Abstract:
Submerged combustion burners having a burner body (6) and a burner tip (4) connected thereto. The burner body (6) has an external conduit (10) and first (12) and second (14) internal conduits substantially concentric therewith, forming first (11) and second (13) annuli for passing a cooling fluid therethrough. The burner includes a generally central flow passage for a combustible mixture, the flow passage partially defined by an inner wall (28) of the burner tip (4). The burner tip (4) has an outer wall (30) and crown (32) connecting the inner (28) and outer walls (30). The inner (28) and outer (30) walls and crown (32) comprise materials having greater corrosion and/or fatigue resistance than the burner external conduit. The burner tip (4) is connected to the burner body by inner and outer connections, at least one of which includes members interference fit to the burner tip (4) and burner body (6), the members welded, soldered, or brazed together, in certain instances by fiber laser welding.
Abstract:
Melters for glass forming apparatuses and glass forming apparatuses comprising the same are disclosed. According to one embodiment, a melter for melting glass batch materials includes a base portion and a rigid exoskeleton rigidly attached to the base portion and comprising a plurality of upright members interconnected with a plurality of cross members defining an exoskeleton interior volume. Connection nodes formed at intersections of the plurality of cross members with upper ends of the plurality of upright members are constrained from movement relative to the base portion in a longitudinal direction, a transverse direction, and a vertical direction. A tank assembly is positioned on the base portion in the exoskeleton interior volume and coupled to the rigid exoskeleton. In some embodiments, the melter has a dynamic resistance greater than 0.3.
Abstract:
A melter apparatus includes a floor, a ceiling, and a wall connecting the floor and ceiling at a perimeter of the floor and ceiling, a melting zone being defined by the floor, ceiling and wall, the melting zone having a feed inlet and a molten glass outlet positioned at opposing ends of the melting zone. Melter apparatus include an exit end having a melter exit structure for discharging turbulent molten glass formed by one or more submerged combustion burners, the melter exit structure fluidly and mechanically connecting the melter vessel to a molten glass conditioning channel. The melter exit structure includes a fluid-cooled transition channel configured to form a frozen glass layer or highly viscous glass layer, or combination thereof, on inner surfaces of the fluid-cooled transition channel and thus protect the melter exit structure from mechanical energy imparted from the melter vessel to the melter exit structure.
Abstract:

Abstract:
A substantially-isolated/controlled, limited-volume, gas-filled space (e.g., 113b) is formed over at least one free (open) surface of flowing molten glass in a manufacturing line used to produce glass sheets (137), e.g., a manufacturing line employing the fusion process to produce glass sheets suitable for use as substrates for liquid crystal displays. At least a portion of the space comprises a platinum-group metal, e.g., a platinum-rhodium alloy, which can serve as a source of platinum-group condensate defects. The use of the substantially-isolated/controlled, limited-volume, gas filled space substantially reduces the level of such platinum-group condensate defects in the glass sheets, e.g., by more than 50%.
