Реферат: A grate trough forms the lower part of a grate element which has a plurality of fixed and a plurality of movable grate block rows. The grate block rows each include a plurality of grate blocks suspended next to one another on a block holding element and connected firmly to one another. The grate trough forms a carrying element for the block holding tubes of the fixed grate block rows and support for a movable grate carriage carrying the block holding elements of the movable grate block rows. The grate trough has two side walls and also a front and a rear frontal wall, the frontal walls being arranged at right angles to the side walls. The side walls and the frontal walls are provided at their junction with projections and recesses which engage one into the other, with the result that the walls are held in an exact position. The length and width of the grate trough remain constant, even after welding, since the walls cannot be displaced relative to one another. The weld seam distortion and weld seam stress are minimized due to the offset of the weld seam lines. The mounting of the grate element becomes appreciably simpler.
