Abstract
According to the present invention, a brush seal is provided having a side plate, a back plate, and a bristle pack disposed between the side plate and the back plate. The side plate is in contact with an upstream surface of the bristle pack. The back plate is in contact with a downstream surface of the bristle pack. The back plate includes a plurality of apertures positioned to provide a gas path through the back plate for gas exiting the bristle pack. In some embodiments, the back plate further includes an exit channel disposed in the back plate surface contiguous with the bristle pack, aligned with the apertures. In some embodiments, the radial length of the side plate in contact with the bristle pack is less than the radial length of the back plate in contact with the bristle pack.
