A regenerative gas-gas heat exchanger having a column type of construction, and heat transferring elements which absorb heat in a hot gas flow, give off heat in a cold gas flow, and are cyclically conveyed from one of the gas flows to the other. The heat transferring elements form a fluidized bed during the operation; this fluidized bed, in relation to the gases which flow in an upward direction through the gas permeable column bottom, moves in a counter-cross flow over this column bottom. |
