| 21 | High capacity/low NOx radiant wall burner | US09949007 | 2001-09-07 | US06796790B2 | 2004-09-28 | Demetris T. Venizelos; Wesley Ryan Bussman; Ralph Robert Hayes; Jesse S. Chambers; Roger L. Poe |
| A burner assembly for a radiant burner includes a burner tube structure in the form of an elongated burner conduit having spaced inlet and outlet ends. The conduit is adapted and arranged for directing a fuel lean gaseous mixture comprising a portion of the total fluid fuel to be combusted and oxygen therealong from the inlet end to the outlet end. The assembly also includes a main burner nozzle at the outlet end of the conduit, which nozzle has a central axis, a wall extending around a centrally located chamber therein, and a downstream end spaced from the outlet end of the conduit. The main burner nozzle is arranged and adapted for receiving the mixture from the conduit in the chamber and redirecting the same through a plurality of apertures in the wall and into a combustion zone in a direction transverse to the axis and at a velocity which is greater than the flame speed of the gaseous mixture. The apertures are distributed circumferentially around the wall, whereby the mixture is directed without substantial recirculation and with minimal pressure drop through said apertures and into the combustion zone in the form of a generally round flat pattern which is detached from the nozzle, surrounds the wall and extends outwardly across a radiant surface of a burner tile. The burner also includes an elongated fuel tube extending in a direction generally parallel to the axis, and the fuel tube has a downstream end portion. A secondary fuel nozzle includes a secondary fuel port on the downstream end portion of the fuel tube, which secondary fuel port is located and arranged so as to deliver secondary fuel to a position which is on the opposite side of the fuel pattern from the radiant surface and sufficiently remote from the combustion zone to permit the same to become intermixed with flue gases before entering said combustion zone. | ||||||

| 31 | Gas burner for flame adherence to tile surface | US881772 | 1978-02-27 | US4220444A | 1980-09-02 | Robert D. Reed; Hershel E. Goodnight |
| A gaseous fuel burner for enhanced flame adherence to a tile surface in a furnace, comprising a gas burner tube having a nozzle at its end, including a plurality of radial orifices circumferentially spaced in a transverse plane. A cylindrical combustion air plenum is coaxial with said burner tube, and means are provided to supply combustion air to said plenum at a selected super-atmospheric pressure P1. There is a circular concentric opening in the wall of the plenum and a short length of air tube welded to the opening, which is inserted into an opening in the furnace tile. A plurality of curved vanes are provided, and means to lead air from the pressurized plenum through the vanes to provide a rapidly spinning air flow which moves helically along the air tube into the tile and into the furnace. The central opening of the tile is flared in an arcuate manner. There is sufficient pressure drop between the air plenum at P1 and inside of the air tube P2, after passage through the vanes, of the order of 0.8 W.C. so that a tangential air velocity of as high as 100 feet per second is possible. This rapidly spinning air volume has fuel injected into it under pressure through the radial orifices, and flows into the furnace in an expanding spiral flow along the arcuate portion of the tile. Because of the high tangential velocity of the air, gas and flame, the pressure at the face of the tile is low and the flame is held in close contact with the tile causing rapid heat transfer to the tile which then radiates into the furnace area. | ||||||
