High-temperature thermal storage device with induction heating and molten metal, and thermal storage-composite system

摘要

A high-temperature thermal storage device has a crucible, an induction heating device, a tubular duct in which a liquid and/or gaseous heat carrier flows, and an electrically conductive storage medium filled into the crucible that fills the crucible at least partially. The induction heating device, when electric energy is applied, heats the storage medium. The tubular duct passes at least partially through the storage medium. The storage medium is a molten metal and the thermal storage device has an operating temperature exceeding 700° C. The thermal storage device readily provides steam, be it saturated steam or superheated steam, fulfilling all parameters required for the operation of a conventional thermal power station.
