Abstract: Submerged combustion burners having a burner body and a burner tip connected thereto. The burner body has an external conduit and first and second internal conduits substantially concentric therewith, forming first and second 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 of the burner tip. The burner tip has an outer wall and crown connecting the inner and outer walls. The inner and outer walls and crown comprise materials having greater corrosion and/or fatigue resistance than the burner external conduit. The burner tip is connected to the burner body by inner and outer connections, at least one of which includes members interference fit to the burner tip and burner body, the members welded, soldered, or brazed together, in certain instances by fiber laser welding.

Abstract: A bushing system may include a bushing that is configured to receive a molten material. The bushing may include a plate defining a first plurality of apertures through which the molten material flows. The plate may include a longitudinal axis, as well as a first side wall and a second side wall disposed on a side of the plate opposite the first side wall. The first side wall and the second side wall may extend at an upward angle from the plate. The plate may also include a plurality of ribs extending along at least a portion of the plate. The bushing system may also include a tip plate coupleable with the bushing. The tip plate may be configured to receive the molten material from the bushing and may define a second plurality of apertures through which the molten material flows to form fibers.
