A heat exchanger, for heating or cooling bulk solids, includes a housing including an inlet for receiving the bulk solids, an outlet for discharging the bulk solids, and a heat exchange chamber disposed between the inlet and the outlet. The heat exchanger also includes spaced apart heat transfer tubes supported within the housing, between the inlet and the outlet, and extending through the heat exchange chamber, for indirect heat exchange of a heat exchange medium in the heat exchange chamber with the bulk solids that flow, by gravity, from the inlet, and through the heat transfer tubes, toward the outlet. The heat transfer tubes include a first end for receiving the bulk solids, and a second end for release of bulk solids. At least one of the first end and the second end is moveable relative to the housing to accommodate thermal expansion or contraction.
