Abstract

875,342. Generating combustion products under pressure. GENERAL MOTORS CORPORATION. March 23,1960 [July 8, 1959], No. 10264/60. Class 51 (1). [Also in Group XXVII] A gas turbine engine combustion chamber comprises an outer casing 13 and a flame tube 16 disposed therein, and a hollow open-ended cylindrical guide member 32 having air inlet openings 36 is provided so as to extend across the air passage 12 between the casing and the flame tube. An igniter 20 having an outer cylindrical earth electrode with air inlet openings and an inner high-tension electrode is disposed within the guide member 32, so that the end of the igniter projects through the open end of the guide member into the flame tube. An annular space is provided between the igniter and the guide member for circulation and discharge into the flame tube of air from the admission hole. A ferrule 31 is secured within an opening in the wall of the flame tube and a mounting flange 26 is secured to the outer casing 13. The guide member 32 with its support flange 34 is then inserted into the ferrule 31, the flange 34 abutting against the flange 26. The igniter 20 comprising an outer shell 22 having air inlet openings 38 and an inner portion 23 of reduced diameter, a support flange 25 and a high-tension electrode 27 mounted within a ceramic insulator 28, is then inserted into the guide 32 so that the flange 25 abuts against the flange 34 and the end portion 23 and electrode 27 project into the flame tube. The parts are secured together by means of bolts 24. Cooling air entering through the openings 36 flows through the annular space between the igniter 20 and the guide member 32 into the flame tube while a further portion passes through the openings 38 into the annular space within the igniter between the outer shell 22 and the ceramic insulator 28. The combustion equipment shown comprises a series of flame tubes 16 disposed within an annular air space formed between the outer casing 13 and an inner casing, only two of the flame tubes being provided with igniters 20. The flame tubes are interconnected by interconnector pipes for propagation of flame therebetween. Those flame tubes not provided with igniters have guide members 40 as shown in Fig. 4, the guide members being similar to those shown in Fig. 2 except that they have tubular members 44 secured therein which members may be considered to be dummy igniters. Cooling air entering through inlets 36 discharges through openings 43 into the flame tube.
