Second law analyses on oxy-fuel combustion of gaseous fuels
The exergy losses in the adiabatic premixed oxy-fuel combustion are quantitatively analysed. The global exergy loss decreases with increasing equivalence ratio. The exergy loss of chemical reaction is comparable to that of internal thermal energy exchange for low equivalence ratio while that of mixing process is negligible. To keep similar thermodynamic characteristics of conventional combustion, ...
