ABSTRACT:
A sealing device for a rotary regenerative heat exchanger has a rotary regenerator whose one end slidably contacts with the rotary regenerator, a slide member, and a seal plate urged to the other side of the slide member by pressure difference across the plate. The seal plate is mounted on the housing, while a supporting member is secured with the slide member to contact with intermediate portion of the seal plate. When the slide member is worn, the supporting member is separated from the seal plate to decrease effective rigidity of the seal plate to maintain contact of the seal plate with the slide member.
