Document Type and Number:
Japanese Patent JP2002532676
Kind Code:
A
Abstract:
The thermal performance of the heat transfer element assemblies for rotary regenerative air preheaters is optimized to provide a desired level of heat transfer and pressure drop with a reduced volume and weight. The heat transfer plates in the assemblies have notches for maintaining plate spacing and oblique undulations between the notches. The undulations on adjacent plates extend at opposite oblique angles. The ratio of the openings of the undulations to the openings of the notches is greater than 0.3 and less than 0.5. The pitch (spacing) of the notches is greater than two inches and the angle of the undulations with respect to the notches is greater than 20 DEG and less than 40 DEG .
