How many baffles are typically present in a 3-pass horizontal shell and tube condenser?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

In a 3-pass horizontal shell and tube condenser, the typical configuration includes two baffles. Baffles serve several essential purposes in shell and tube heat exchangers, such as directing the flow of the cooling medium, enhancing heat transfer efficiency, and providing structural support to the tubes. In a 3-pass design, the fluid flows through the tubes three times, and the arrangement of two baffles creates a defined flow path that maximizes the surface area for heat exchange while also ensuring a smooth flow through the condenser. This setup reduces the risk of stagnation and improves the overall thermal performance. Having more or fewer baffles would not facilitate the intended flow distribution or could lead to inadequate heat transfer, which is why two is the standard number for this specific design.
