Abstract

1341223 Gas turbine combustion equipment GENERAL ELECTRIC CO 12 Jan 1971 [9 April 1970] 1432/71 Heading F1L [Also in Division F4] A device 34 for introducing a swirling fuel/air mixture into the combustion chamber 14 of a gas turbine engine comprises a scroll housing having an inlet 36 receiving air from compressor 28 and liquid, gaseous or solid fuel e.g. through pipe 44, the mixture leaving the scroll outlet 38 as a vortex 40. Formation of the latter is assisted by swirl vanes 58. A further stream of air is introduced past vanes 64 with a swirl 67 of the same or opposite direction to that of vortex 40, the further stream assisting dispersion of any fuel which collects on an annular sleeve extending from outlet 38. To prevent recirculating combustion gases 82 from impinging upon the upstream wall 50 of the scroll and causing overheating and carbon build-up, a stream of swirling air 94 is introduced into the scroll through a central opening 86 from a chamber 92 defined by a dished cover 88. Air enters chamber 92 with a swirling motion through circumferentially spaced inclined openings 90 in cover 88, the swirl being in the same direction as vortex 40. In a modification, spaced openings 90 are replaced by a single larger hole.
