| 摘要 |
A rotary regenerative heat exchanger (1) employing heat transfer elements (100) is shaped to include notches (150), providing spacing between adjacent elements (100) and undulations (corrugations) (165, 185) in sections between the notches (150). Elements (100) include undulations (165, 185) differing in height and/or width. These differing undulations impart turbulence to air or flue gas flowing between the elements (100) for heat transfer thereto. |
