Show 15 mixture, the flame temperature, becomes higher than the adiabatic flame temperature. This lead to the lean combustion in the outside of the lean limit of inflammability. (3)The diffusion layer becomes thinner with the increase of the strain rate. The maximum of the temperature decreases with the strain rate. The N 0 X and other species (NO, NO2) formation is reduced by the strain rate of the air stream. (4) With the range of the flame temperature from 1300 K to 1625 K, NOx is nearly constant, which means that the NOx is independent of the flame temperature. The weak temperature dependency is inherent in the prompt NO. Therefore, within the low temperature range, prompt NO is predominant. (5)The overall reaction rate in the present burner, agrees with the Arrhenius plot. The estimated activation energy is 380 kJ/kmol. REFERENCES (1) Sobiesiak, A., Rahbar, S. and Becker, H.
