Abstract
A rotary regenerative heat exchanger 10 having a rotor 12 mounted to a central rotor post 18 for rotation within a surrounding housing 20 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 50 including a flexible sealing strip 72 is mounted to the hot end edge of each radially extending partition 16 of the rotor 12 to establish a seal across the gap between the radially extending partitions 16 and the confronting face of the sector plate 24 of the housing 20 as the rotor is rotated. Each radial seal assembly 50 is provided with a back support leaf 64 having an outward portion 68 which provides a backstop to limit the backward bending of the flexible sealing strip 72 so as to preclude stressing of the sealing strip beyond its yield point.
