A submerged combustion melting system includes a submerged combustion melter having a housing that defines a melting chamber and one or more vibration damping devices operatively coupled to the housing.

A submerged combustion melting system () includes a submerged combustion melter () having a housing () that defines a melting chamber () and one or more vibration damping devices () operatively coupled to the housing ().

Methods and apparatus for refining and delivering a supply of molten glass include melting a supply of glass in a melter and discharging a stream of molten glass. A refining section is provided to refine the molten glass discharged by the melter and to deliver the molten glass downstream to a glass forming apparatus. The refining section is mounted for movement into and out of contact with the stream of molten glass to connect and disconnect the glass forming apparatus with the stream of molten glass.

Forehearths that create a substantially homogeneous temperature to molten glass forming materials across the end position are provided. A gas cavity, a weir, a refractory block, or a heating element in the forehearth may be utilized to reduce a temperature gradient of molten glass forming materials across the end position. Reducing the temperature difference of the molten glass forming material across the end position permits for improved chemical and physical properties of the glass fibers and the end products formed from the glass fibers. In addition, a reduction in the temperature gradient across the end position produces a more homogenous glass fiber and glass product. Further, a reduction in the shear break rate occurs when the molten glass forming material has a temperature that is substantially the same across the end position, which results in a reduction in the breakage of glass fibers and an increase in manufacturing efficiency.

Apparatuses for controlling the temperature of glass forming materials in forehearths

A plurality of different structural members for reinforcing a plate-like structure, such as a bushing tip plate for intended use in forming fibers from a fluid material supplied to a bushing assembly, are disclosed. Each reinforcing member includes a body having a first portion for attachment to the structure and a second portion having a profile with a variable height including at least one apex. The body may be integrally formed of a single piece of material, or two or formed from more separate pieces of material bonded or secured together. The body may be T-shaped, L-shaped, or F-shaped in cross-section. The second portion of the body may have an inverted V-shaped profile, an inverted W-shaped profile, or an arcuate profile. The at least one apex may be located at the midpoint or elsewhere along the length of the body.

A bushing tip plate support assembly for a bushing in a filament forming apparatus is disclosed. The support assembly improves the flatness of the tip section within the spans between the external support and the center support. The filament forming apparatus includes a bushing having a bottom plate from which nozzles or tips depend. The disclosed support assembly is an improvement on the internal support assemblies in conventional bushings because it has several functions. The support assembly includes two vertical dividers mounted in the bushing. The bottom ends of the dividers are welded to the tops of tip plate gussets in the bushing. The dividers are attached to side plates of the bushing as well. An upper portion of each divider serves as an upper side wall for the bushing and defines part of the throat of the bushing into which the molten glass flows. The dividers also include middle and lower portions with perforations through which the glass in the bushing may flow. The openings permit the dividers to thermally mix and homogenize the glass within the bushing. The dividers provide additional tip plate support to conventional tip plate gussets and resistance to long term creep and sag of the bottom plate, especially at the point of maximum deflection of the tip plate.
