Abstract

1,092,589. Burners. VAPOR CORPORATION. July 8, 1966 [Nov. 5, 1965], No. 30727/66. Heading F4T. A burner assembly adapted to be mounted in the throat 24 of a combustion chamber 23, said assembly comprising a tubular holder 32 for atomizing nozzle 57 axially aligned with throat 24, a main air spinning core 27 for directing air to a first point on the axis of the nozzle holder, a secondary air spinning core 28 for directing air to a second point on said axis closer to the nozzle, the air flow through the main core being greater than through the secondary core, and the burner assembly being separated from the throat by an air gap 37. The cores 27, 28 are each formed from two frusto - conical components, and they are inclined at 45 degrees and 15 degrees to a plane at right-angles to the nozzle holder axis. The core components are interconnected by vanes, Figs. 6 and 8 (not shown), which extend at 15 degrees to a tangent along the innermost periphery of the inner frusto-conical component. The burner assembly includes a mounting ring 25 having extending therefrom a plurality of mounting tubes 26 which receive the cores 27, 28. The main core 27 is filled by refractory material 54 through which passes the holder 32, and holders 31 and 33 which mount a sight glass unit 55 and pilot burner with scanner unit 56 respectively. An annular spacer ring 29 separates the cores 27, 28. Air is supplied to the burner assembly from a plenum housing, Fig. 2 (not shown), which surrounds the assembly and the combustion chamber.
