Abstract

694,484. Generating combustion products under pressure. ROLLS-ROYCE, Ltd. June 8, 1950 [June 30, 1949], No. 17383/49. Class 51(i) [Also in Group XI] In an air jacketed type of combustion chamber in which the flame tube has an annular, sharplydivergent inlet wall portion 26, an annular' divergent ring 29 is disposed within the inlet wall 26 to define therewith an annular convergent duct 30 through which air is delivered to the combustion space within the flame tube. A sleeve 33 is provided between the ring 29 and the fuel injector 22 to form an annular passage 35 having swirl vanes 34 for a subsidiary flow of primary air, and an annular passage adjacent the fuel injector for a further subsidiary flow of primary air. The ring 29 is supported from the inlet wall 26 by means of tubular spacer members 31 and bolts 32. The invention is applicable to combustion chambers comprising a series of flame tubes either each in its own air casing or all in a common annular air casing, or combustion chambers comprising an annular flame tube in an annular air casing. Specification 694,483, [Group XI], is referred to.
