ABSTRACT:
Method and apparatus for treating, in particular cooling, bulk material which is lying on a conveying grate (10) in the form of a layer (20). The gas is passed through the grate (10) and the layer (20) from the bottom upward. The grate is moved forward and back in its entirety, with the layer of material (20) being held in place during the return stroke. The stroke frequency is selected to be sufficiently low for there to be substantially no vertical mixing of the layer of material (20). A blocking plate (30) or the like is provided for the purpose of holding the layer (20) in place. The avoidance of the vertical relative movement within the layer of material (20) improves the heat recovery.
