摘要: In a process for manufacturing glass, a mixture of solid glass-forming materials (18) may be melted by application of heat from one or more submerged combustion burners (34) to produce a volume of unrefined molten glass comprising, by volume, 20% to 40% gas bubbles. A refining agent may be introduced into the unrefined molten glass to promote gas bubble removal from the molten glass. The unrefined molten glass including the refining agent may be heated at a temperature in the range of 1200° C. to 1500° C. to produce a volume of refined molten glass. The refined molten glass may comprise, by volume, fewer gas bubbles than the unrefined molten glass. A colorant material may be introduced into the refined molten glass to produce a volume of molten glass having a final desired color.

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 batch feeding apparatus, a submerged combustion melter, and method are disclosed. The batch feeding apparatus can include a batch feeding apparatus comprising a detachable feeder alcove for providing batch material to a melter, the feeder alcove including at least one side wall and a cover; and a batch feeder sealingly coupled to the cover, that feeds the batch material to the feeder alcove. The batch feeding apparatus may include an extendable panel that extends downwardly below a batch inlet of the feeder alcove to molten glass, and is configured to maintain contact with the molten glass to seal off a feeder alcove interior. Additionally, the batch feeding apparatus may include a heating device, a cleaning device, and/or a storage device.

摘要: A method of producing glass includes drawing unrefined foamy molten glass from a glass melt held in a submerged combustion melter and introducing the unrefined foamy molten glass into a stilling chamber of a stilling tank. 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 rate.

摘要: A glass includes a first glass portion and a second glass portion. The first glass portion has a higher ion packing density than the second glass portion (has a composition that forms a glass in which, out of plastic deformation characteristics, plastic flow is dominant). The second glass has a lower ion packing density than the first glass portion (has a composition that forms a glass in which, out of the plastic deformation characteristics, densification is dominant).

摘要: A method of producing and fining glass includes monitoring a temperature of a molten glass bath contained within a fining chamber of a fining vessel and, based on the monitored temperature, controlling an amount of a sulfate chemical fining agent added into a glass melt contained within an interior reaction chamber of an upstream submerged combustion melter that feeds the fining vessel. The temperature of the molten glass bath may be determined within a temperature indication zone that encompasses a subsurface portion of the molten glass bath that lies adjacent to a floor of a housing of the fining vessel. By monitoring the temperature of the molten glass bath and controlling the amount of the sulfate chemical fining agent added to the glass melt of the submerged combustion melter, the wasteful use of the sulfate chemical fining agent can be minimized and the fining process rendered more efficient.

摘要: A method of of fining low-density submerged combustion glass includes introducing unfined molten glass produced in a submerged combustion melter into a fining chamber of a fining tank and, further, introducing additive particles into the fining chamber that comprise a glass reactant material and one or more fining agents. The one or more fining agents are released into the molten glass bath upon consumption of the additive particles in the molten glass bath to chemically fine the molten glass bath and the glass reactant material includes one or more materials that integrate into the molten glass bath upon melting. Additionally, the method includes discharging fined molten glass out of the fining chamber of the fining tank. The discharged fined molten glass has a volume percentage of gas bubbles that is less than the volume percentage of gas bubbles in the unfined molten glass introduced into the fining chamber.

摘要: A method of fining low-density submerged combustion glass is disclosed. The method involves introducing unfined molten glass produced in a submerged combustion melter into a fining chamber of a downstream fining tank. Additionally, additive particles are also introduced into the fining chamber to release one or more fining agents into the molten glass bath contained in the fining chamber to accelerate the removal of bubbles from the molten glass bath. The fining of the molten glass bath as assisted by the one or more fining agents allows for fined glass to be discharged from the fining tank that has fewer bubbles and a greater density than that of the unfined molten glass introduced into the fining tank. Additive particles that include a physical mixture of a glass reactant material and the fining agent(s) are also disclosed.

摘要: A melting furnace feedstock charger includes a charger conduit including an inlet to receive feedstock and an outlet at an outlet portion of the charger conduit to transmit feedstock, and an auger or other feedstock mover coupled to the charger conduit to convey feedstock in a direction from the inlet toward the outlet. A gate may be detachably coupled to the outlet portion of the charger conduit and configured to be coupled directly to a wall of a melting vessel. The auger may have a helical flight with an outer diameter of varying size. A stripper may be movably carried by the charger conduit and may include a stripping tool moved by an actuator with respect to the charger conduit to facilitate transmission of feedstock and/or to strip away clogged feedstock and/or molten material.
