ABSTRACT:
A heat transfer element for a rotary regenerative preheater has first and second heat transfer plates. The first heat transfer plate defines a plurality of generally equidistantly laterally spaced apart parallel straight notches. Each notch has adjacent double ridges extending transversely from opposite sides of the first heat transfer plate. Undulations extend between the notches. The second heat transfer plate is adjacent the first heat transfer plate and defines a plurality of generally equidistantly laterally spaced apart parallel straight flat sections. Undulations extend between the flat sections and the flat sections are spaced apart a distance generally equal to the lateral spacing of the notches. The notches of the first heat transfer plate are in contact with the flat sections of the second heat transfer plate to define channels therebetween.
