Abstract
The invention relates to a cooler grate for a reciprocating grate cooler, with a plurality of grate plate supports extending transversely with respect to the cooler grate and constructed as hollow bodies, on which in each case grate plates are supported so that they are co-ordinated in transverse rows and sealed by means of screw connections, wherein the grate plates have cooling gas openings and cooling gas connecting channels are constructed between the grate plate support and the cooling gas openings. Reliable sealing as well as quick installation of the grate plates is achieved in that each grate plate, so as to form a cooling gas connecting channel, has a hollow box-shaped lower part with a base wall which is in gas-tight form-locking engagement with the front long wall of the grate plate support, and that on the underside of each grate plate at least one tightening bolt engages, the said bolt passing through the rear long wall of the grate plate support towards the exterior and being clamped there by a bolt nut.
