Thermal storage facility especially suitable for concentrating solar power installations

摘要: A thermal storage facility is provided for storing energy at elevated temperature. The comprises an enclosure retaining a medium; primary heat transfer surfaces transferring from circulating fluid; and secondary the medium to steam pipes associated with power generation facility. metallic phase change material, preferably having melting temperature above 500 °C, interposed between surfaces. fluid liquid over extended range of temperatures ambient through maximum operating in excess point material. selected molten alkali metal or alloys metals. invention extends solar installations incorporating one more such facilities.
