Abstract:
A high efficiency gas turbine power generator comprising:an ultra high pressure combustor having a gas intake, an internal cogeneration chamber with fuel injection, steam injection and a motive gas transfer pipe; a one-stage, ultra high pressure gas turbine connected to the motive gas transfer pipe of the combustor, the ultra high pressure gas turbine having a central rotor; a first electric motor-generator having a shaft connected to the central rotor of the ultra high pressure gas turbine; a counter rotating compressor having a central rotor connected to the shaft of the first electric motor and a counter rotating peripheral rotor around the central rotor; said second electro motor-generator having a shaft connected to the peripheral rotor of the counter rotating compressor; a counter rotating gas turbine having a central rotor and a counter rotating peripheral rotor around the central rotor; said second electric motor-generator having a shaft connected to the peripheral rotor of the counter rotating gas turbine; an electric motor driven compressor having a central rotor and a compressed gas output conducted to the gas intake of the ultra high pressure combustor; and a third electric motor-generator having a shaft connected to the central rotor of the electric motor driven compressor and to the central rotor of the counter rotating gas turbine, wherein the electric-motor generators at start-up initially operate as motors driving the counter rotating compressor and electric motor driven compressor and after start-up operate as electric power generators.
