Patent number: 9285113Abstract: A burner has a fuel/oxidant nozzles and a pair of dynamical lances spaced on either side thereof that inject a jet of fuel and primary oxidant along a fuel injection axis, and jets of secondary oxidant, respectively. Jets of actuating fluid impinge against the jets of secondary oxidant to fluidically angle the jets of secondary oxidant away from the fuel injection axis.

Patent number: 8827691Abstract: During a heating phase, injection of a jet of fuel and oxidant (fuel annularly enshrouding oxidant or oxidant annularly enshrouding fuel) from a fuel-oxidant nozzle is combusted in a combustion space. During a transition from the heating phase to a distributed combustion phase, an amount of a secondary portion of either the fuel or oxidant is injected as a jet into the combustion space while the primary portion of that same reactant from the fuel-oxidant nozzle is decreased. At some point during the transition phase, a jet of actuating fluid is injected at an angle towards the jet of reactants from the fuel-oxidant nozzle and/or towards the jet of the secondary portion of reactant. The jet of primary portions of reactants and/or secondary portion of reactant is caused to be bent/deviated towards the other of the two jets. The staging of the secondary portion of reactant is increased until a desired degrees of staging and commencement of a distributed combustion phase are achieved.Type: GrantFiled: July 31, 2010Date of Patent: September 9, 2014Assignees: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges Claude, American Air Liquide, Inc.Inventors: Rajeev S.

Patent number: 8696349Abstract: The invention relates to a method for the combustion of a fuel using an oxygenated gas, in which a jet of fuel and at least two jets of oxygen-rich oxygenated gas are injected. According to the invention, the first jet of oxygen-rich oxygenated gas, known as the primary jet, is injected such as to be in contact with the jet of fuel and to produce a first incomplete combustion, the gases produced by said first combustion comprising at least one part of the fuel, and the second jet of oxygen-rich oxygenated gas is injected at a distance I1 from the jet of fuel such as to combust with a first part of the fuel present in the gases produced by the first combustion. Moreover, a low-oxygen oxygenated gas is injected at a distance I2 from the jet of fuel such as to combust with a second part of the fuel present in the gases produced by the first combustion, I2 being greater than I1.Type: GrantFiled: December 3, 2004Date of Patent: April 15, 2014Assignee: L'Air Liquide, Société Anonyme pour l'Étude et l'Éxploitation des Procédés Georges ClaudeInventors: Bertrand Leroux, Remi Pierre Tsiava, Patrick Jean-Marie Recourt, Benoit Grand, Pascal Duperray, Loic Sylvestre, Mohand Amirat

Patent number: 8336335Abstract: The invention relates to a method for melting vitrifiable materials in a low-capacity oven, wherein at least part of the melting energy is supplied by two oxy-burners projecting into the melting chamber through the upstream wall and arranged on opposite sides of a vertical plane in which a longitudinal axis of the melting chamber is situated, in such a way as to create two flames, the respective injection axes thereof crossing at a distance from the upstream wall, between ? and ¾ of the length L of the melting chamber.Type: GrantFiled: July 10, 2008Date of Patent: December 25, 2012Assignee: L'Air Liquide Societe Anonyme Pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Philippe Beaudoin, Gabriel Constantin, Pascal Duperray, Son Ha Giang, Benoit Grand, Luc Jarry, Robert Kalcevic, Bertrand Leroux, Alban Poirier, Rémi Tsiava

Patent number: 8231380Abstract: 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 (10<SUB>G</SUB>, 10<SUB>D</SUB>) and three oxidant injectors (1<SUB>G</SUB>, 2<SUB>G</SUB>, 3<SUB>G</SUB>, 1<SUB>D</SUB>, 2<SUB>D</SUB>, 3<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 (2<SUB>G</SUB>, 3<SUB>G</SUB>, 2<SUB>D</SUB>, 3<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.Type: GrantFiled: December 5, 2005Date of Patent: July 31, 2012Assignee: L'Air Liquide Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Rémi Tsiava, Benoit Grand, Patrick Recourt, Bertrand Leroux
