Publication number: 20220010472Abstract: The invention relates to a method and facility for manufacturing a cross-linked fiberglass material, in which melted glass is produced in a melting furnace heated via combustion of a fuel with an oxygen-rich oxidant. The melted glass is converted into glass filaments, the filaments are bonded, a sheet is made from the bonded filaments, and the sheet is then cross-linked. The fumes from the melting furnace are used to preheat a combustion reagent in two steps: a first step in which air is heated via heat exchange with the fumes, and a second step in which the combustion reagent is preheated via heat exchange with the hot air. The air is then used in the cross-linking step of the method for converting the melted glass into a fiberglass material.Type: ApplicationFiled: September 23, 2021Publication date: January 13, 2022Applicant: L'Air Liquide, Societe Anonyme pour l'Etude et l?Exploitation des Procedes Georges ClaudeInventors: Luc JARRY, Youssef JOUMANI, Gregoire BEASSE

Patent number: 9862632Abstract: The invention relates to a unit and method for melting in a furnace comprising a combustion-heated melting chamber, in which the air is heated by means of heat exchange with the fumes generated by combustion. The heated air is used in a gas turbine in order to generate electrical and/or mechanical energy. In addition, the effluent from the gas turbine is used to pre-heat the combustion oxygen and/or gaseous fuel upstream of the melting chamber.Type: GrantFiled: December 5, 2013Date of Patent: January 9, 2018Assignee: L'Air Liquide Société Anonyme Pour L'Étude Et L'Exploitation Des Procedes Georges ClaudeInventors: Benoit Davidian, Youssef Joumani, Jocelyn Le Dirach, Jean-Pierre Tranier

Patent number: 9851102Abstract: A plurality of independently flow rate-controlled flows of oxidant may be preheated at a heat exchanger (or both oxidant and fuel at separate heat exchangers) by heat exchange with a hot shell-side (heat transfer) fluid. The separate flows of hot oxidant are directed to associated separate burners where they combust with flows of fuel to produce hot combustion gases. The hot combustion gases are used to preheat the hot shell-side fluid at a recuperator or regenerator.Type: GrantFiled: July 31, 2013Date of Patent: December 26, 2017Assignee: L'Air Liquide Société Anonyme Pour L'Étude Et L'Exploitation Des Procedes Georges ClaudeInventors: Taekyu Kang, James J.
