Abstract

High Temperature Air Combustion is a recent development in the combustion of hydrocarbon fuels which promises high efficiencies. The principal feature of HiTAC is combustion at extremely low oxygen concentration levels with air preheating to high temperatures to maintain stable combustion. Experiments show that, under these conditions, the flame volume expands and the peak temperature decreases. In the present paper, these features of High Temperature Air Combustion are simulated in a 300 kW natural gas burner. Simulation was done by varying the operation condition such as oxidant temperature and the inlet oxygen concentration. The oxidant temperature was varied at 300K, 600K, 900K, 1200K and 1500K. The oxygen concentration was varied at 5%, 15% and 21% by wight. The results of the simulation is validated by comparing the predictions with the measured values under normal combustion conditions.
