Fluid cooled burner structure

A fuel burner adapted to extend through an opening in a wall of the tunnel connecting a port with the checkers of a regenerative-type glass melting furnace comprising:

• a. an elongated fuel supply tube having an open angled end portion for emitting fuel therefrom;
• b. a tubular jacket concentrically surrounding a portion of said fuel supply tube and extending from said angled end portion;
• c. first and second closure members for closing the ends of the space between the fuel supply tube and said jacket for forming a chamber therebetween, said first closure member having a first planar portion with an aperture therein aligned with the open angled end of said fuel supply tube and extending perpendicularly thereto and a second planar portion extending perpendicular to a portion of said tubular jacket;
• d. a pair of longitudinal vanes oppositely disposed within the space between said fuel supply tube and said jacket and extending from said second closure member to a point adjacent to but spaced from said first closure member;
• and
• e. means for circulating a coolant within the chamber of said jacket.
