065347000 | MELTING POT OR FURNACE WITH STRUCTURALLY DEFINED DELIVERY OR FINING ZONE | 6 |
20120180531 | GLASS FURNACE, IN PARTICULAR FOR CLEAR OR ULTRA-CLEAR GLASS, WITH A REDUCTION IN THE PRIMARY RECIRCULATION - The invention relates to a glass furnace for heating and melting materials to be vitrified, in which two loops (B | 07-19-2012 |
20120216578 | GLASS FURNACE HAVING CONTROLLED SECONDARY RECIRCULATION OF THE GLASS - The invention relates to a furnace for melting and fining glass, which includes: a vault provided with a heating means, a hearth ( | 08-30-2012 |
20140075997 | SILICON PURIFICATION METHOD AND SILICON PURIFICATION DEVICE - The silicon purification method uses a silicon purification device including at least a crucible for loading a silicon metal and a plasma torch, and purifies the silicon metal by injecting a plasma gas from the plasma torch toward a melt surface of the silicon metal loaded in the crucible in a state where an angle formed by the melt surface and the plasma gas is set in the range of 20° to 80°. | 03-20-2014 |
20140190214 | SUBMERGED COMBUSTION GLASS MANUFACTURING SYSTEM AND METHOD - Submerged combustion glass manufacturing systems include a melter having a floor, a roof, a wall structure connecting the floor and roof, and an exhaust passage through the roof. One or more submerged combustion burners are mounted in the floor and/or wall structure discharging combustion products under a level of material being melted in the melter and create turbulent conditions in the material. The melter exhausts through an exhaust structure connecting the exhaust passage with an exhaust stack. The exhaust structure includes a barrier defining an exhaust chamber having an interior surface, the exhaust chamber having a cross-sectional area greater than that of the exhaust stack but less than the melter. The barrier maintains temperature and pressure in the exhaust structure at values sufficient to substantially prevent condensation of exhaust material on the interior surface. | 07-10-2014 |
20140196503 | WATER COOLED OXYGEN LANCE FOR USE IN A FLOAT GLASS FURNACE AND/OR FLOAT GLASS FURNACE USING THE SAME - A float glass furnace includes a melting furnace which heats raw materials to form a molten glass batch, a working end where the molten glass batch is cooled, at least one regenerator which introduces heated combustion air into the melting furnace through a port neck, and at least one oxygen lance in or proximate the port neck. The oxygen lance includes a lance pipe in fluid communication with the port neck, an outer shell surrounding the lance pipe, an inlet water passageway in fluid communication with a channel(s) between an exterior surface of the lance pipe and an interior surface of the outer shell, and an outlet water passageway in fluid communication with the channel(s). | 07-17-2014 |
20150329400 | BURNER APPARATUS, SUBMERGED COMBUSTION MELTERS INCLUDING THE BURNER, AND METHODS OF USE - Apparatus includes a first and second conduits configured to form an annulus between them. An adjustable structure includes a body having an upper surface, a lower surface, and a circumferential surface abutting a portion of the internal surface of the second conduit. The structure is adjustable axially in relation to and removably attached to the first conduit via a hub. The hub defines a central passage for fuel or oxidant. The body has one or more non-central through passages configured such that flow of an oxidant or fuel therethrough causes the fuel or oxidant to intersect flow of fuel or oxidant exiting from the central passage in a region above the upper surface of the body. | 11-19-2015 |
