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 baskets are removed from the rotor with a removal lug or tool which includes a lever portion and a hook portion with a beveled edge. The beveled edge and then the entire hook portion are inserted under the outer edge of a basket and then rotated with the lever portion whereby the hook portion engages the basket. The lug or tool is then pulled outwardly to remove the basket.
