Abstract
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.
