Abstract

635,512. Burners. BEVAN, A. W., and BEVAN, N. J. Dec. 17, 1947, No. 33213. [Class 75 (i)] [Also in Groups XII and XXVI] A burner for burning fuel in a stream of air travelling at a speed higher than the speed of flame propagation in the fuel-air mixture, comprises a tubular body 10 having near its forward end, which constitutes the air inlet to the burner, an inlet 16 for gaseous or vaporized fuel, and having its outlet end 22 shaped to cause the boundary layer of combustible fluid mixture to break away from the wall of the body 10 and form back flow vortices around the periphery 26 of the issuing stream of combustion gases. The fuel inlet 16 may be annular so that the fuel flows between inner and outer streams of air, and the fuel may consist of vaporized liquid, or where the burner is used in a ram jet, as shown, of a gas such as propane, butane, or a mixture thereof. Fan blades 23 assist the mixing of the fuel and air, and the mixture is ignited by a sparking plug 27 or a catalytic or other ignition device. The back flow vortices enable a flame to be maintained in the annular zone 26, and in order to ensure the formation of back flow vortices the cone angle of the outlet 22 should exceed 10 degrees. A plurality of burners may be mounted in the air duct of a single ram jet at the tip of a rotor blade of a helicopter.
