A heat transfer element basket assembly for a rotary regenerative heat exchanger having a basket framework including oppositely disposed first and second side shells, means for holding the side shells in a spaced relationship, and heat absorbent material is disposed within the framework. The inboard end portions of first and second substantially planar flange plates are mounted to the outboard end portions of the first and second side shells, respectively. The outboard end portions of the first and second flange plates are each mounted to an adjacent diaphragm plate to install the basket assembly in the heat exchanger rotor. The first and second side shells of the basket assemblies define an angle therebetween which is substantially equal to the angle of the diaphragm plates. The outboard end portions of the first and second flange plates may be mounted to a diaphragm plate by bolting, welding or a combination where one of the flange plates is bolted and the other flange plate is welded.

Basket design and means of attachment for horizontal air preheaters

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.
