Compressed air energy storage power plant has Stirling engine containing cold regions and hot region, which is operated using exhaust air from air turbine and exhaust gas from heat exchanger

摘要

The power plant has a compressed air reservoir (1) which is connected to air turbine (3) via a heat exchanger (2). A gas turbine (4) is connected to the heat exchanger, so that the hot exhaust gas from the gas turbine is configured to provide heat energy to the air flowing from the compressed air reservoir to the air turbine. A Stirling engine (5) containing cold region (5'') and hot region (5'), is operated using the exhaust air from the air turbine and the exhaust gas from the heat exchanger. An independent claim is included for method for operating compressed air energy storage power plant.
