| 摘要 |
A thermal electric power generating unit using pressurized hot air together with superheated steam, which is useful for storing superfluous electric energy of thermal power plants in the form of compressed air during an off-peak load period, and for regenerating electric power by using the thus stored compressed air during succeeding peak load periods. The unit comprises a means for producing compressed air, a boiler to produce superheated steam, a drum within the boiler for heating the compressed air, a special injection nozzle to simultaneously inject said superheated steam and the pressurized heated air, a gas turbine to be driven by gaseous mixture jets from said nozzle, and an electric generator driven by said gas turbine. The injection nozzle comprises a hollow toroidal member having adjacent but separated input and output orifices, and having a heating coil disposed therein for maintaining the gas at a desired temperature as it is being discharged.
