Abstract

Described is a grating plate for a sliding grating for a burned-material cooling unit, the grating plate having, in the surface which holds the materials, a recess (13) in which cooling-air outlets (10) are located and, below the recess, a cooling-air feed space (17). The depth of the recess (13) increases from back to front. The cross-section of the cooling-air feed space (17) decreases correspondingly from back to front in accordance with the change in the cooling-air flow through the space.
