  • the collectors 14 have a curved or flat configuration, and are independently adjustable in response to the relative position of the sun 16.
  • one or more of the collectors 14 are controlled by one or more control devices (not shown) to detect and track the relative position of the sun 16 as it moves during a period of time. As such, the collectors 14 periodically adjust according to a current position of the sun 16 to reflect the solar radiant energy 15 (e.g., sunlight) onto the receiver 10, thereby heating the receiver 10 and a heat transfer medium 30 provided to the receiver 10 through an inlet conduit 18 and carried from the receiver 10 through an outlet conduit 20.

  • FIG. 2 illustrates the receiver 10 of FIG. 1 employed within a continuous moving bed (CMB) solar steam generation and storage system 100 for the production of steam during both periods of receipt of increased solar radiant energy (e.g., daylight) and periods of receipt of decreased solar radiant energy (e.g., at night or on cloudy days).
  • the system 100 generates and stores thermal energy for process purposes.
  • the receiver 10 contains a flowing stream of particulate material 30 that absorbs solar radiation 15 as particles within the flowing stream 30 pass through a portion 11 of the receiver 10 and through concentrated beams of solar radiation 15 provided by the solar collector field 14.
  • the particles of the stream of particulate material 30 are comprised of granular particulate having a particle size that is selected to maximize heat storage, while minimizing a temperature difference between surface and average internal regions of the particles.
  • Other factors of interest in selecting the particle size include, for example, aerodynamic considerations to prevent particle loss due to wind currents at the receiver interface, particle thermal transport properties and density, and economic considerations such as, for example, material cost and availability. As can be appreciated, all of these considerations are optimized in selecting preferred particle sizes.
  • the stream of particulate material 30 is passed from the receiver 10 at a temperature in a range of, for example, about one thousand five hundred to about two thousand degrees Fahrenheit (1500 0 F to 2000 0 F, about 816 0 C to about 1093 0 C) into a first chamber 40 such as, for example, a hot storage chamber 40 coupled to the receiver 10.

  • the tube bundle 42 includes a plurality of tubes, one or more of the plurality of tubes having extended surfaces such as, for example, fins, ribs, and the like, to increase a rate at which heat transfers to the tube bundle 42.
  • the fins may also reduce weight and/or cost of manufacture and maintenance of the tube bundle 42 and portions thereof. It should be appreciated that by holding a supply of heated particulate material 30 in the first chamber 40 and permitting it to circulate about and/or flow past the tube bundle 42 steam may be generated and/or regenerated (e.g., superheated and/or reheated) during periods of time when the receiver 10 is receiving a decreased amount or intensity of solar radiant energy 15 (e.g., at night or on cloudy days).
  • a flow rate of the stream of particulate material 30 out of the first chamber 40 is controlled by one or more flow control valves 50 coupled to an output 48 of the first chamber 40 and, for example, downstream of the flow about the steam generating tube bundle 42.
  • the cooled particulate material 30 passes through the flow control valves 50 to a second chamber 60 such as, for example, a cold storage chamber 60.

  • the inventors have found it advantageous to control the flow of particulate material 30 from the first chamber 40 during the periods of increased receipt of solar radiant energy (e.g., during daylight periods) so that the first chamber 40 slowly fills with hot particulate material 30 during such increased receipt periods for current and subsequent use.
  • the inventors have found it advantageous to control the flow of particulate material 30 from the first chamber 40 during the periods of decreased receipt of solar radiant energy (e.g., during night time or cloudy day periods) so that the first chamber 40 maintains within and continues to permit circulation and flow of the hot particulate material 30 past the tube bundle 42 during such decreased receipt periods such that steam continues to be generated, regenerated and/or super heated during such periods.
  • particle flow rates and size of the chambers 40 and 60 are selected to permit continuous operation at full load over, for example, a twenty-four (24) hour time period.
  • the cooled particulate material 30 is passed from the first chamber 40 at a temperature in a range of about three hundred to about five hundred degrees Fahrenheit (300 0 F to 500 0 F, about 149 0 C to about 26O 0 C) into the second chamber 60 coupled to the control valves 50.
  • the particulate material 30 is removed or drained from the second chamber 60 into a transport conduit 70 such as, for example, a pneumatic transport conduit 70, through one or more particulate control valves 72 at an output 62 of the second chamber 60.

Abstract

Système de génération et de stockage de vapeur à l'aide de l'énergie solaire, à lit mobile continu, permettant de générer de la chaleur pour des processus productifs après perte ou baisse de l'énergie solaire reçue. Ce système comprend un récepteur (10) recevant un courant de matériau particulaire (30) qui absorbe l'énergie solaire rayonnante (15) lorsqu'il traverse des faisceaux d'énergie (15) reçus de capteurs (14). Le courant chauffé de matériau (30) pénètre dans une première chambre (40) dans laquelle il chauffe un serpentin (42). La chaleur dégagée par le matériau particulaire (30) est transférée au serpentin (42), l'évaporation de l'eau générant, réchauffant (RH) ou surchauffant (SH) la vapeur (46). Le matériau refroidi (30) traverse une seconde chambre (60). De cette seconde chambre (60), ledit matériau passe dans un cyclone (80) dans le récepteur (10). Le cycle s'achève par l'évacuation du matériau (30) hors du cyclone (80).
