Abstract
The rotor of a rotary regenerative air preheater is constructed for the loading of the heat exchange basket modules into the sectors of the rotor in a radial direction through the periphery of the rotor. The heat exchange basket modules are arranged in a plurality of axially spaced layers with the lower baskets supporting the baskets located above. To provide the support and to facilitate the loading of the baskets, each basket includes an integral grating structure at the top surface thereof which extends partially above the uppermost surface of the basket frame. This provides a clear sliding surface as well as a support for the baskets in the layer above. The invention eliminates the support gratings which are a part of the rotor structure, except at the bottom of the rotor.
