<p>An improved power plant employing a combination of compressed air storage and saturation (simultaneous heating and humidification) of compressed air is disclosed. The power plant (20A) includes a combustor (26) which provides hot gas for driving a turbine (24). The turbine (24) is used in conjunction with a generator (34) to generate electrical power. The power from the turbine (24) is accessible by a compressor system (40) during low power demand periods. The compressor system (40) is used to compress air which is stored in an air storage chamber (52). The compressed air from the air storage chamber (52) is used by the combustor (26) during high power demand periods, while the compressor system (40) is shut down, to provide compressed combustion gas to the turbine (24). To enhance the efficiency of the plant, while further lowering the capital cost of the plant, a saturator (60) is positioned between the storage chamber (52) and the combustor (26). The saturator (60) receives compressed air from the storage chamber (52) and simultaneously heats and humidifies it. The resultant heated and humidified compressed air is then conveyed to the combustor (26), typically after further heating by a recuperator (70).</p> |
