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.

A flexible radial bi-directional seal for an air preheater comprising:
- a first base plate;
- a second base joined to said first base plate;
- each plate having a planar section and an oppositely curved flange;
- and
- a plurality of flexible spaced apart leaves mounted at least partially in between said first and second base plates.
A flexible radial bi-directional seal for an air preheater having a sector plate comprising;
- a base plate assembly including first and second base plates each having a planar section and a curved flange, said planar sections of said base plates joined together;
- and
- a replaceable pack assembly removably attachable to said base plate assembly and disposed at least partially in between said first and second base plates, said replaceable pack assembly having a plurality of flexible spaced apart leaves for sealingly engaging the sector plate.
A flexible radial bi-directional seal for sealing a diaphragm against a sector plate in a rotating drum-type air-preheater, comprising:
- a base plate assembly including a pair of rigid base plates, each base plate of said pair having a planar section and a flange, said planar sections of said base plates joined together, said flanges of said pair of base plates generally curving away from each other and forming a longitudinal slot therebetween;
- a replaceable pack assembly comprising a pack of parallel planar leaves separated by spacers, said leaves fastened together along engagement edges, said replaceable pack removably attached to said base plate assembly with said engagement edges of said replaceable pack engaging into said longitudinal slot, said replaceable pack secured into said longitudinal slot with removable fasteners passing through said base plate assembly and said replaceable pack.
