Abstract
The invention concerns a combustion method for industrial furnace comprising an arrangement of two substantially parallel and symmetrical burner assemblies (G, D). Each burner assembly comprises a fuel injector (<SUB>G</SUB>,<SUB>D</SUB>) and three oxidant injectors (<SUB>G</SUB>,<SUB>G</SUB>,<SUB>G</SUB>,<SUB>D</SUB>,<SUB>D</SUB>,<SUB>D</SUB>) arranged at increasing distances from the fuel injector. An oxidant supply system cyclically distributes a specific flow of oxidant among some at least of the second and third injectors of the burner assemblies (<SUB>G</SUB>,<SUB>G</SUB>,<SUB>D</SUB>,<SUB>D</SUB>). The amount of nitrogen monoxide produced upon combustion is thus reduced, while ensuring a good distribution of the heating power in the furnace.
