Shell & tubeheatexchangers are the most versatile type of heat exchangers. They are used in many alternative energy applications including ocean, thermal and geothermal. Shell & tubeheatexchangers provide relatively large ratios of heat transfer area to volume. They can be easily cleaned.
This guide provides a detailed, step-by-step methodology for performing heatexchangerdesign calculations, starting from heat duty estimation and moving through LMTD/NTU analysis, overall heat transfer coefficient determination, sizing, and pressure drop checks.
Design of shellandtubeexchanger: A shellandtubeheatexchanger is one of the most popular exchangers due to its flexibility. In this type, there are two fluids with different temperatures; one flows through the tubes and the other flows through the shell.
Here is a step-by-step approach to specifying a new shell-and-tubeheatexchanger. We shall focus on sensible heat transfer, and make extensive use of Chapter 11 in Perry’s Handbook (3).
Shellandtubeheatexchangers are vital for effective, safe heat transfer in the process industry. Their design, versatility, and adherence to standards like TEMA and API 660 ensure their use in petroleum refineries, power plants, and chemical facilities.
A followup arti- cle on advanced topics in shell-and-tubeheatexchangerdesign, such as allocation of shellside and tubeside fluids, use of multiple shells, overdesign, and fouling, is scheduled to appear in the next issue.
This paper proposes a novel single-shell-pass shell-and-tubeheatexchangerdesign with alternative inclined baffles. The design includes paired semi-ellipse shapes with baffle cut along the vertical axis such that the segments are interlocked in a crossed pattern.
