Abstract
The rotor for a rotary regenerative air preheater is fabricated from upper and lower rotor shell segments and hot-end and cold-end heat exchange baskets having closed outboard ends, the rotor shell segments and heat exchange baskets defining a first gap between the upper rotor shell segment and the hot-end heat exchange basket, a second gap between the hot-end and cold-end or intermediate heat exchange baskets, and a third gap between the cold-end heat exchange baskets and the lower rotor shell segment. A system for sealing the gaps includes first, second and third sealing members, each sealing member having first and second portions. The first sealing member is mounted to the upper rotor shell segment or the hot-end outboard heat exchange basket and engages the other of the upper rotor shell segment or the hot-end outboard heat exchange basket to seal the first gap. The second sealing member is mounted to the hot-end or the cold-end or intermediate heat exchange baskets and engages the other of the hot-end or cold end heat exchange baskets to seal the second gap. The third sealing member is mounted to the cold-end heat exchange basket and engages the other of the lower rotor shell segment to seal the third gap.
