Abstract
A grate block for a combustion grate including a block body having an upper wall which forms a bearing surface and along which the combustible material is to be conveyed and a front wall which has a lower bearing edge, the bearing edge being designed to come into contact with the bearing surface of an adjacent grate block in a feed direction, wherein the upper wall has an air supply opening formed by an air supply channel. The air supply opening is at least partially surrounded by a thickened portion which protrudes from the bearing surface, forms a protective channel extending the air supply channel, and is designed to prevent liquid from flowing into the air supply opening. A molded part for fastening to an upper wall of a block body of the grate block.
Claims6
A molded part for fastening to an upper wall of a block body of a grate block about an air supply opening which is configured in the upper wall and formed by an air supply duct extending through the upper wall,
- wherein the grate block is specified for a combustion grate and the block body is configured as a casting, wherein the upper wall forms a bearing face along which the incinerator charge is to be conveyed,
- wherein the molded part, in the fastened state, forms a thickening that projects from the bearing face, surrounds the air supply opening, forms a protection duct, which extends the length of the air supply duct, and is specified for preventing liquid flowing into the air supply opening, and
- wherein the protection duct is enclosed by an inner flank of the thickening and the thickening has an outer flank that adjoins the inner flank and runs in a descending manner on the side that faces away from the protection duct.
