摘要

The method of manufacturing a rotor for a vertical shaft air preheater that rotates about a vertical axis between streams of hot gas and cool air. The rotor comprises a series of independent compartments that each contain a mass of heat absorbent element. The rotor is constructed by simultaneously securing to a rotor post two similar sector shaped compartments disposed at 180 DEG to each other about the rotor post and by continuing to attach additional pairs of similar sector shaped compartments to opposite sides of thr rotor post until the compartments define a rotor. During construction there is at all times a substantially balanced assembly. The compartments are pivotally attached to the rotor post and joined together at their outer extremeties to form a composite assembly that extends around the rotor post.
