Abstract
A yoke air seal assembly for sealing a vertical pulverizer yoke includes a yoke seal housing ring having a plurality of circumferential segments mounted together end to end in a ring. A seal ring is mounted radially inside the housing ring. The seal ring has a radially inner face having a plurality of grooves defined therein for forming a labyrinthine air seal against a pulverizer yoke. The seal ring can be segmented into a plurality of circumferential seal ring segments. The segmented ring configuration facilitates installation and replacement of yoke seal components, increases operational lifetime thereof, and reduces down time for such installation and replacement.
