Abstract

In this cooler grate according to the invention the supporting surfaces of the grate plates fixed on grate plate supports are provided with cooling gas openings which open upwards and are constructed in the form of substantially endless annular gaps, so that on the one hand a particularly effective cooling of the grate plates and on the other hand a particularly intensive cooling of the material transported over the cooler grate is achieved.
