Abstract

1335746 Gas turbine combustion equipment GENERAL ELECTRIC CO 19 April 1971 [25 May 1970] 22400/71 Heading F1L Gas turbine engine after-burner flameholder consists of an annular V-shaped gutter 32 having its apex in an upstream direction, links 42 connected at their downstream ends to the apex of the gutter and spaced circumferentially therearound and mounting means 48 pivotally connected to the upstream ends of the links and aligning the pivot axes of the links and the bisector "x" of the gutter in the direction of the hot gas flow theretoward in the "hot" condition of the afterburner, thereby reducing any tendency to twist the gutter when its material strength is weakest. Exhaust gases from a compressor/combustion chamber/ turbine unit flow along an annular duct formed by an engine casing 24 and central plug 26. Fuel is injected into the gas stream from bundles of tubes 30, and the flame is stabilized by a number of annular sheet metal gutters 32. Mounting lugs 38 extend through openings 36 in the gutters and have curved wings 40 which are brazed to the gutter. The upstream end of each lug is pivotally connected by a pair of links 42 to a beam 48. The radially outer end of the beam is pivotally attached to a lug 52 attached to the outer casing 24 of the engine. The beam is also supported by a link 54, one end of which is pivotally connected to the beam and the other end of which is pivotally connected into a bracket 60 mounted on a central plug 26 of the engine. When the afterburner is in operation, expansion of the casing 24, plug 26 and gutters 32 is accommodated by the links so that the gutters take up a position in which the bi-sector is aligned with the pivots 44 and 46. and with the direction of the hot gas stream.
