ABSTRACT:
A rotary regenerative air preheater including a housing surrounding a rotor of heat absorbent material that is adapted to rotate between a duct for heating fluid and a spaced duct that carries a fluid to be heated. Sealing means intermediate the rotor and the rotor housing include a torsion spring activated by the moving rotor that is adapted to bias the sealing means axially to provide a barrier that precludes fluid flow between the rotor and the rotor housing.
