Title:
HEAT TRANSFER ELEMENT FOR A ROTARY REGENERATIVE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2011/022131
Kind Code:
A2
Abstract:
A rotary regenerative heat exchanger [1] employs heat transfer elements [100] shaped to include notches [150], which provide spacing between adjacent elements [100], and undulations (corrugations) [165,185] in the sections between the notches 150. The elements [100] described herein include undulations [165,185] that differ in height and/or width. These impart turbulence in the air or flue gas flowing between the elements [100] to improve heat transfer.
