Publication number: 20120216730Abstract: A method of combining oxygen and fuel in a burner to produce a flame whereby an outer oxidant flow is discharged through an outer oxidant outlet of the burner; a flow of conveyor-gas propelled particulate solid fuel is discharged with a fuel discharge velocity through a fuel outlet of the burner arranged coaxially with respect to the outer oxidant outlet and spaced radially inwardly therefrom; and a first inner oxidant flow is discharged with an inner oxidant discharge velocity, which differs from the fuel discharge velocity, through an inner oxidant end outlet of the burner arranged coaxially with respect to said fuel outlet and spaced radially inwardly therefrom; and whereby a second inner oxidant flow, having a higher oxygen concentration than the conveyor gas is injected into the fuel-conducting passage and mixed with the fuel flow inside said fuel-conducting passage so as to obtain, upstream of the fuel outlet and upstream of the inner oxidant end outlet, an oxygen-enriched conveyor-gas propelled particuType: ApplicationFiled: October 29, 2010Publication date: August 30, 2012Applicant: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Brenice Belasse, Jacques Mulon, Faustine Panier, Xavier Paubel, Remi Tsiava

Publication number: 20110146547Abstract: The present invention provides a combustion furnace that comprises a combustion chamber defining a combustion zone within the combustion chamber and having at least one chamber wall facing the combustion zone, and at least one main particulate fuel burner mounted in a chamber wall and adapted to generate in the combustion zone a main flame directed away from the chamber wall by injecting oxidant in gaseous form and fuel in particulate form into the combustion zone for combustion therein. With regard to the combustion chamber, the main particulate fuel burner has associated therewith at least one auxiliary burner mounted in the burner wall. The auxiliary burner is located in the vicinity of the main particulate fuel burner and is adapted to generate an auxiliary flame in the combustion zone located proximate the chamber wall and at least partially directed towards the main particulate fuel burner.Type: ApplicationFiled: December 23, 2009Publication date: June 23, 2011Applicant: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Niomar M.

Publication number: 20110151386Abstract: The present invention provides a process for operating a combustion furnace, wherein the combustion furnace comprises a combustion chamber defining a combustion zone within the combustion chamber and having at least one chamber wall facing the combustion zone, and at least one particulate fuel burner mounted in a chamber wall and adapted to generate a flame in the combustion zone by injecting oxidant in gaseous form and fuel in particulate form into the combustion zone for combustion therein. In the process, at least one particulate fuel burner is operated so as to alternate between a first phase in which the burner generates a wide flame proximate the chamber wall into which the burner is mounted and a second phase in which the burner generates a narrower flame directed away from the chamber wall into which the burner is mounted.Type: ApplicationFiled: December 23, 2009Publication date: June 23, 2011Applicant: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Niomar M.
