The process comprises introducing a raw material to be melted in a melting chamber of a furnace, burning fuel through burners so as to generate thermal energy for melting the raw material and to obtain molten glass and a hot stream of fumes having a temperature of 1000-1600[deg] C at an outlet of the melting chamber, introducing the hot stream of fumes from the melting chamber in a preheating installation of the furnace, and heating, in a first thermal exchanger of the preheating installation, a first oxidizing stream using an oxidizing agent having an oxygen content of 21 vol.%.

The tempered stream of oxidant has an oxygen content of 40-90 vol.%. An independent claim is included for an installation for melting glass. |
