Patent ID: 8276359

Claim:
A gas-turbine plant comprising: a gas-turbine engine having an air-processing device, a compressor, and combustion chambers operating on a cryogenic gas fuel to supply combustion gases to an exhaust tube, the gas-turbine engine driving actuating units; a fuel system coupled to the combustion chambers; a fuel heater mounted in the exhaust tube of the gas-turbine engine; wherein the fuel system having fuel pipelines and a device for supplying and controlling fuel to the combustion chambers, the device is connected to a fuel pipeline from a reservoir for storing the cryogenic gas fuel and which is connected to the combustion chambers by fuel pipelines via the fuel heater; a lubricating system for friction units of the gas-turbine engine and actuating units, wherein the lubrication system includes a lubrication loop for the friction units of the gas-turbine engine having a fuel-oil cooling heat-exchanger, a supply pump and an oil tank and a lubrication loop for the friction units of the actuating units having a fuel-oil cooling heat-exchanger, a supply pump and an oil tank; wherein a first fuel pipeline of the fuel pipelines connects the device to the fuel-oil cooling heat-exchanger of the lubrication loop of the actuating units and the fuel heater, and a second fuel pipeline of the pipelines connects the device to the fuel-oil cooling heat-exchanger of the lubrication loop of the gas-turbine engine and the fuel heater.
