Abstract
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.
