  • thermosolar technology plants Other types normally used for thermal storage in thermosolar technology plants are based on the use of two molten salt tanks and pressurized water storage systems.
  • the thermal storage system based on sensible heat is carried out by varying the temperature in stored and deposited gravels specifically, using its heat capacity.
  • the storage system is based on the arrangement of three types of gravel with the following characteristics:
  • the system consists of two circuits for the transfer of thermal energy: a LOAD circuit, and a DISCHARGE circuit.
  • LOAD circuit For the LOAD circuit, a series of sections of pipes are circulated longitudinally through the gravels through which the fluid coming from the receiver is circulated at high temperature, in order to transfer the thermal energy captured by the concentrator system to the gravel, which increases its temperature.
  • the DISCHARGE circuit is analogous to the previous one, consisting of a series of sections of pipes through which the fluid is circulated at a low temperature, which increases its temperature by the transfer of thermal energy from the gravels previously heated by the charging process.
  • WATER as fluid in the discharge circuit, and the control of the flow and pressure parameters, allows the operation as DIRECT STEAM GENERATOR during the process and the same DISCHARGE conduction.
  • a geothermal membrane surrounds the entire system, whose function is to insulate the humidity outside the interior gravel.
  • the arrangement of the CHARGE and DISCHARGE pipes is distributed through the intermediate layer (graphite), which thus allows a high thermal transfer and distribution of energy for storage in high density gravels.
  • CONTRAFFUJO in the loading and unloading facilitates, in the way of DISCHARGE by means of DIRECT STEAM GENERATION, to achieve a percentage of drying of the steam generated high and as close as possible to the saturated saturated vapor, by means of the regulation of the different flows and flows. .

  • the described thermal storage system is susceptible of industrial application in any process in which it is necessary to store thermal energy for its later use over time.
  • the main application lies in those processes in which thermal energy is generated in periods under temporary conditions that impede its manageability. This is the case of solar thermal plants in which the energy source comes from solar radiation, and is therefore subject to the determined hours in which solar radiation is available and which vary according to the different months of the year. weather conditions and other elements of an atmospheric nature.
  • a thermal storage system as described in this document allows the thermal energy from a solar radiation collector system to be stored, for its later use in a power cycle [or other industrial use] in the conditions specified by the user, allowing thus the manageability of the solar energy captured, and thus prolonging the operation of the solar thermal plant according to the design and thermal capacity of the storage system.

Abstract

L'invention s'inscrit dans le domaine de la gestion de l'énergie, plus concrètement dans le procédé de stockage et d'accumulation d'énergie thermique par chaleur sensible. Son implication directe intervient dans la technique de production et gestion des énergies renouvelables, spécifiquement dans les énergies renouvelables qui utilisent le soleil comme source primaire d'énergie (thermosolaire), l'application peut être étendue à n'importe quel procédé industriel qui nécessite un système de stockage thermique gérable. L'invention concerne un système de stockage thermique basé sur la chaleur sensible, utilisant pour cela les propriétés physiques de différents types de graviers spécifiquement distribués. Ledit système peut être utilisé dans les procédés dans lesquels il est nécessaire de stocker de l'énergie thermique pour son utilisation ultérieure de manière gérable, et de manière spécifique dans le domaine des énergies renouvelables qui utilisent l'énergie du soleil comme source principale d'énergie pour sa conversion ultérieure en énergie électrique, comme c'est le cas de l'énergie thermosolaire. Le système de charge et décharge de l'énergie thermique stockée est obtenu au moyen d'un réseau de tuyaux distribués uniformément et en couches, et qui transfèrent l'énergie thermique générée aux graviers, en fonction de leur coefficient de conductivité thermique et de la densité des matériaux.
