ABSTRACT:
A stepped grate for an incinerator plant consists of grate blocks (1) placed adjacent in rows, and placed in succession in the travelling direction of the refuse and garbage resting on parallel placed grate beams (9), where every second row of grate blocks (1) is adapted to make a reciprocating movement, whereas the intermediary rows of grate blocks are stationary. The movable and the stationary rows of grate blocks (1) are placed in staggered position in the travelling direction of the garbage at a distance corresponding to half the length of a grate block, the one type of rows being terminated with half grate blocks (8). Preferably, it is the stationary row that is terminated with half blocks (8). The displacement of the rows of grate blocks removes the danger of blocking the movable row of grate blocks caused by collision between the front edge of a grate block from the movable row and the rear edge of a grate block from the stationary row.
