Abstract
A rotary regenerative air preheater has a heat exchange basket assembly comprising one keystone heat exchange basket disposed between two lateral heat exchange baskets in each outboard sector compartment. The baskets have a trapezoidal shape such that the parallel sides of the keystone heat exchange basket and each lateral basket define the inboard and outboard faces of each basket. Heat exchange elements are loaded into the baskets such that they extend parallel to the parallel sides of each basket. Since the baskets have a trapezoidal shape, the width of the elements in the keystone heat exchange basket and the lateral heat exchange baskets are progressively reduced from the outboard face to the inboard face.
