Radiation detector for parabolic-channel power plant, has receiver pipe comprising heat storage element for buffering temperature fluctuations of heat transfer fluid, where storage element is designed as cable that comprises core

摘要

The detector has a receiver pipe (10) through which heat transfer fluid i.e. oil, flows. The receiver pipe has a heat storage element (14) for buffering temperature fluctuations of the heat transfer fluid. The storage element is designed as a cable that comprises a core (16), where the core is made from zinc-aluminum-alloy. The core is enclosed by a corrosion protection layer (18) that is made from ceramics i.e. magnesium oxide. The protection layer is arranged in an inner side of a steel casing (20), where the storage element is arranged in an inner area (12) of the detector.
