Abstract
A rotary regenerative air preheater has heat exchange baskets which contain the mass of heat absorbent material commonly comprised of stacked plate-like elements. The heat exchange basket comprises a frame which is open on each end and which is closed on the sides by basket cover assemblies. Each basket cover assembly includes a light gauge membrane which is welded to the interior surface of the basket cover. Shrinkage of the membrane due to the weld imposes a pre-tension on the membrane which resists deformation of the cover assembly by the heat exchange elements.
