摘要： According to an aspect of the disclosure, a glass manufacturing system includes a hot-end subsystem, including: a submerged combustion melter that melts feedstock to produce molten glass; a stiller that receives the molten glass from the submerged combustion melter and that includes a stilling tank to still the molten glass and that is configured to control outflow of the stilled molten glass to effectively decouple viscosity of the molten glass from the flow rate of the molten glass and thereby control finer molten glass levels; and a finer that is mechanically decoupled from the stiller, and that receives and fines the stilled molten glass to produce fined molten glass. Many other aspects of the system are also disclosed and claimed.

摘要： A method of producing glass includes receiving unrefined molten glass in a stilling chamber of a stilling tank at a fluctuating flow rate. An intermediate pool of molten glass is held within the stilling chamber of the stilling tank and is heated therein by one or more non-submerged burners. Molten glass flows from the intermediate pool of molten glass to a transfer pool of molten glass held in a spout chamber of a feeding spout that is appended to the stilling tank. A molten glass feed can be drawn from the transfer pool of molten glass and delivered from the feeding spout at a controlled flow rate.

摘要： A method for heating a liquid glass channel of a glass fiber tank furnace. The method comprises: passing oxygen gas and a fuel, via a burner (1), into a channel space (3) for combustion to heat the channel space (3) and a liquid glass (2), wherein the flow rate of the fuel is VF and the flow rate of the oxygen gas is VOX such that the relative velocity difference D=(VF−VOX)VF. The temperature of the channel is 0-1500° C., and the relative velocity difference D is kept to 25% or more. A pure oxygen combustion method is used for heating a tank furnace channel to reduce waste gas emission and heat loss, thereby achieving the goals of energy conservation, reduced carbon emissions, and improve environment friendliness. The fuel flow rate, relative velocity difference, and related parameters can be controlled according to the temperature of the channel, providing excellent uniformity and accurate control of the temperature of the channel.

摘要： A method of forming high strength glass fibers in a refractory-lined glass melter, products made there from and batch compositions suited for use in the method are disclosed. The glass composition for use in the method of the present invention is up to about 64-75 weight percent SiO2, 16-24 weight percent Al2O3, 8-12 weight percent MgO and 0.25-3 weight percent R2O, where R2O equals the sum of Li2O and Na2O, has a fiberizing temperature less than about 2650° F., and a ΔT of at least 80° F. By using oxide-based refractory-lined furnaces the cost of production of glass fibers is substantially reduced in comparison with the cost of fibers produced using a platinum-lined melting furnace. High strength composite articles including the high strength glass fibers are also disclosed.

摘要： A method of forming high strength glass fibers in a glass melter substantially free of platinum or other noble metal materials, products made there from and batch compositions suited for use in the method are disclosed. One glass composition for use in the present invention includes 50-75 weight % SiO2, 13-30 weight % Al2O3, 5-20 weight % MgO, 0-10 weight % CaO, 0 to 5 weight % R2O where R2O is the sum of Li2O, Na2O and K2O, has a higher fiberizing temperature, e.g. 2400-2900° F. (1316-1593° C.) and/or a liquidus temperature that is below the fiberizing temperature by as little as 45° F. (25° C.). Another glass composition for use in the method of the present invention is up to about 64-75 weight percent SiO2, 16-24 weight percent Al2O3, 8-12 weight percent MgO and 0.25-3 weight percent R2O, where R2O equals the sum of Li2O, Na2O and K2O, has a fiberizing temperature less than about 2650° F. (1454° C.), and a ΔT of at least 80° F. (45° C.). A forehearth for transporting molten glass from the glass melter to a forming position is disclosed. By using furnaces and/or forehearths substantially free of platinum or other noble metal materials, the cost of production of glass fibers is significantly reduced in comparison with the cost of fibers produced using a melting furnace lined with noble metal materials. High strength composite articles including the high strength glass fibers are also disclosed.
