Abstract:
A device (1) for storage and conveyance of thermal energy for an energy production system, which device (1) is apt to receive the solar radiation and is based on the use of a modular fluidizable granular bed and a heat exchanger associated thereto. The modular fluidization allows the selective storage of heat or thermal transfer to the exchanger. At the basis of such use, there are the favorable features of thermal exchange of the fluidized beds and the effective convective conveyance of the heat subsequent to the mobility of the granular phase. Both these features are linked to the possibility of imparting a rheological behavior to a granular solid that is comparable to that of a fluid, actually thanks to the fluidization thereof. Such device mainly comprises: - a containment casing (2) provided with one or more cavities receiving the solar radiation (20); - a fluidizable bed of granular particles (3) suitable for thermal energy storage and conveyance, arranged inside the containment casing (2); - one feed inlet for feeding a fluidization gas through the bed (3) of particles by a suitable distributor (21); - a heat exchanger (4) immersed in the fluidizable granular bed and crossed by a working fluid; and - a feeding inlet for a fuel gas (401) as additional thermal input to increase the system management flexibility.

Abstract:
A device (1) for storing and releasing heat energy for an electrical power production plant, the device (1) being apt to receive a concentrated solar radiation and it is based upon the use of a granular fluidisable modular bed, a heat exchanger associated thereto and upon an independent activation of the storing step from the re leasing step. The thermal separation of fluidisation gas from the working fluid, the selective fluidisation of bed zones, the variation of the velocity of heat transfer and additional heat input of fuel gas make the regulation of the generated thermal power extremely flexible. Said device mainly comprising: at least one bed (3, 30) of fluidisable particles, arranged at least partly at receiving surfaces (20) for such radiation; means (14, 142, 21) for feeding a fluidisation gas for the fluidisation of said particles; and heat exchange elements (4) flown through, in use, by an operating fluid and arranged at or in proximity of said bed (3, 30) of fluidisable particles, wherein the overall arrangement is such that, in use, portions (3, 30) of said bed of particles are apt to be selectively moved by the fluidisation gas for storing heat energy received from solar radiation in a storing step and for releasing stored heat energy to said heat exchange elements (4) in a releasing step, and wherein the overall arrangement is such as to allow an independent activation of the heat storing step from the heat releasing step.
