A B S T R A C T O F T H E D I S C L O S U R E A heat exchanger for heat exchange between downwardly flowing solid particulate material and a gas comprises a substantially conical casing having arranged at the bottom thereof a tubular outlet for material having undergone heat exchange. A tube extends downwardly into the casing substan- tially symmetrically about the vertical axis thereof and forms an outer defining wall of an annular inlet through which ma- terial to be treated is charged to the interior of the casing. Extending through the tube co-axially therewith is a gas in- let means comprising a gas inlet pipe which extends down into the casing and which forms an inner defining wall of said annular material inlet. The gas inlet pipe has a dis- charge orifice located at a given distance beneath the dis- charge orifice of the material inlet, and a collecting chamber for gas having undergone heat exchange and arranged at the top of the casing is laterally defined by the wall of said tube and the wall of said casing, and is provided with gas outlet means.
