Abstract
A heat transfer sheet [] for a rotary regenerative heat exchanger is shaped to include sheet spacing features [], which provide spacing between adjacent heat transfer sheets [], and undulation surfaces [] (corrugations) in the sections between the sheet spacing features []. The undulation sections [] are constructed of regularly spaced lobes [] extending at an angle with respect to the spacing features []. The undulating sections [] impart turbulence in the air or flue gas flowing between the heat transfer sheets [] to improve heat transfer. The heat transfer sheets [] may include undulating surfaces that differ in angle of their lobes [
