As the oxygen concentration decreases in high temperature air combustion of kerosene, the size of combustion flame becomes larger and larger, and the local region at high temperature decreases. The existing region of chemical species, OH, CH, and C_2 radicals, observed in the combustion flame becomes larger and larger and the local region with strong emission intensity decreases. Namely, uniform temperature profile and uniform distribution of chemical species were confirmed under the condition of high temperature air combustion, which leads low NOx combustion. The effect of carbon dioxide on the homogeneous distribution is stronger than that of nitrogen, because carbon dioxide has a larger specific heat value than nitrogen.
