Recent development of the regenerative combustion system, in which ceramic honeycomb is used as a heat storage medium in a regenerator, has raised preheated air temperature up to 1,600 K. By preheating the combustion air, the heating potential of the furnace gas is increased and the fuel consumption is reduced dramatically. However, higher air temperature increases the potential of NOx formation. Therefore, to apply this technology for commercial use, development of low NOx burner is strongly requested. In this paper, newly developed low NOx burner as well as the high performance honeycomb regenerator is explained. Also, theoretical and numerical analysis of fuel saving by the high preheated air combustion is discussed.
