  • Patent number: 4473348
    Abstract: The burner for metallurgical furnaces comprises a main combustion chamber (7) and an auxiliary combustion chamber (5) presenting a plurality of outlet channels (6) communicating with the main combustion chamber (7). To the main combustion chamber there is fed in a pulsating manner a primary mix of fuel gas and air in stoichiometric ratio, and, during the intervals between the feed pulses, a secondary mix of fuel gas and air with a coefficient of excess air of 1.15 to 1.35 and at a rate of flow corresponding to 1 to 3% of the nominal rate of flow. To the auxiliary combustion chamber (5) there is instead continuously fed an auxiliary mix of fuel gas and air with a coefficient of excess air of 0.65 to 0.85 and at a rate of flow corresponding to 1 to 3% of the rate of flow of the primary mix. The combustion products of the auxiliary mix stay in the auxiliary combustion chamber (5) for a very short time, more particularly for about from 0.005 to 0.01 sec.
