Abstract
A compressed-air storage installation comprising a heat accumulator for storing heat contained in compressed air and the air is passed into subterranean caverns. The heat accumulator has partitions therein which are provided between a storage medium. The partitions form a number of air passages through which the hot compressed air entering at the central region of the heat accumulator flows in an essentially outward direction, thereby cools and flows on into the cavern. PAC BACKGROUND OF THE INVENTION The present invention relates to a new and improved construction of a compressed-air storage installation having a heat accumulator for storing heat contained in compressed air, with the compressed air being passed into subterranean caverns. It is already known to employ compressed air instead of liquids as a storage medium for storing energy. The state-of-the-art compressed-air storage installations store compressed air at times of low load and utilize it at times of peak load to generate additional peak load energy. With these known installations, in order to increase the stored energy while the air is expanding, the air is heated by combustion of liquid or gaseous fuels before ente…
