Abstract
The invention relates to a grate for incineration plants for the incineration of combustible material, in particular refuse, comprising at least one grate track, which is composed of fixed and movable grate-lining rows, which are arranged alternately in the direction of flow of the combustible material and have a number of grate-lining units lying side by side, the grate-lining units being connected in the region of their rear end to fixed and movable grate-lining carriers respectively and moving with their front end on or over the following grate-lining unit, and a drive being assigned to the movable grate-lining units, which drive has a torsion bar led out of the underblast region. The grate is distinguished by the fact that the movable grate-lining carriers are firmly connected via a torsion lever to the torsion bar and thus have a common pivoting point with the associated torsion bar, and that the grate-lining units are designed in a circular segment shape in such a way that the non-linear movement, resulting from the drive mechanism, of the movable grate-lining units is compensated for.
