Abstract
A brush seal assembly for a coal pulverizer includes multiple identical assembly segments. Each assembly segment comprises an arcuate brush assembly, a pair of clamping block assemblies and a pair of mounting bolts. The brush assembly includes a brush and an adjusting segment having a pair of elliptical openings. A radially inner end of the brush contacts the pulverizer yoke and a radially outer end is connected to the adjusting segment. Each clamping block assembly includes a clamping block, having a circular opening, a threaded rod, and a pair of jam nuts, the rod extending radially from an inner end mounted to the clamping block through the first jam nut, a hole in the adjusting segment, and the second jam nut. Each mounting bolt has a threaded shaft which extends longitudinally upward from the bolt head, through the circular opening of one of the clamping blocks and one of the elliptical openings of the adjusting segment, to a distal end portion which engages an opening of the pulverizer seal housing.
