This patent describes an apparatus for carrying out heat exchange between a gas and solid particulate material comprising a casing having an upper inlet for particulate material and a lower outlet for particulate material and a lower grate mounted in the casing extending from the upper inlet to the lower outlet for supporting a bed of particulate material for movement from the inlet to the outlet along the lower grate. A means defines an upper grate mounted in the casing and is spaced from the lower grate including generally vertically oriented slats, each spaced from and positioned below a preceding slat in the direction from the inlet toward the outlet for defining the top of the bed of material while permitting the bed of material to expand. The casing includes an inlet for gas on one side of the casing and an outlet for gas on the other side of the casing whereby gas flows from the inlet through the lower grate, the bed of material and through the upper grate to the outlet for gas for carrying out heat exchange between the gas and the solid particulate material. Each of the slats is perforated to permit gas and fine material to pass therethrough while retaining the bed of material on the lower grate.
