Abstract
723,830. Vapour burners. ARMSTRONG SIDDELEY MOTORS, Ltd. Aug. 6, 1953 [Sept. 13, 1952], No. 23056/52. Class 75 (1) [Also in Group XII] In a flame stabilizing device for use in an exhaust reheat system of a gas turbine jet propulsion engine, the supply of fuel for the stabilizing device is introduced into and near one end of a duct 19 disposed in the main gas flow and having adjacent the fuel inlet 22 an opening 24 through which a small amount of the main gas flow can enter, the opposite end 20 of the duct communicating substantially centrally with the upstream end of the stabilizer casing 14. The casing 14 is supported by radial struts 15 which are'secured to the jet pipe 13 by means of bolts 17, and in Fig. 1 the duct 19 extends radially and is in line with one of the struts 15. In a second embodiment, the duct extends co-axially upstream from the stabilizer casing and the fuel supply pipe is led radially across the jet pipe. The fuel passing through the duct 19 is vaporized and enters the casing 14 through swirl vanes 27. Gaseous fluid flowing in the jet pipe enters the casing 14 through swirl vanes 30 which impart swirl in a direction opposed to that of the vanes 27. The means for causing ignition of the fuel within the stabilizer casing so as to form the pilot flame and the means for supplying the main reheat fuel are not shown. In further embodiments, the vaporized fuel and gas issuing from the duct 19 does not pass through swirl vanes 27, but impinges on a flat baffle plate which causes turbulence and directs the mixture radially outwords. In a further embodiment, the vaporized fuel and gas issues through swirl vanes 27 but the gas stream entering the casing 14 impinges on a baffle plate which thereby causes turbulence. Specification 674,641 is referred to, and Specification 705,772 is referred to in the Provisional Specification.
