Abstract

PURPOSE:To improve combustion efficiency by a method wherein the flow rate of oxidizing agent, supplied to a plurality of nozzles, is controlled respectively in accordance with the load of combustion and the inclination of a combustion chamber. CONSTITUTION:A controller 12 controls respective flow regulating valves 9 to supply the oxidizing agent of a flow rate in accordance with the load of combustion into a combustion chamber 1 and effect the combustion of molten metal in accordance with the load. When the load is low, for example, the controller 12 controls respective flow regulating valves 9 so that the amount of injection of the oxidizing agent from upper nozzles 4 is reduced and the same from lower nozzles 4 is increased and agitates the molten metal in the combustion chamber 1 actively. When the combustion chamber 1 is slanted and a gyro 11 has detected it, the controller 12 controls respective flow regulating valves 9 based on the detection so that the amount of injection of the oxidizing agent from the nozzles, which are positioned above the free level L of the molten metal, is reduced and the same from the nozzles 4 positioned below the free level L of the molten metal is increased.
