Steam accumulator for storage of thermal energy of vapors working medium, buffer working medium, and for heat force plants, has storing medium receiving chamber, which is separated from working medium receiving chamber

摘要

The steam accumulator has a storing medium receiving chamber (20,106,148) for a heat storage medium (22,108,146). The storing medium receiving chamber and one of working medium receiving chamber (16,74,104,144) are separated from each other by a separation wall (24,110) or multiple separation walls. The working medium is condensed or vaporized at the separation wall or separation walls. An independent claim is also included for a method for steam storage, which involves the storage of steam working medium in the working medium receiving chamber.
