ABSTRACT:
A rotary regenerative air preheater having a rotor mounted to a central rotor post for rotation within a surrounding housing whereby heat absorbent material carried in the rotor is alternately exposed to a flow of heating gas and a gas to be heated. A radial seal assembly including a flexible sealing strip is mounted to the hot end edge of each radially extending partition of the rotor to establish a seal between the partitions and the confronting face of the sector plate of the housing as the rotor is rotated. The flexible sealing strip has a tapered configuration such that the distal edge of the sealing strip and the confronting face of the sector plate define a controlled radially extending gap when the air preheater is in a hot-operating condition. A protective tip is mounted on the distal edge of the flexible sealing strip to prevent premature failure due to edge fracturing. The rigid back support leaf biases the flexible sealing strip, pretensioning the flexible sealing strip to eliminate gapping due to gas-air pressure differentials.
