BURNER PANELS INCLUDING DRY-TIP BURNERS, SUBMERGED COMBUSTION MELTERS, AND METHODS

摘要

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.

主权项

1. A 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 set of substantially concentric at least one inner conduit and an outer conduit in the through passage, each conduit comprising proximal and distal ends, 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; 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.
