Abstract
A process for melting and refining vitrifiable materials. In this method all or part of the thermal energy necessary for melting the vitrifiable materials is supplied by the combustion of fossil fuel with at least one oxidizer gas, the fuel, gas or the gaseous products resulting from their combustion are injected below the level of the mass of the vitrifiable materials. The refining of the vitrifiable materials after melting includes at least the step of subjecting them to subatmospheric pressure.
