Abstract

The rotor for a rotary regenerative air preheater is fabricated from a combination of shop assembled rotor sector modules and field assembled components so as to eliminate the double plate diaphragms of conventional modular rotors. The shop assembled modules comprise one or more sectors and the field assembled components fit between the spaced shop assembled modules spaced around the rotor hub. The support gratings between the diaphragm plates support modular heat exchange baskets which are loaded into the rotor radially from the periphery.
