Title: Gas turbine power plant
Inventor: PEARSON RONALD DENZIL
IPC: F01D5/18
Filed: 1953-09-17
Abstract: 774,500. Gas-turbine plant. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Dec. 17, 1954 [Sept. 17, 1953], No. 25766/53. Class 110 (3). [Also in Group XII] In a gas-turbine engine the whole or most of the dilution or cooling air is admitted to the interior of hollow stator guide vanes 6, each having a slot 6a extending along its leading edge for the discharge of the air. The combustion chamber of Fig. 1 comprises a cylindrical flame tube 2 disposed in a cylindrical outer casing 1, the downstream ends of the flame tube and casing each merging into the shape of a segment of an annulus, the discharge ends of the plurality of combustion chambers forming a complete annulus. Two concentric rings 4, 5 are supported by struts 9 to form the outer and inner walls of an annular nozzle assembly. Each of these walls is formed with openings in which the ends of hollow tubular or sheet metal inlet guide vanes 6 are mounted. The leading edge of each vane 6 is formed along its length with a slot 6a so that dilution air flowing between the flame tube and outer casing enters the hollow guide vane from both ends, reverses in direction to discharge into the gas stream issuing from the flame tube, and then again reverses in direction to flow and mix with the combustion gases. The invention is also applicable in the case of combustion equipment comprising an annular outer casing containing either a series of tubular flame tubes or a single annular flame tube. The trailing edge of each stator guide vane 6 may also be open so that some cooling air may issue therethrough, a strip of corrugated material being disposed in the opening to form a series of air outlets. In Fig. 7, air from a compressor enters the combustion equipment at 22, combustion air flowing in an upstream direction to enter the flame tube at its upstream end, while the dilution air flows straight into the hollow stator guide vanes 6. The height of the guide vanes may be reduced towards the trailing edges by suitably sloping the walls 7, 8. Specifications 723,015 and 774,499 are referred to.
