Abstract
Known high-temperature heat storage devices for the storage of heat at a temperature above 100° C. having a container for heat-storing bulk material such as gravel/ceramic spheres have a steel wall which is constructively extremely complex to manufacture for larger heat storage devices or the storage of heat at higher temperatures. According to the invention, the side wall of the heat storage device for its part is supported by a supporting bulk material and is preferably inclined, with the result that the side wall is substantially less stressed and can be made of a non-metal material such as, for example, concrete. Such a heat storage device is simple and inexpensive to manufacture and allows long-term storage of larger amounts of heat at high temperatures.
