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.

The invention relates to a method and facility for manufacturing a fiberglass material, in which melted glass is produced in a melting furnace heated via combustion of a fuel with an oxygen-rich oxidant. The fumes generated 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 method for converting the melted glass into a fiberglass material.

Method and facility for manufacturing a fiberglass material

The invention relates to a fiberglass material manufacture method and facility, were in molten glass is converted into fiberglass material via the steps of spinning, drawing, sizing, and collecting, followed by a step of producing a resulting fiberglass material that is then subjected to thermal desizing. The fumes from the melting furnace are used to preheat a combustion reagent from the melting furnace 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 then being used in the step of desizing the fiberglass material.

Fiberglass material manufacture method comprising steps of sizing and desizing, and facility suitable for implementing said method

Combustion method and installation in which an oxygen-rich oxidant is preheated by exchange of heat with a heat-transfer fluid, upstream of the combustion chamber, in which method and installation an auxiliary gas is heated by heat exchange with a first proportion of the hot flue gases discharged from the chamber, and in which method and installation the heat-transfer fluid comprises a mixture of at least a proportion of the heated auxiliary gas with a proportion of hot flue gases.

Combustion method and installation with optimized energy recuperation

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.

Energy recovery from fumes from a melting furnace using a gas turbine and heat exchangers

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.

The invention relates to a melting unit and method in which: a melting chamber is heated by means of combustion, the combustion fumes are used to heat the air used as a heat-transfer gas, the heated air is used to pre-heat the combustion oxygen and/or the gaseous fuel, the tempered air resulting from the pre-heating is compressed, the compressed tempered air is heated by means of heat exchange with the combustion fumes, and the mechanical and/or electrical energy is generated by expansion of the heated compressed air.

An ion transport membrane, a heat exchanger, and a recuperator are integrated with a float glass manufacturing process. Only feeds of fuel and air are necessary for producing hot oxygen for a melting furnace and a nitrogen-enriched stream to a float bath. The oxygen and nitrogen are produced on-site without requiring cryogenic distillation.

Ion transport membranes in float glass manufacturing

Ion transport membranes are integrated with a glass melting furnace and a float glass bath. Only feeds of air, steam and hydrocarbon are necessary for producing hot oxygen for the melting furnace and a mixture of nitrogen, carbon dioxide, and hydrogen for the float glass bath.

Process and apparatus for melting raw material in an electric arc furnace using a flame of variable direction, the apparatus comprising a burner and a lance whereby the lance outlet opening and the burner outlet opening are not concentric and are located at a distance from one another, and whereby the lance axis forms an angle with the burner axis in the range from 10&#xb0; to 40.
