A submerged burner for a glass- or rock-melting furnace, including a plurality of in-line injectors, each injector including a cylinder-shaped mixing chamber, with an ejection orifice, a fuel-supply duct and an oxidant-supply duct opening into the mixing chamber at the cylinder jacket in a direction causing a tangential flow of the fuel and of the oxidant relative to the cylinder jacket, and a duct system making it possible for a coolant to flow inside the burner, and, preferably on either side of the alignment of injectors, placed parallel to and all along the latter, solid metal sides rising from the injectors, and protective partitions situated on the top of the solid metal sides.

Submerged burner with multiple injectors

The invention relates to a method of combustion in a furnace provided with a burner comprising an inlet for oxidizer comprising between 10% and 30% of oxygen and an inlet for fuel terminating in the furnace outside the oxidizer inlet and at a distance therefrom of between 0.3 and 4 times the equivalent diameter of the oxidizer inlet, said oxidizer entering the furnace at a speed of between 10 and 60 m/s. This method permits a significant reduction in nitrogen oxide emissions and is suitable for glass furnaces in particular.

Dilute combustion

The invention relates to a process for manufacturing a combustible gas having a lower heating value of at least 1 MJ/Nm, comprising the reaction of an oxidizing gas comprising steam or oxygen or COwith an organic material in contact with a molten silicate bath held in a tank and comprising a heat supply into the molten silicate, said process operating continuously, silicate being regularly drained from the tank and vitrifiable materials being regularly introduced in order to feed the silicate bath. The heat supply is preferably of the submerged combustion type. The invention also relates to a continuous industrial manufacturing process comprising continuous production, in an industrial production unit comprising a gaseous fuel burner that generates combustion gases; continuous production of steam in a boiler; and continuous production of combustible gas in a unit for producing combustible gas comprising the reaction of an oxidizing gas comprising steam with an organic material, the combustion gases being conveyed to the boiler in order to vaporize water and produce steam, the steam produced by the boiler being conveyed to the unit for producing combustible gas in order to react with the organic material, the combustible gas being conveyed to the industrial production unit in order to be burnt therein as a gaseous fuel.
