Reduced wear and self cleaning stoker seal

摘要

A sealing apparatus (22) for use with a traveling grate (18) including a base (44) and one or more legs (42) extending upwardly from the base (44). The sealing apparatus (22) includes at least one flange (52) extending outwardly from one or more of the legs (42). The flange (52) includes a surface (53) extending between the leg (52) and one or more edges (52A, 52B, 52L) of the flange (52). The surface (53) includes a sealing portion (55) adjacent to the leg (52) and one or more discharge portions (56) sloped downwardly from the sealing portion (55) to one or more of the edges (52A, 52B, 52L), for discharge of wear materials therefrom. The sealing portion (55) is positioned proximate to a portion of the traveling grate (18) and defines a gap (G2) therebetween. The gap (G2) is configured to mitigate flow therethrough.

1. A sealing apparatus for use with a traveling grate comprising:
a base; at least one leg extending upwardly from said base; at least one flange extending outwardly from said at least one leg, with the at least one flange defining a surface extending between said at least one leg and at least one edge of said at least one flange, said surface comprising: a sealing portion adjacent to said at least one leg, and at least one self-cleaning discharge portion sloped downwardly from said sealing portion to said at least one edge, for discharge of wear materials therefrom, and said sealing portion stationarily positioned proximate to a portion of the traveling grate and defining a first gap therebetween, said first gap configured for stationary positioning of said sealing portion to mitigate flow therethrough, wherein said portion of the traveling grate travels over said stationary sealing portion.
