Abstract
843,928. Gas turbine fuel systems. ROLLSROYCE Ltd. Aug. 14, 1958 [Aug. 20, 1957], No. 26331/57. Class 110 (3). [Also in Group XXIX] A fuel heating system for a gas turbine comprises a fuel pump 16 delivering to a heat exchanger 18 supplied with heated air from the compressor 11 through pipes 23a, 23b, the flow of air being regulated by a gate valve 31 actuated by a fluid-pressure servomotor 24 controlled by a temperature-responsive element 25 in the outlet pipe 17b from the heat exchanger. The servomotor comprises differential pistons 37b, 38b working in cylinders 26, 27, and between which the gate valve 31 is mounted, the piston 38b carrying a tapered plug 38d movable within an orifice 39 between a chamber 28 and that portion of cylinder 27 to the right of piston 38b. In operation the air from inlet pipe 23a passes into the space between pistons 37b, 38b, then via a passage 38e in piston 38b and plug 38d into chamber 28, through orifice 39 and a pipe 40, and finally discharges into atmosphere through a second orifice 25c, the area of which is controlled by a needle valve 25b whose setting is varied in accordance with the temperature of the fuel in the outlet pipe 17b. The variation in the pressure of the air acting on the right-hand surface of piston 38b consequent upon movement of needle valve 25b results in movement of the differential piston unit and gate valve 31, by which the flow of hot air through pipes 23a, 23b is regulated, the arrangement being such that movement of tapered plug 38d in orifice 39 tends to restore the pressure of the air in the right-hand portion of cylinder 27 to its original value upon any variation thereof due to operation of needle valve 25b. Leakage past piston 38b is minimized by providing the latter with a recess 27b communicating with atmosphere through a passage 38f, at the end of which is a variable orifice 41, by adjustment of which the pressure in recess 27b may be made equal to that on the right of piston 38b.
