Combustion behavior is significantly affected by temperature of the reactants, amount of gas recirculation and temperature of the flue gases. High temperature air combustion technology has significant impact on the design and development of advanced industrial furnaces for energy savings and materials conservation. In this technology the combustion air is preheated to very high temperatures using regenerative burners. Experimental and theoretical studies are underway for determining the structure of flames using high temperature combustion air. Specifically information on ignition and flame stability, chemical kinetics, flame spectral characteristics, turbulence, flame chemistry, heat flux distribution from the flame is being obtained. The objectives of this paper is to provide fundamental understanding on the physical and chemical processes and optimal utilization of the technology for some specific application.
