Energy Savings by Use of Disk/Donut Baffling in Tubular Heat Exchangers

Abstract

The use of segmental baffling in shell-and-tube heat exchangers has become standard design practice, and process heat transfer specialists recognize that such baffling is the basis for most design procedures. Data from earlier work at The University of Texas indicate that disk/donut baffling can provide equivalent heat transfer rates at significantly reduced pressure drops. In this paper estimates are made of the potential for energy savings by this change of baffle arrangement, and, methods are provided for executing designs that involve disk/donut features.
