Abstract

The heat exchange baskets for a rotary regenerative air preheater are loaded radially into the rotor rather than axially from the duct end. The rotor is divided into sectors by diaphragms, and support gratings are provided in each rotor sector with the baskets being positioned and supported on the gratings. The angle of each rotor sector is smaller than the complimentary angle of each basket such that the outboard end of each basket can contact the diaphragms before the contact of the inboard end. The baskets thereby serve to stiffen the rotor structure while reducing bypass gaps.
