ABSTRACT:
A rotary regenerative heat exchanger (2) for transferring heat from a hot fluid to a cold fluid by means of an assembly (30) of heat transfer element which is alternately contacted with the hot and cold fluid. The heat transfer element assembly (30) is comprised of a plurality heat transfer plates (32) stacked alternately in spaced relationship. The spacing between adjacent plates (32) is maintained by spacers which comprise notches in the form of bilobed folds crimped in the plates (32) at spaced intervals to prevent nesting between adjacent plates, the pitch of the sloping web portions (60) of not more than half of the bilobed folds (38B) in each plate (30) will be opposite in inclination to the pitch of the sloping web portions (60) of at least half of the bilobed folds (38A) in the plates (30).
