摘要：

Some of the steps that need to be followed to select the appropriate baffle for shell-and-tube heat exchangers are discussed. Baffles play a crucial role in regulating shellside fluid flow and improving heat transfer between shellside and tubeside process fluids. It is essential to remember that baffles are available in a range of shapes and sizes, and the most common among these is the segmental baffle. The Tubular Exchanger Manufacturers Association, Inc., (TEMA) provides design guidelines for segmental baffles. TEMA baffles can be single- or multi-segmental, or tube support plates, while tube support plates are used in the no-tubesin-window (NTIW) design to ensure that all baffles support every tube, eliminating tubes with long unsupported spans. TEMA standards also specify that the minimum spacing between segmental baffles need to be the larger of one-fifth of the shell inside diameter or 51 mm.
