摘要：The reaction of thermal NO X is highly sensitive to temperature and if the technique can reduce the flame temperature it would be effective to reduce NO X formation. Flue gas recirculation can reduce the flame temperature and as a result decrease the rate of NO X formation. In the present study the effect of FGR on NO X emission in the premixed methane-air mixture is investigated numerically and experimentally. The experiments are carried out in an axial symmetry cylindrical combustion chamber for a range of equivalence ratio and different percent of FGR. The numerical simulations are conducted simultaneously, using Premix code of Chemkin package. The GRI-Mech3.0 mechanism is used for the combustion of methane. The results reveal that as the percentage of flue gases is increased, the flame temperature and NO X are decreased. This is because of the presence of species with high thermal capacity in flue gases.
