ABSTRACT:
A method of constructing a rotor assembly (12) for a rotary regenerative heat exchanger wherein the rotor compartment (14) is formed of a plurality of prefabricated, shop-assembled subcompartments (20) which are shipped disassembled from the central rotor post (16) for final erection in the field. The method of the present invention maximizes shop welding in the horizontal downhand position and minimizes welding in the vertical up position both in the shop and in the field.
