Submergible combustion burner

A submerged combustion melting apparatus, comprising:

• a melting chamber for containing a molten pool, said melting chamber having an orifice formed in a wall thereof;
• and
• a burner positioned at the orifice to inject a flame into the melting chamber, the burner comprising:
• a first tube having a first longitudinal bore;
• a second tube having a second longitudinal bore, said second tube being disposed within said first longitudinal bore such that an annular space is defined between the second tube and the first tube;
• a nozzle formed at a tip of the second tube, said nozzle having an inlet face facing the second longitudinal bore and an outlet face in opposing relation to the inlet face, said nozzle comprising a plurality of side holes formed therein, said side holes extending from the inlet face to the outlet face, said side holes being slanted outwardly relative to a longitudinal axis of the nozzle and being in communication with the second longitudinal bore;
• and
• a plurality of protuberances protruding laterally from an exterior of the nozzle, each of the protuberances corresponding laterally in position to one of the side holes, wherein the plurality of protuberances is provided by corners of a polygonal flange attached to the exterior of the nozzle, wherein the corners of the polygonal flange are radially oriented relative to the center of the polygonal flange.
