Publication number: 20060000239Abstract: The subject of the invention is a process for melting and refining vitrifiable materials, such that all or part of the thermal energy necessary for melting the said vitrifiable materials is supplied by the combustion of fossil fuel(s) with at least one oxidizer gas, the said fuel(s)/gas or the gaseous products resulting from the combustion being injected below the level of the mass of vitrifiable materials (7). The refining of the vitrifiable materials after melting takes place at least partly in the form of a “thin layer”. The invention also relates to the device for implementing the process and to its applications.Type: ApplicationFiled: September 8, 2005Publication date: January 5, 2006Applicant: Saint-Gobain VitrageInventors: Pierre Jeanvoine, Tanguy Massart, Ramon Rodriguez Cuartas, Armando Rodriguez Rodriguez, Juan-Andres Hernandez

Patent number: 6857999Abstract: A subject matter of the invention is a process for destroying waste and/or rendering it inert, in particular industrial, biological or farm-produce waste: use is made of a reactor provided with heating means comprising at least one submerged burner, and said reactor is fed with at least partially vitrifiable materials, which are heated with said heating means in order to form and to maintain, in the reactor, an at least partially liquid/foamy phase at at least 800° C. Then said waste is introduced into said phase in order for its organic components to be decomposed therein by combustion and/or its inorganic components to be melted or coated in said phase. Finally, said phase, charged with molten/coated waste and/or with combustion products from said waste, is withdrawn from the reactor.Type: GrantFiled: December 12, 2001Date of Patent: February 22, 2005Assignee: Saint-Gobain Glass FranceInventor: Pierre Jeanvoine
