Abstract

Grate bar (6) for use in a stepped grate for a waste incineration plant, said stepped grated consisting of grate blocks (1) placed in adjacent rows and in succession in the advancing direction of the waste and resting on parallel grate beams (2) in which every second row of grate blocks (1) are adapted to make a reciprocating movement while the intermediate rows of grate blocks (1) are stationary, each grate blocks, comprising: two stringers (3,4) mutually connected by two (half blocks) or four transverse steel rods (5) and each grate block (1) being filled up with loose, vertically hanging cast grate bars (6) resting on said steel rods (5), said grate bars (6) comprising indentations along their abutting sides forming openings for admitting primary air for the combustion, said primary air also providing the necessary cooling of the grate bars (6). The indentations along the abutting sides are formed as one single elongate indentation positioned centrally on at least one side of each grate bars (6). This provides a grate bar of simple construction at a reduced price.
