Abstract: 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.

Abstract: The invention refers to a method for fixing a heat resistant component on a surface of a heat exposed component, by brazing of at least a part of a surface of the heat resistant component limited by a peripheral boundary edge on the surface of the heat exposed component using a molten solder. A first alternative includes: metallizing the surface of the heat resistant component at least with the exception of an edge area comprising the peripheral boundary edge; and brazing said metallized surface to the surface of the heat exposed component, wherein at least the surface of the heat resistant component consists of a ceramic material which has a physico-chemical property concerning wettability such that the ceramic material is not wettable by the molten solder, and/or a metal or a metal alloy is used for metallizing which has a physico-chemical property concerning wettability such that the metallizing is wettable by the molten solder.
