ABSTRACT:
A flexible radial bi-directional seal for sealing a diaphragm against a sector plate in a rotating drum-type air preheater includes a baseplate assembly having a pair of rigid baseplates. Each baseplate has a planar section and a flange, with the baseplates joined together and the flanges generally curving away from each other and forming a longitudinal slot therebetween. A replaceable pack assembly includes a pack of parallel planar leaves separated by spacers. The replaceable pack is removably attached to the baseplate assembly with engagement edges of the leaves of the replaceable pack engaging the longitudinal slot.
