Abstract A new type of 10w-NOx burner was studied for application of a regenerative burner system in an industrial furnace. The fuel is separately injected at an angle to the axis of the air stream. Thus mixing of fuel and air is suppressed at the initial stage of combustion, and combustion progresses gentIy. ConsequentIy, very uniform combustion is obtained, self-recirculation of the flue gas is achieved. and emission of NOx is considerably reduced, a long with a decrease in the quantity of soot produced. The experiments were conducted under the conditions of preheated air temperature of 1100°C and a furnace temperature of 1000-1340°C. NOx emission from the 10w-NOx burner is under 50ppm corrected to 11% excess O2. A regenerative burner system with this new type of 10w-NOx burner was applied to a heavy forge furnace. It was confirmed that the low NOx burner meets Japanese environmental regulations . The energy saving was 55%.
