Abstract

881,002. Filters. ROLLS-ROYCE Ltd. March 12, 1959 [April 3, 1958], No. 10934/58. Class 46. [Also in Group XXVI] A liquid fuel supply system for a gas turbine comprising a fuel filter and downstream of it a unit, e.g. a fuel supply control unit, in which ice formation is liable to cause malfunctioning, has means arranged on sensing of ice formation in the filter, to heat the unit prior to the heating of the filter for de-icing purposes whereby water formed by melting of ice in the filter flows through the unit without freezing therein. Fuel from a tank 16 is delivered by a booster pump 17 into a fuel pipe 18 containing a fuel heater 19 heated by air tapped from the engine compressor 10 by a conduit 20. The air flow is controlled by a valve 21 operated by a solenoid 21a. The fuel leaving the heater 19 normally passes through a valve 29, a main filter 24 high pressure fuel pump 22, control mechanism 25 and shut off cock 26 to the engine. The system also comprises an auxiliary fuel filter 27. When ice clogs the filter 24, the pressure drop across it increases and causes the collapse of the bellows 34 so that switch 35 is closed. This energises the solenoid 21a which opens valve 21 and allows hot air to be supplied to the heater 19. At the same time the motor 31 is operated to rotate cam 30. This allows spring 29b to urge valve member 29a to the left so that fuel is supplied to the control unit 25 through the auxiliary filter 27. After a period of ninety seconds the cam 30 starts to move the valve member 29a to the right so that for about fifteen seconds both filters are fed with heated fuel. Thereafter, fuel is fed to the filter 24 only. During the periods when hot fuel is fed to the filter 24, the ice in the filter is melted and due to the previous heating of the control unit, the resulting water flows through the control mechanism without freezing. The motor 31 also rotates a cam 30a which closes a holding switch 35a for one revolution of the motor. In a modification, Figs. 2 and 3 (not shown), the control unit and filter have control valves and connecting ducting arranged so that in one setting of the valves the heater is arranged between the filter and the control unit and in the second setting, the filter is arranged between the heater and the control unit.
