Patent number: 8003845Abstract: The invention concerns a process enabling the complete combustion and oxidation of the mineral fraction of combustible waste contained in an apparatus intended to treat waste by direct incineration-vitrification, said process comprising the following steps: a step to add said waste to the apparatus for its depositing on the surface of a molten glass bath contained in the apparatus, an incineration and oxidation step of the waste on the surface of the glass bath, an incorporation step to incorporate combustion products in the glass during which the glass bath, the combustion products and any vitrification additives added to the glass bath are heated until a paste-like, liquid mass is obtained, a step during which said mass is removed from the apparatus and left to cool to obtain finally what is called a confinement matrix, said process being characterized in that the complete combustion and oxidation of the waste is achieved partly during the waste adding step and partly during the waste incineration and oxType: GrantFiled: May 25, 2005Date of Patent: August 23, 2011Assignees: Commissariat a l'Energie Atomique, Compagnie Generale des Matieres NucleairesInventors: Olivier Pinet, Christophe Girold

Patent number: 7730745Abstract: Process for combustion and vitrification of waste in which at least one oxygen plasma jet is associated with a continuous melting device by high frequency direct induction. The crucible is composed of a continuous external shell and a sole plate, both cooled by a liquid circulating in internal channels. The inductor is placed below the sole plate. There is a gravity drain valve at the bottom or on the side.Type: GrantFiled: September 4, 2008Date of Patent: June 8, 2010Assignees: Commissariat a l'Energie Atomique, Compagnie Generale des Matieres NucleairesInventors: Christophe Girold, Lionel Bruguiere, Roger Boen, Armand Bonnetier, Louis Bojat
