Abstract: A grate bar has a grate bar head, two side walls, a running surface behind the head and between the side walls and an underside disposed below the surface and between the side walls. A recess in one side wall forms an air slot between the surface and underside and is arranged only on one side wall, not in its opposite side wall. In a grate bar arrangement including multiple grate bars, each including a running surface and a grate bar head, in which an upper grate bar with grate bar head is moveably arranged relative to a lower grate bar so that the head may slide over front and rear grate bar running surface areas, the running surface has air slots in the front and rear areas and the head is displaceable relative to these slots so that the opening cross section of all slots remains constant.

Abstract: A method includes producing an arrangement of grate bars for supporting fuel that is burned in an incinerator or other furnace device. The method includes positioning a pair of grate bars in adjacent side by side relation and with the respective upper sides that are configured to support the fuel, in generally aligned relation. The method further includes after positioning the grate bars, manipulating a fastener through respective recesses that extend in the grate bars, so that the grate bars are held in operative connection and in pressed together relation by the fastener. The method further includes subsequent to the fastener manipulation step, covering the recesses with at least one cover, such that the fastener is rendered inaccessible through the upper sides of the grate bars.
