Consumable tip burners, submerged combustion melters including same, and methods
First Claim
1. A combustion burner for submerged combustion comprising:
- (a) an annular liquid cooled jacket defining a central longitudinal through passage;
(b) at least one inner conduit and a substantially concentric outer conduit positioned in the through passage, each conduit comprising proximal and distal ends, all conduit distal ends extending beyond a distal end of the annular liquid cooled jacket, the conduits configured so that the outer and inner conduits are movable axially, the at least one inner conduit forming a primary passage and the outer conduit forming a secondary passage between the outer conduit and the at least one inner conduit, the at least one inner conduit and the outer conduit having positions selected from the group consisting of;
(i) the distal end of the outer conduit extends beyond the distal end of the at least one inner conduit, and(ii) the distal end of the at least one inner conduit extends beyond the distal end of the outer conduit; and
(c) the outer conduit having an exterior surface configured along a lower portion thereof with at least two sets of axially spaced dog teeth, one set mating with adjacent dog teeth on one or more dog connectors secured in the annular liquid cooled jacket, the one or more dogs connectors configured to be operable hydraulically between a locked position and a release position, allowing the outer conduit to be repositioned axially relative to the annular liquid cooled jacket.

Abstract
Combustion burners, burner panels, submerged combustion melters including the panels, and methods of using the same are disclosed. In certain embodiments, the burner includes an annular liquid cooled jacket defining a central longitudinal through passage. An inner conduit is positioned substantially concentrically within an outer conduit, the latter positioned in the through passage, each conduit comprising proximal and distal ends, the conduits configured so that the outer and inner conduits are movable axially. The inner conduit forms a primary passage and the outer conduit forms a secondary passage between the outer conduit and the inner conduit. In one embodiment the outer conduit has an exterior surface configured along at least a portion thereof with threads mating with adjacent threads on an inner surface of the annular liquid cooled jacket. Other embodiments including lock and release dogs or bolt arrangements. The burners promote burner life and melter campaign length.
