Burner panels including dry-tip burners, submerged combustion melters, and methods
First Claim
1. A submerged combustion burner panel comprising:
- (a) a panel body having a first major surface defined by a lower fluid-cooled portion of the panel body, and a second major surface defined by an upper non-fluid cooled portion of the panel body, the lower fluid-cooled portion and the upper non-fluid cooled portion positioned in layers, the panel body having at least one through passage extending from the first to the second major surface, the panel body supporting at least one non-fluid cooled set of substantially concentric inner conduit and an outer conduit in the through passage, each conduit comprising proximal and distal ends, the inner conduit forming a primary passage and the outer conduit forming a secondary passage between the outer conduit and the inner conduit, the distal end of each of the inner conduit extending beyond the distal end of the outer conduit a distance H; and
(b) a non-fluid cooled shaped annular disk protective member associated with each set, each non-fluid cooled shaped annular disk protective member having a through passage and a thickness equal to the distance H, and supported at least partially internally of the panel body and positioned at the distal end of the outer conduit of each set, the lower fluid-cooled portion of the panel body supporting both an upper portion of the outer conduit of the sets of conduits and the associated protective members in the through passage.

Abstract
Combustion burner panels, submerged combustion melters including one or more of the panels, and methods of using the same are disclosed. In certain embodiments, the burner panel includes a panel body having a first major surface defined by a lower fluid-cooled portion of the panel body, and a second major surface defined by an upper non-fluid cooled portion of the panel body. The panel body has at least one through passage extending from the first to the second major surface, the through passages accommodating a set of substantially concentric inner and outer conduits. The inner conduit forms a primary passage for fuel or oxidant, and the outer conduit forms a secondary passage between the outer conduit and the inner conduit for fuel or oxidant. A protective member is associated with each set. The burner panels promote burner life and melter campaign length.

15. A submerged combustion burner panel comprising:
-
(a) a panel body having a first major surface defined by a lower fluid-cooled portion of the panel body, and a second major surface defined by an upper non-fluid cooled portion of the panel body, the panel body having at least one through passage extending from the first to the second major surface, the panel body supporting at least one non-fluid cooled set of substantially concentric inner conduit and an outer conduit in the through passage, each conduit comprising proximal and distal ends, the inner conduit forming a primary passage and the outer conduit forming a secondary passage between the outer conduit and the inner conduit, the distal end of the inner conduit recessed from the distal end of the outer conduit a distance H; and (b) a non-fluid cooled protective member associated with each set, each non-fluid cooled protective member supported at least partially internally of the panel body and positioned at the distal end of the outer conduit of each set, the non-fluid cooled protective member is a shaped annular disk having a through passage and a thickness equal to the distance H, the through passage of the shaped annular disk having an internal diameter d1 substantially equal to but not larger than an internal diameter D1 of the outer conduit, the shaped annular disk having a top surface and a bottom surface that are parallel, and each of the top and bottom surfaces are perpendicular to a longitudinal axis of the inner conduit, the lower fluid-cooled portion of the panel body supporting both an upper portion of the outer conduit of the sets of conduits and the associated protective members in the through passage. - View Dependent Claims (16, 17, 18, 19, 20, 21)
