Title: Improvements in or relating to a gas turbine
IPC: F02C5/12
Filed: 1947-06-20
Abstract: 633,011. Generating combustion products under pressure. LASLEY, R. E. June 20, 1947, No. 16330. Convention date, Dec. 29, 1945. [Class 51 (i)] [Also in Group XXVI] Combustion products for use in a gas turbine are generated in two interconnected explosion chambers 10, 11, Fig. 1, which operate at different pressures. The chambers are supplied with air from a two-stage compressor 83, 85 through valves 21, 22. Vaporized fuel with some air is injected into the air in chamber 10, to the right of a perforated partition 70, by a nozzle 59. The mixture is ignited by a spark at plug 72 and the pressure of the explosion drives the air in the part of the chamber 10 to the left of the partition 70 through the channel 13 at increased pressure into the chamber 11. Vaporized fuel is injected into this air stream by a nozzle 57 and the stream passes into the chamber 11 through a valve 14 which is opened by the pressure of the stream. Vanes 16 impart a swirl to the stream to secure a mixing of the fuel with the air already in the chamber 11 and the whole is ignited at a plug 72. The high-pressure products of combustion pass out into pipe 75 and entrain the low-pressure products passing out of chamber 10 and the mixture goes to a turbine which may have oppositely-rotating wheels 76, 77. In an alternative form, the combustion products from the two chambers are not mixed, the high-pressure gas passing to a high-pressure turbine stage and the low-pressure gas, to a lowpressure stage of the same turbine. Two pairs of combustion chambers are shown in Fig. 4 and the plant shown in Fig. 1 has four pairs. The injection of the fuel is controlled by two valves 60, Fig. 2, operated by means of diaphragms 67 and hydraulic columns 129, 128 by cam-actuated plungers 125, 124 in casings 111, four of which are shown in Fig. 1, and the sparks are controlled by a distributer 120. The cams 106, 107 and the distributer are driven by a turbine wheel 98 through gearing 100 and a shaft 101. The turbine is driven by the stream of air from the compressors 83, 85 on its way to the airdistributing main 24 Fuel from a tank 36, Fig. 1, and air from a pipe 38 are passed by a pump 39 to a vaporizer 42 which comprises a coil 44. Fig. 4, in a part of the turbine exhaust pipe 43. The vapour passes to a chamber 47 from which it goes to the valves 60 in the casings 63. A thermometric control is provided by a rod 50 which operates a flap 48 to vary the amount of exhaust gas passing over the coil 44. Specifications 464,323 and 569,579, [Group XXVI], arc referred to.
