What is the difference between splash baffles and downcomer anti- jump baffles?
Splash baffles are used in low liquid rate service. Their function is to prevent liquid from being “blown” over the overflow weir. Anti-jump baffles are used to prevent liquid from blowing to the opposite flow path on multi-pass trays. Splash baffles are located just slightly in (towards the active area of the tray) from the overflow weir. They are commonly used in conjunction with notched overflow weirs. Their height must exceed the spray height for full effectiveness. The Koch-Glitsch Ballast® tray design manual has excellent illustrations of these features.
