Abstract: In a regenerative furnace of the type used for melting glass, localized overheating of the regenerating regenerator packing is minimized and heating of the regenerator packing is made more uniform by the utilization of a manifold flue. The gas distribution space is in continuous contact with the regenerator packing while the manifold flue is joined to said gas distribution space at a plurality of points below the regenerative packing. Further, flow control dampers may be located in the flue between the regenerative packing and the joining point of the manifold flue and another damper may be in the manifold flue itself to regulate the passage of gas to and from the regenerative packing so that the packing is evenly heated or cooled.

Abstract: 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.

Abstract: A method of and apparatus for selective control of combustion gas flow in a furnace firing port in a furnace of the type having a plurality of firing ports, each port having a passageway for receiving combustion gas, e.g. preheated air, from a common plenum chamber, wherein the chamber includes a back or target wall in opposed spaced relationship to each of the passageways. A flow control pipe is inserted through a plenum wall directed toward the passageway between the plenum and port. A small quantity of pressurized gas, e.g. air, is injected generally along the flow path of combustion air in the plenum toward passageway to alter the amount of combustion air flowing into the port. In a preferred embodiment, combustion air is increased by injecting air through a target wall flow control pipe cocurrent with the flow to induce additional flow into the port and combustion air is decreased by injecting air countercurrent to the flow adjacent to the passageway to impede flow into the port.

Abstract: A method of controlling NO.sub.x emissions from a glass melting process in which combustion fuel produces exhaust gas in a melting furnace including NO.sub.x compounds is disclosed. Furnace exhaust gas passes from the melting furnace through a regenerator to a zone downstream from the regenerator. Ammonia is injected into the furnace exhaust gas at the downstream zone while the furnace exhaust gas is within a desired temperature range to reduce the amount of NO.sub.x compounds. Additional gas is introduced into the furnace exhaust gas as it moves from the regenerator to the downstream zone whenever the furnace exhaust gas has a temperature which is outside the desired temperature range at the downstream zone so as to modify the furnace exhaust gas temperature such that the furnace exhaust gas is within the desired temperature range when furnace exhaust gas reaches to the downstream zone. In one particular embodiment of the invention, the additional gas is the exhaust from an excess air burner which is injected into the furnace exhaust gas at a temperature such that the furnace exhaust gas and the injected gas have a combined temperature between about 870 to 1090.degree. C. at the downstream zone.

Abstract: The instant invention provides a method of controlling the accumulation of sodium sulfate in the checker packing of a regenerator of a cross-fired regenerative-type glass melting furnace. Typically, glass batch materials are melted within the furnace by combustion of fuel. This combustion produces exhaust gas that is drawn through the regenerator and heats the checker packing. During the melting operation, sodium sulfate gas is formed by the melted glass and is carried with the exhaust gas through the regenerator. The sodium sulfate gas may condense on a portion of the checker packing. As the sodium sulfate condensate accumulates on the checker packing, it may restrict the flow of exhaust gas and/or combustion air through the regenerator. In the instant invention, a section of the regenerator which includes the portion of the checker packing with the condensed sodium sulfate is selectively heated to a temperature sufficient to melt the sodium sulfate, while any additional heating of remaining sections of the regenerator is minimized. In one embodiment of the invention, fuel is injected into a portion of the exhaust gas that passes through the section of the regenerator where the sodium sulfate condensate has accumulated. The fuel burns with the portion of the exhaust gas and heats the portion of the checker packing with the sodium sulfate build-up to melt the sodium sulfate.
