Heat exchanger with reduced fouling

摘要

A heat exchanger configuration (100) in which dead zones and areas of stagnation are significantly minimized or eliminated and in which inlet (40) region tube erosion is addressed by providing a sacrificial portion of tube (160) length so as to make repair and replacement of the eroded portion of tubes (160) significantly cheaper, easier and with minimal process interruption. The exchanger (100) preferably uses the axial flow direction for the shell-side fluid to reduce tube.
