Abstract:
1. A regenerative air preheater, comprising: a housing defining a first conduit and a second conduit, each of the first and second conduits configured to receive airflow therethrough; a heat exchanging body disposed within the housing, the heat exchanging body configured to rotate in a first direction relative to the housing so that portions of the heat exchanging body are alternatingly exposed to the first conduit and second conduit; at least one seal extending between the heat exchanging body and the housing, the seal comprising a mounting section removably coupleable to the heat exchanging body and a sealing section configured to contact the housing as the heat exchanging body rotates to inhibit leakage of air between the first and second conduits, the seal comprising a resilient member with a bellowed contour; and a support member coupled to the seal, the support member configured to inhibit the overflexing of the seal in order to thereby inhibit damage to the seal, the support member comprising a contact portion extending in a direction generally perpendicular to the mounting section of the seal and configured to contact a bellow of the resilient member to exert a force on the resilient member so as to substantially absorb a rotational stress on the seal.
