Abstract
(EN)
Thermal energy storage systems are disclosed in this application. Systems of the inventive subject matter are designed to reduce maintenance requirements by sequestering, for example, corrosive fluids that might otherwise damage difficult-to-fix internal components are kept out of those components by introducing a non-corrosive heat transfer fluid to facilitate heat transfer between a thermal energy storage medium (e.g., molten sulfur) and a potentially corrosive working fluid. Thus, the potentially corrosive fluid is kept out of a thermal energy storage tank containing the thermal energy storage medium, which, by design, is difficult to repair when internal components corrode or otherwise require maintenance.
(FR)
L'invention concerne des systèmes de stockage d'énergie thermique. Les systèmes selon l'invention sont conçus pour réduire les exigences de maintenance par séquestration, par exemple, des fluides corrosifs qui pourraient autrement endommager des éléments internes difficiles à réparer sont maintenus hors de ces éléments par l'introduction d'un fluide de transfert de chaleur non corrosif pour faciliter le transfert de chaleur entre un milieu de stockage d'énergie thermique (par exemple, le soufre fondu) et un fluide de travail potentiellement corrosif. Ainsi, le fluide potentiellement corrosif est maintenu hors d'un réservoir de stockage d'énergie thermique contenant le milieu de stockage d'énergie thermique, qui, par conception, est difficile à réparer lorsque des éléments internes corrodent ou nécessitent une autre maintenance.
