Abstract
Submerged combustion burners having a burner body, a burner tip connected thereto, and a protective cap and/or cladding layer. Submerged combustion melters including the burners and methods of using them to produce molten glass. 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 tip body is connected to the burner body at ends of the external and second internal conduits. The burner tip and protective cap and/or cladding layer include a generally central flow passage for a combustible mixture, the flow passage defined by an inner wall of the burner tip and protective cap.
