Abstract
758,709. Gas turbine plant. HOLLEY CARBURETOR CO. Dec. 10, 1954, No. 35781/54. Class 110(3) [Also in Group XXIX] A gas turbine plant comprising an air compressor feeding a combustion chamber and a turbine has a plurality of hollow bars across the inlet of the compressor with elongated slots on their downstream edges, a passage for conveying hot gases from the turbine exhaust to the interior of the bars and valve means controlling the flow in the passage which is responsive to a reduction in air flow or air pressure or both between the compressor and turbine as the result of ice formation on the compressor air inlet. A compressor 26 supplies air to a combustion chamber 28 feeding a gas turbine 18 driving the compressor. A screen 12 located in the compressor entry has a series of vertical streamlined tubes 11 arranged on its upstream side to which gases from the turbine exhaust space 16 are led by a passage 14. The tubes 11 are slotted at the back so that the gases impinge directly on the screen 12. A pitotstatic tube 30 is arranged in the entry to the combustion chamber 28. The differential pressure across the pitot-static tube 30 is applied to a spring loaded diaphragm 36 which is connected to an electrical contact 48 so that when the air flow is above a predetermined value the contacts 48, 50 are separated. A further spring loaded diaphragin 38' is actuated by the static pressure in the pitot-tube only. This diaphragm is connected to a movable contact 44 which engages a stationary contact 46. The contacts 48, 50 and 44, 46 are arranged in parallel in a circuit which energizes a solenoid 60 controlling a throttle valve 70 in the passage 14. The arrangement is such that, when the manually operated switch 54 is closed, if either the air flow or pressure in the combustion chamber falls below a predetermined value due to icing on the screen 12. the solenoid 60 is energized and the valve 70 operated to allow hot gas from the turbine exhaust to pass through the passage 14 and tubes 11 so as to melt the ice on the screen.
