Submerged conbustion melters, wall structures or panels of same, and methods of using same

Submerged combustion burner panels, submerged combustion melters including one or more of the panels, and methods of using the same. The burner panel includes a panel body including a fluid-cooled portion and a protective non-fluid cooled portion. An exterior surface defined by the fluid-cooled portion, and an interior surface defined by the protective non-fluid cooled portion, exterior and interior referring to an SCM in which the panel is installed. The fluid-cooled portion has at least one burner support passage of diameter (d1) extending from the exterior surface to a seam where the fluid-cooled and protective non-fluid cooled portions meet supporting at least one fluid-cooled SC burner having a fluid-cooled burner tip attached to a burner body protruding away from the seam. The protective non-fluid-cooled portion has a combustion products flow passage of diameter (d2) < (d1). The burner panels promote burner life and melter campaign length.
