mass diffusion and chemical reaction. The source of the exergy loss during the combustion can be evaluated by analyzing the entropy generation of each process. In this study, we analyzed the entropy generation of four processes and the exergy loss in the one-dimensional laminar premixed flames. It is noted that the chemical reactions are responsible for the major exergy loss. The contribution of the heat conduction is significant, but less than that of the chemical reaction. An increase in the inlet flow temperature reduces the exergy loss, while a decrease in the equivalence ratio increases the exergy loss.
