摘要： 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.

摘要： A fiber optic sensing system comprises a housing disposed in a flow path, and a fiber optic sensor. The fiber optic sensor comprises an optical fiber secured in the housing, a Bragg grating, a light source for transmitting light to the optical fiber, and a detector for detecting light filtered by the Bragg grating of the optical fiber and monitoring wavelength changes of the detected light. The fiber is substantially perpendicular to the flow path. The housing defines an opening at an upstream side to allow flow through the flow path to exert a pressure on the optical fiber and cause a deformation of the Bragg grating.
