FIELD: power engineering. ^ SUBSTANCE: combined power system comprises a gas-turbine engine, a power generator mechanically joined by a shaft with the engine and a source of cold air connected in a gas-dynamic manner with the inlet to the engine. The system additionally comprises a device to prepare and to supply gaseous hydrogen into the engine, which includes a reservoir of liquid hydrogen, a pump of liquid hydrogen supply with a drive, suction and discharge pipelines with stop valves, a heater, an accumulator-gasifier of liquid hydrogen, and also an exhaust header comprising a gas duct with a stop valve, double-fuel burners in an engine combustion chamber, an outlet stop valve and a pressure reducer. The pump at the inlet via a suction pipeline with a stop valve is connected to a liquid hydrogen reservoir, and at the outlet - via a discharge pipeline with a stop valve to the inlet of the accumulator-gasifier. The accumulator-gasifier outlet via an outlet stop valve and a pressure reducer is connected with double-fuel burners of the combustion chamber. The gas duct is connected in a gas-dynamic manner by its inlet to the engine outlet, and by its outlet - via a stop valve - to atmosphere. The heater is arranged in the form of a closed cavity. The liquid hydrogen accumulator-gasifier is arranged in the form of a reservoir and is placed in the heater's cavity. ^ EFFECT: stable production of power of guaranteed level in a wide temperature range of atmospheric air with lower emission of hazardous admixtures with an exhaust gas. ^ 18 cl, 6 dwg |
