Fixed tubesheet heat exchangers are often designed with expansion joints to handle the differential thermal growth between the tubes and the shell. Learn how to use Exchanger Optimizer 3 to
• specify operating metal temperatures and evaluate the cost impact of adding a flanged and flued or bellows expansion joint
• modify designs to eliminate the need for expansion joints, resulting in more economical configurations
Temperature effectiveness is the change in process fluid stream temperature divided by the difference between the hottest and coldest temperatures in the exchanger. If the required effectiveness is greater than 0.8, non-ideal fabrication or variable process conditions can significantly reduce performance of many exchanger types (shell-and-tube, plate-frame, plate-fin, etc.). Learn about applications where high effectiveness is expected, the factors which degrade effectiveness, and what a designer can do to ensure adequate performance.
