Abstract

894,470. Generating combustion products under pressure. GENERAL MOTORS CORPORATION. Sept. 28, 1960 [Sept. 30, 1959], No. 33283/60. Class 51 (1). In combustion equipment for burning liquid fuel in an air-stream, for example in a gas turbine engine, and comprising a flame tube disposed within an outer air casing, the flame tube comprises an end dome and a cylindrical section body of equal diameter disposed coaxially with their adjacent edges separated by a gap, an annular strip having axial corrugations and air admission holes being disposed within the flame tube so as to bridge the gap between the dome and adjacent body. The flame tube 10 shown is one of a plurality disposed within the annular air passage 14 formed between the outer and inner air casing walls 12, 15 and comprises an end dome 23, four frusto-conical sections 38, 39, 41, 42, a cylindrical section 43 and an outlet section 17, the cross-section of which changes from circular at its upstream end to a sector of an annulus at its downstream end. The cylindrical portion 30 of the end dome 23 is separated from the upstream end of the adjacent frustoconical section 38 by a gap 51 and a corrugated ring member 50 spans the gap, being secured within the flame tube to the adjacent parts by spot welding. The ring member 50 is formed with air admission holes 52 and a ring 54 is secured to the inner surfaces of the corrugations of the ring member 50, the ring being subsequently divided by a number of axial slots 55 so as to form a plurality of ring portions. An air swirler device 33 is mounted at the centre of the end dome 23 and comprises an inner ring 35, an outer ring 34 and a number of helically disposed vanes 36 therebetween. The tip 29 of the fuel injector 19 is received within the inner ring of the air swirler. The adjacent ends of the frusto-conical sections 38 and 39, 39 and 41, 41 and 42 are secured together by means of corrugated rings 45 which form inlets for cooling air. The downstream ends of the sections 38, 39, 41 are divided at 46 so as to eliminate stresses due to differential expansion, and air inlet openings 58, 59, 61 are formed in the sections. A ferrule 26 is mounted in the tube section 38 to receive an igniter or a support member and adjacent flame tubes are interconnected by means of pipes engaging with the connectors 27. Reference has been directed by the Comptroller to Specification 687,954.
