DEVICE TO FEED POWDER FUEL INTO COMBUSTION CHAMBER OF OPEN-TYPE GAS TURBINE ENGINE Russian patent published in 2013 - IPC F02C3/26 

FIELD: engines and pumps.

SUBSTANCE: proposed device comprises fuel tank, screw feeder, combustion chamber, gas turbine, air compressor, driven coupler, and generator 39. Fuel tank bottom is communicated with screw feeder provided with feed tube communicated with combustion chamber. Ninth pipeline feeding compressed air into combustion chamber is provided with flow pickup connected with ratio setting device. The latter is connected with fuel controller connected with drive system. Combustion chamber communicates with gas turbine via pipeline. Gas turbine engine shaft, air compressor shaft, coupler shaft and generator shaft are interconnected. Screw feeder represents a closed design. Powder fuel tank is sealed by cover. In starting the device, compressed air is forced in combustion chamber via third pipeline, high-pressure and high-temperature air tank, and ninth pipeline. Said flow pickup generates signals to be sent to ratio setting device to set relationship and to be sent further to fuel controller and drive system for fuel to be injected into combustion chamber and ignited by ignition system. Closed screw feeder and fuel tank are adequately sealed. Hot gases pass via pipeline into gas turbine to drive it on expansion.

EFFECT: higher efficiency and reliability.
