Propane gas (C3H8) at 25C, 1 atm enters an insulated reactor operating at steady state and burns completely with air entering at 25C, 1atm. Plot the adiabatic flame temperature versus percent of theoretical air ranging from 100 to 400%. Why does the adiabatic flame temperature vary with increasing combustion air? Note: Just pick one or two AFR's, 2125 K for 120% Theoretical Air
