Abstract

The invention relates to a grate block forming part of a grate in a waste heat-treatment plant, comprising a block body (2) embodied as a cast part provided with an upper bearing surface (8) for the waste which is to be treated. A lower retaining part (15) is detachably connected to the block body (2). By joining both parts at least one cooling element (10) having a cooling channel (11) connected to a cooling water system can be fixed in a predetermined contact position with the block body. The block body (2) does not possess any inaccessible cavities. It can be manufactured in a cost-effective manner in a very simple standard casting process and does not need to be tested for pressure and tightness which would otherwise involve considerable expenditure. Since the cooling element (10) and the block body (2) are separated from each other and can be expanded in a different manner, the danger of leaks or cracks in the cooling elements (10) - which are made of extremely diverse materials and can have practically any shape and cross-section- can be substantially eliminated. .
