Abstract

An air-cooled grate block of a grate for the thermal treatment of waste, in which the grate blocks are arranged so as to rest one on top of the other in a step-like manner. The block body designed as a cast part has a top wall, forming a bearing surface, and a front wall, on which a foot is integrally formed. A first cooling passage section runs from a wall inlet, arranged on the underside of the top wall, through the top wall and the front wall to an outlet opening arranged in the front wall. A cooling passage wall which starts from an inlet opening arranged adjacent to the foot and to the front wall and is at a distance from the front wall and the top wall forms a second cooling passage section fluidically connected to the first cooling passage section at the wall inlet. A grate which consists of the abovementioned grate blocks is likewise described.
