ABSTRACT:
Gas turbine with a bottoming air turbine cycle. This system comprises a gas turbine and a bottoming air turbine cycle system. The latter includes a gas-to-air heat exchanger, compressed air aftercooler, an air compressor, a hot air turbine, and a cold air turbine. High temperature exhaust gases of the gas turbine pass the heat exchanger heating compressed air delivered by the air compressor. Then hot air expands in the hot air turbine. Part of the air from the compressor is cooled in the aftercooler, and then expands in the cold air turbine. Hot and cold air turbines drive the air compressor and an electric generator or other consumer of mechanic power. After the cold air turbine, air temperature is lower than the ambient temperature. Using it, refrigeration can be provided, including cooling gas turbine compressor inlet air. In this mode, the gas turbine compressor consumes air having stabilized low temperature and stabilized pressure. A special peak load mode of the gas turbine is also available.
