Abstract
A combined labyrinth/brush seal is provided in a seal between rotating and stationary components. The seal includes a plurality of arcuate sealing segments, each having one or more labyrinth teeth extending radially toward the surface of the rotating component. As original equipment or retrofit, a brush seal is provided among the labyrinth teeth in a slot formed in the sealing face of the seal segment. In one form, backing and/or forward plates for the brush seal have a tongue extending into an axially extending groove of the seal segments to prevent relative radial movement of the brush seal and seal ring segments. The end faces of the brush seal and seal ring segments may be bored and filled with weld material to prevent relative circumferential movement. Where a single radially extending slot is provided in the sealing ring segment, the brush seal may be stitch-welded to the seal ring segment along opposite sides of the brush seal.
