  • Air-heating gas burner
    Patent number: 6921261
    Abstract: A burner (10, 210, 310, 410) including a fuel manifold (12, 212, 312, 412), perforated air-mixing plates (14, 16, 214, 218, 414) coupled to the fuel manifold to define a fuel-air mixing region (22, 473) therebetween above the fuel manifold, and unperforated air-deflector wings (24, 26, 216, 236, 428). Each unperforated air-deflector wing is coupled to one of the perforated air-mixing plates such that each unperforated air-deflector wing extends upwardly from and at an angle to the perforated air-mixing plate to which it is coupled.

  • Distribution cone for pulverized coal burners
    Patent number: 5526758
    Abstract: A distribution half-cone for a granular or pulverized fuel, typically coal, burner is mounted within a burner nozzle thereof proximate to a burner elbow of the burner to provide a space or gap between an inner wall of the burner nozzle and the outer surface of the distribution half-cone of approximately 3/16 inch to prevent fuel roping and to minimize the pressure drop in the burner. The inlet of the distribution half-cone is formed as a sharp edge nozzle to minimize pressure drop in the burner.
