Device, plant and method with high level of energy efficiency for storing and use of thermal energy of solar origin

摘要

A device for storing and releasing heat energy for an electrical power production plant is described. The device has: at least one bed of fluidisable particles, arranged at least partly at receiving surfaces for such radiation; means for feeding a fluidisation gas for the fluidisation of said particles; and heat exchange elements flown through, in use, by an operating fluid and arranged at or in proximity of said bed of fluidisable particles.
