A large-flow precious metal channel is provided, which comprises a molten glass mixed-flow stirring section, at least two molten glass heating, clarifying and cooling sections are connected in parallel at one end of the molten glass mixed-flow stirring section, the other end of which is communicated with a liquid supply tank. The channel is mainly used for the clarification and homogenization of large-flow high-temperature molten glass in the production process of 8.5-generation and higher-generation TFT glass, and provides bubble-free and streak-free high-quality molten glass for subsequent float forming or overflow forming processes.

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.

Described herein are systems and methods for heating and melting glass through the use of induction based heating and methods for forming a fiberglass strand. An exemplary induction melter system for melting glass can include a melting vessel and a heated drain. The melting vessel can include a crucible, a first induction coil positioned around at least a portion of the crucible, and a first electromagnetic current generator coupled to the first induction coil. The heated drain can be coupled to the melting vessel, and the heated drain can include a drain tube, a second induction coil positioned around at least a portion of the drain tube, and a second electromagnetic current generator coupled to the second induction coil.

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.

A glass melting plant refiner for thermal post-treatment of a glass melt containing bubbles, in particular for the production of fiberglass. To reduce the glass melt bubble content produced by submerged combustion burners, a refiner forms a glass melt tank, the glass melt flowing through the tank in a transport direction. The tank has a floor, side walls and a superstructure. A barrier, forming a raised floor part, runs essentially in the transport direction. The barrier forms, at each lateral side, a channel-shaped constriction with the side walls, a width of each constriction transverse to the transport direction being at most 0.45 times the tank width. At least one first fossil fuel heater heats the glass melt from above. At least one second electrical heating device, in each side wall and/or in the floor of the tank in the region of each constriction, extends into the glass melt.
