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: 8469699Abstract: The invention concerns a method for burning a fuel by means of at least one a burner, each burner comprising two half-assemblies (1, 1?) comprising each at least one fuel injecting means (2) associated with a primary oxidant injecting means (3), and at least one secondary oxidant injecting means (4), a first oxidant jet being injected at a first distance from the fuel by the primary injecting means so as to generate a first incomplete combustion, and a second oxidant jet being injected at a second distance (L1), greater than the first distance, from the fuel injecting means so as to generate a second combustion with the remaining fuel of the first incomplete combustion. Said method is characterized in that each half-assembly delivers a combustion power different from the one delivered by the other half-assembly.Type: GrantFiled: December 20, 2005Date of Patent: June 25, 2013Assignee: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Bertrand Leroux, Rémi Tsiava, Patrick Jean-Marie Recourt

Publication number: 20100282185Abstract: The invention relates to a method of combustion of a fuel using an oxygen containing gas and at least one mainly inert gas, in which: the said oxygen containing gas comprises at least 80% of oxygen in volume, the said fuel and the said oxygen containing gas are injected in such a way as to create a flame, the said mainly inert gas is injected in such a way that it is contiguous to and surrounds the flame created by the said fuel and the said oxygen containing gas and that it has a divergent swirl with regard to the flame.Type: ApplicationFiled: January 15, 2009Publication date: November 11, 2010Applicant: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Ivan Sanchez-Molinero, Jacky Laurent, Jacques Mulon, Xavier Paubel, Patrick Jean-Marie Recourt, Remi Pierre Tsiava

Publication number: 20100183989Abstract: A system includes at least one pilot burner and one more powerful main burner. The pilot burner includes at least a first tube open at an end and including at least a first feedline capable of injecting a combustible gas into the first tube. The pilot burner further includes at least a second tube open at an end and including at least a third feedline capable of injecting an oxygen-rich gas into the second tube. The pilot burner further includes at least a second feedline capable of feeding the first tube with air.Type: ApplicationFiled: January 8, 2010Publication date: July 22, 2010Applicant: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Ivan SANCHEZ-MOLINERO, Jacky Laurent, Jacques Mulon, Patrick Jean-Marie Recourt, Rémi Pierre Tsiava

Patent number: 7758336Abstract: The invention relates to processes for the combustion of liquid fuels, including a means of using an oxygenated gas in a combustion zone, applicable to steam boilers, which produces a longer, more uniform and cooler oxygen flame than a conventional oxygen flame. According to the invention, the liquid fuel is injected into the combustion zone in atomized form, the fuel being atomized by bringing a stream of fuel into contact with a stream of atomizing fluid, and: prior to its atomization, the liquid fuel has a viscosity of at least 30×10?6 m2/s, the stream of fuel is brought into contact with the stream of atomizing fluid only in the combustion zone, and oxygenated gas is injected into the combustion zone in stages.Type: GrantFiled: December 14, 2005Date of Patent: July 20, 2010Assignee: L'Air Liquide Societe Anonyme a Directoire et Conseil de Surveillance pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Pascal Tromeur, Remi Tsiava, Bertrand Leroux, Patrick Jean-Marie Recourt

Publication number: 20090280442Abstract: The present invention is a method of combustion of a solid fuel stream with oxygen. The present invention includes introducing a first stream, comprising a first portion of substantially pure oxygen, into a first conduit. The present invention includes introducing a second stream, comprising a solid fuel stream and a conveying media, into a second conduit, wherein the second conduit is concentric with, and surrounding, the first conduit. The present invention includes introducing a third stream, comprising a second portion of substantially pure oxygen, into a third conduit, wherein the third conduit is concentric with, and surrounding, the first conduit and the second conduit. The present invention includes igniting the first stream, the second stream, and the third stream as they exit the first conduit, the second conduit and the third conduit, in such a way as to create a flame.Type: ApplicationFiled: May 5, 2009Publication date: November 12, 2009Applicant: American Air Liquide Inc.Inventors: Rajani Kanth Varagani, Patrick Jean-Marie Recourt, Remi Pierre Tsiava, Xulin Sun, Brenice Belasse
