In this study, to clarify the effects of heat loss on characteristics of high temperature air combustion (HiTAC), the emission of nitrogen oxide (NOx) and flammability limit in HiTAC furnace are investigated. The overall NOx production rate is found to scale with the flame temperature predicted by the modified flamelet model. The effect of heat loss on flammability limits of HiTAC are investigated at the different furnace wall temperature. The modified premixed flame model is introduced and can reproduce the flammability limit qualitatively.
