ABSTRACT:
A method an apparatus for combustion with a minimum of NOx emission in various industrial furnaces and boilers. By injecting air for combustion into a furnace through the burner tile or air baffle in the deviated flow pattern asymmetrical with respect to the burner tile or baffle axis, the quick mixing of the air and fuel in early stages of combustion is suppressed to provide for a relatively gentle combustion and allow the burnt gas self-circulation to take place effectively, thereby minimizing the emission of nitrogen oxides.
