    摘要: 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.

    摘要: Methods of processing molten material comprising the step (I) of flowing molten material through an interior of a conduit from a first station to a second station of a glass manufacturing apparatus and the step (II) of cooling the molten material within the interior of the conduit by passing a cooling fluid along an exterior of the conduit. The method further includes the step (III) of directing a travel path of the cooling fluid toward a vertical plane passing through the conduit. In further examples, a glass manufacturing apparatus comprises a first station, a second station, and a conduit configured to provide a travel path for molten material traveling from the first station to the second station. The glass manufacturing apparatus further comprises at least one baffle configured to direct a travel path of cooling fluid toward a vertical plane passing through the conduit.

    摘要: An electrode holder for use in a furnace for melting a batch material to form molten glass is disclosed comprising a refractory coated nose member presented to and in contact with a molten glass material contained within the furnace. The refractory coating is preferably a flame- or plasma-sprayed ceramic such as alumina or zirconia. That protects the nose member from corrosion from the hot molten glass.

    摘要: The present invention provides an apparatus and method for reducing the occurrences of solid defects in float glass due to corrosion of refractory in a glass melting and refining furnace. In making flat glass by the float process, batch materials are fed into a melting and refining furnace and heated to form molten glass. The molten glass passes through the melting section and into a refining section of the furnace where the glass is gradually cooled and conditioned prior to delivering the glass to a forming chamber where the molten glass is floated upon molten metal and formed into a continuous sheet of glass. During the melting operation, alkali vapors from the molten glass accumulate within a downstream portion of the melting section. These vapors attack and corrode those portions of the melting section of the furnace which are constructed from silica refractory. The products of the corrosion are deposited in the molten glass resulting in solid defects. In the present invention, a nonreactive gas is directed into the downstream portion of the melting section at a temperature no greater than that of the molten glass within the melting section and at a gas volume sufficient to reduce the amount of alkali vapors in the downstream portion of the melting section. As a result, the corrosion of the silica refractory is reduced and the total occurrences of solid defects in the glass due to refractory corrosion is reduced. In one embodiment of the invention, the gas is the combustion products from burners that are positioned in the downstream portion of the melting section of the furnace.

    摘要: In the production of high-quality flat glass by the float process, tridymite-frost stone defects are safely avoided by providing burners in the refiner zone of the furnace to shield the crown of that portion of the furnace from contact with alkali vapors, and at the same time providing not only a barrier that substantially separates the refiner-zone headspace from the melter headspace but also preferably a means associated with refiner-zone headspace for exhausting or venting it.
