    Abstract: Disclosed is a burner for oxidant gasification of pulverized fuels under high pressures of e.g. 80 bar (8 MPa) and temperatures of e.g. 1200 to 1900° C. in reactors with liquid slag removal for oxygen gasification, the individual pulverized fuel supply tubes in the burner are designed such that, while retaining the entry cross-sectional area of the tube, the cross-section makes a systematic transition to a curved rectangular duct matched to the annulus. This means that fuel feeding ends immediately adjacent to the oxidant duct, and the flow rate provided in the feeding element is maintained up to the outlet, thereby ensuring trouble-free flow of the pulverized fuel and reducing the amount of inert gas required for purging the feeding element in the non-operational state.

    Abstract: A burner has a body portion and a main outlet. Fuel and primary oxidant outlets are arranged upstream of the main outlet and are disposed substantially concentrically about the axis of the burner. A chamber inside the body portion provides a place for the mixing of the fuel and oxidant. A laval nozzle provides acceleration of the mixed fuel and oxidant. Particulate matter are injected into a secondary oxidant flow immediately adjacent and downstream of the accelerating nozzle. The burner can be used in an electric arc furnace for decarburization of metals as well as post combustion. The burner can be mounted in a water-cooled box and can be fitted with an oxygen port for extra oxygen for post combustion while the burner injects hot oxygen and carbon for slag forming.

    Abstract: The technical field of the invention is making a burner capable of using one or more fuels, optionally simultaneously, together with particular features for the gas feed ducts. Such a burner comprises at least four substantially concentric ducts for feeding fuel and primary combustion air, including a duct for axial air and a duct for rotary air disposed outside any fuel outlet opening, and a central stabilizer placed at the outlet of a central primary air delivery duct opening out through orifices of said stabilizer, which stabilizer projects radially relative to any opening of a tube placed inside said central primary air duct and inside which a fuel pipe opens out. According to the invention, said burner has at least one additional gas feed opening out into said stabilizer and disposed around said opening having any diameter lying between the tube within which the fuel pipe opens out and the outer tube defining the central primary air delivery duct.
