Abstract: A brush seal is mounted between rotary and stationary components in a flow stream having solid particles. A gap is formed through the brush seal bristles and a deflector plate is disposed to catch and deflect solid particles on the upstream side of the brush seal to direct the particles through the gap to the downstream side of the brush seal. In this manner, the solid particles of the flow stream do not erode or otherwise deteriorate the brush seal bristles or ancillary parts of the brush seal. The deflector plates may be directed axially upstream, at an angle to a plane passing through the brush seal or may comprise an arcuate configuration directed upstream.
