Abstract

A method of reducing the NOx emission during the combustion of nitrogenous fuels in burners in closed combustion chambers, in which the combustion air is divided into two streams, the first stream 2 being supplied directly to the burner to effect partial combustion of the fuel in a primary zone 6, and the second stream 4 being supplied separately from the burner to its flame in a secondary zone 7 to effect complete combustion of the fuel. The air in the first stream is insufficient to effect complete combustion of the fuel, and the air in the second stream is in excess of that required for complete combustion. <IMAGE>
