Title: Improvements in or relating to gas turbine power plants
Inventor: RUBBRA ARTHUR ALEXANDER
IPC: F02K1/80
Filed: 1952-10-03
Abstract: 746,901. Gas turbine plant. ROLLSROYCE', Ltd. Oct. 1, 1953 [Oct. 3, 1952], No. 24899/52. Class 110(3) [Also in Group XXVIII] A gas turbine plant comprises a working fluid duct structure which is liable to be heated in operation and which includes two adjacent duct parts joined by an expansible joint which includes two seals in series in the leakage path through the joint, fuel collector means formed on one only of the duct parts and having a collecting space connected in the leakage path between the two seals to receive leakage fuel, and means to deliver the leakage fuel to within a working fluid passage of the plant. Fig. 8 shows an expansible joint between the wall 13a of the turbine exhaust cone and the inlet end of the jet pipe 14, in which a ring 17 carried by the jet pipe 14 surrounds a ring 16 carried by the wall 13a, with sealing rings 22, 23 engaging circumferential grooves 18, 21 respectively. Two axially-spaced rows of circumferentiallyspaced slots 29 in the ring 17 are arranged to maintain communication with two circumferential grooves 19, 20 in the ring 16 over a limited range of relative sliding between the rings 16 and 17. Unburnt fuel which collects in the jet pipe 14, as when the plant is started while the aircraft is airborne, may leak past the sealing ring 23 and pass through the slots 29 into an annular chamber 24 and thence through holes 28 into a sump 27. The passage of jet gases through a venturi 50 draws the fuel from the sump 27 through a standpipe 46 into the jet pipe 14, where it is carried away and dispersed by the jet gases. The relative movement of the rings 16, 17 is limited by a pair of keep plates 33, Fig. 4, one on each side of the jet pipe 14. The keep plates are of channel form and straddle local flanges 34, 36 on the rings 16, 17 respectively. In the modification shown in Fig. 7, the ring 16 has a portion 16a which projects between rings 40, 45 carried by the jet pipe 14. Sealing rings 41, 43 are received in circumferential grooves 42, 44. The chamber 24 and sump 27 are connected by a pipe (not shown) to a high-pressure stage of a compressor forming part of the gas turbine plant. The resultant air pressure within the sump 27 forces the fuel up the standpipe 46 into the jet pipe 14. Each of the two alternative methods of drawing or forcing the fuel through the standpipe 46 may be applied to either embodiment. The invention may be applied to the joint between two duct parts at the downstream end of a combustion chamber of the plant, or to a joint between two parts of the jet pipe. Specification 746,902 is referred to.
