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 feed assembly having a hollow tubular body and a batch charger disposed within the hollow tubular body is disclosed. The hollow tubular body extends along a central axis from a first end to a second end and, further, comprises a port that tapers from a first port end to a second port end at the second end of the tubular body. The batch charger includes a first charger end proximate the first end of the tubular body and a second charger end proximate the second end of the tubular body. The second charger end is spaced away from the second end of the tubular body to provide a port space within the port. An apparatus that includes a melting chamber and a feed assembly is also disclosed along with a method of feeding batch materials into a melting chamber.

摘要： A submerged combustion melter and system are disclosed. The submerged combustion melter includes a bottom wall, at least one side wall extending upwardly from the bottom wall, a crown extending inwardly with respect to the at least one side wall and over the bottom wall to establish a melting chamber, an exhaust port configured to exhaust gas from the melting chamber, at least one baffle extending from the at least one side wall to divide the melting chamber into melting sub-chambers that share the exhaust port, at least one inlet configured for introducing a glass batch into the submerged combustion melter, and at least one outlet configured to remove molten glass from the at least one melting chamber.

摘要： An assembly for forming a parison within a mold of a glass forming machine includes a plunger cylinder having a first end configured to be received by the mold and form the parison and a second end. The cylinder is configured for movement along a translational axis. An alignment plate defines a bore through which the cylinder extends. The alignment plate is configured to be affixed to a fixed member of the forming machine after movement of the alignment plate in a plane perpendicular to the translational axis to align the translational axis of the cylinder with a centerline of the mold. A height adjustment plate is spaced from, and hung from, the alignment plate and configured to support the second end of the cylinder. The height adjustment plate is movable relative to the alignment plate to cause a corresponding movement of the cylinder along the translational axis.

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. The unrefined molten glass merges with an intermediate pool of molten glass being held within the stilling chamber. The intermediate pool of molten glass is heated in the stilling chamber 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. Additionally, a molten glass feed is delivered out of the feeding spout from the transfer pool of molten glass at a controlled flow rate.

摘要： A submerged combustion melter includes first, second, third, and fourth side walls extending upwardly from a bottom wall, a crown extending inwardly with respect to the side walls and over the bottom wall to establish a melting chamber, an exhaust port configured to exhaust gas from the melting chamber, a baffle coupled to and extending inwardly from the third side wall to divide the melting chamber into melting sub-chambers that share the exhaust port and having an end spaced away from the fourth side wall, an inlet configured for introducing a glass batch into the melter, and an outlet configured to remove molten glass from the melting sub-chambers, which direct product flow in a laterally undulating flow path from the inlet to the outlet.

摘要： A submerged combustion melting system includes a furnace including a tank with a floor, a roof, a perimeter wall, and an interior, and burners to melt glass feedstock into molten glass, a batch inlet, a molten glass outlet, and an exhaust outlet. An exhaust system is in fluid communication with the interior of the tank, and includes a flue in fluid communication with the exhaust outlet. A refractory-lined hood may be in fluid communication with the flue, which may be fluid-cooled including fluid-cooled perimeter panels and lower and upper baffles. The hood may include a protrusion that protrudes into a downstream horizontal exhaust path and has an excurvate upper surface to streamline flow of exhaust gas through the hood to prevent gas recirculation and formation of condensate piles in the hood.
