865,762. Generating combustion products under pressure. NAPIER & SON Ltd. July 25, 1958 [July 25, 1957], No. 23819/57. Addition to 812,404. Class 51 (1). [Also in Group XXVI] In a gas turbine power plant, as described in the parent Specification, in which the casings of the compressor and turbine are rigidly connected to one another by a stress-taking structure formed by a series of circumferentiallyspaced generally tubular combustion chambers secured to an annular . plate-like structure, the stress taking combustion chamber assembly is rigidly and permanently secured to the common turbine inlet structure which forms part of the assembly, this assembly being rigidly and detachably connected at one end to the compressor casing and at the other end to the turbine casing. The combustion chamber assembly comprises a series of one-piece tubular sheet-metal members 10 constituting the stresstaking outer walls of the individual combustion chambers, all permanently secured at their upstream ends, as by welding, to a common annular plate-like structure 11 adapted to be rigidly and detachably secured to the outlet flange of the compressor casing 14. The downstream ends of the members 10 are permanently secured, as by welding, at 17 to another plate-like structure 16. Permanently secured, as by welding to the downstream side of the plates 16, is a stress-carrying common turbine inlet structure consisting of an inner sheet-metal member 18 and an outer sheet-metal member 19. The downstream ends of the members 18, 19 are welded to an annular nozzle-ring casing 22 having a flange 34 which is bolted to the turbine casing proper 33. The nozzle-ring casing 22 forms part of the stress-taking structure. Each combustion chamber includes a flame tube 30 supported by spigots 31 and the downstream end-plate 16. |
