Water-cooled grate block for an incinerator

A cooled grate block as part of a grate for an installation for thermally processing waste, wherein the grate blocks are arranged in a step-like manner one above the other and configured in such a manner in order to rearrange and convey the combustion material during the combustion by means of pushing movements which are carried out relative to each other, comprising

• a block member which is in the form of a cast component and which has an upper wall which forms an external support face which extends at least partially parallel with a longitudinal axis of the block member for the waste which is intended to be processed,
• a planar hollow space which is arranged directly under the support face for receiving a cooling fluid and which is delimited at the upper side by the upper wall, at the front by a front wall, at the bottom by a base, at the rear by a rear wall and laterally by side walls, wherein the base is at least partially formed by a base plate,
• a fluid supply line and a fluid discharge line which are connected to the hollow space,
• at least one redirection element which is arranged in the hollow space in order to redirect a cooling fluid in the hollow space from the fluid supply line to the fluid discharge line, and
• a distributor element which is arranged in a front region of the hollow space, in order to distribute the fluid which is introduced through the fluid supply line into the hollow space.
