ALMACENAMIENTO DE ENERGIA TERMICA MEDIANTE CONDENSADOR-GENERADOR DE VAPOR REVERSIBLE

The invention relates to a system for the storage of heat energy in plants that produce steam, generally at high or very high pressure, based on the condensation of the steam at high pressure and high temperature. According to the invention, the secondary is a fluid medium selected from molten salt, thermal oil or another liquid having stable properties under these conditions and, during such an operation, the fluid medium passes from the low-temperature tank to the high-temperature tank, such that practically all of the condensation heat is extracted by said medium, which heat is recovered, although at a somewhat lower temperature, when the exchanger operates as a steam generator. The aforementioned exchanger has frustoconical vertical tubes in order to improve the performance thereof.
