Abstract
A heat exchanger for transmitting heat between gaseous media includes at least two chambers each partially filled with a solid transmitting medium in the form of pellets, granules or sand. A cold gaseous medium is injected through a first conduit into the bottom of a first of the chambers, and a hot gaseous medium is injected through a second conduit into the bottom of a second of the chambers, both media being injected at a rate for effecting fluidized beds of the transmitting media in the chambers. The chambers intercommunicate with one another via passageways extending from the first conduit so that transmitting media is transported from the first to the second chamber and from the second to the first chamber respectively by the first and second gaseous media to thereby effect an increase in temperature of the hot gaseous medium while passing through the transmitting media.
