ROTOR POST WITH FLOATING TENSILE HEADER

摘要

A rotary regenerative air preheater (10) having a rotor (14) mounted to a central rotor post (16) for rotation within a surrounding housing. Upper and lower rotor post headers (44, 46) provide means for mounting diaphragms (40). The upper rotor post header (60) includes an interior opening (62) for receiving the rotor (14) and an outer peripheral portion (66) having a plurality of circumferentially spaced slots (64). The upper portion (78) of the inboard end (80) of each diaphragm (76) defines a box-shaped lug (82) which is received in one of the slots (64) to prevent radial movement of the diaphragm (76).
