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: 8714969Abstract: The invention relates to a fuel combustion method in which one jet of fuel and at least two jets of oxidant are injected. According to the invention, the first jet of oxidant, known as the primary oxidant 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 oxidant is injected at a distance from the jet of fuel such as to combust with the part of the fuel present in the gases produced by the first combustion. Moreover, the primary oxidant jet is divided into two primary jets, namely: a first primary oxidant jet, known as the central jet, which is injected at the centre of the jet of fuel; and a second primary oxidant jet, knows as the sheathing jet, which is injected coaxially around the fuel jet.Type: GrantFiled: December 6, 2004Date of Patent: May 6, 2014Assignee: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Bertrand Leroux, Remi Pierre Tsiava

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
