Abstract
The modular heat exchange baskets for a rotary regenerative air preheater which normally have a single stacked array of heat exchange plates, are constructed with heat exchange plate support bars intermediate the top and bottom surface. The basket then has two separate stacked arrays of heat exchange plates which permits the plate material or arrangement in the top of each basket to be different from the plate material or arrangement in the bottom. For side loaded air preheaters with basket support gratings, the arrangement of heat exchange plates can be changed without the need to move the gratings.
