The sea chest provides an intake reservoir from which piping systems draw raw water. Most sea chests are protected by removable gratings, and contain baffle plates to dampen the effects of vessel speed or sea state.
It is used in some household stoves [1] and in some industrial process vessels (tanks), such as shell and tube heat exchangers, chemical reactors, and static mixers. Baffles are an integral part of the shell and tube heat exchanger design. A baffle is designed to support tube bundles and direct the flow of fluids for maximum
It can be horizontal, vertical or round vessel. [5] A vacuum action is created to pull in the gas cut mud. When the liquid enters the tank it will flow and be distributed to a layer of internal baffle plates designed for the mud to flow in thin laminar film and is exposed to a vacuum that forces the gas to escape and break out of the mud.

Gaskets are placed around the edge of each plate in order to prevent the mixing of the two fluids. Due to the temperature and pressure constraints of the rubber used to make the gaskets plate type heat exchangers are used for low pressure, low temperature applications, under 290 psig (20 bar) and 300 degrees Fahrenheit (150 degrees Celsius).

The thinner top plate deforms, while the base plate remains plane. Double embossed pillow plate section. Furthermore, pillow plates are commonly equipped with “baffle” seam weldings, which offer a targeted flow guidance in the pillow plate channels in cases, where flow distribution or fluid velocity might be an issue.
There are many advantages to shell-and-tube technology over plates One of the big advantages of using a shell-and-tube heat exchanger is that they are often easy to service, particularly with models where a floating tube bundle is available. [7] (where the tube plates are not welded to the outer shell).
The typical spray-type deaerator is a horizontal vessel which has a preheating section and a deaeration section. The two sections are separated by a baffle. Low-pressure steam enters the vessel through a sparger in the bottom of the vessel. The boiler feedwater is sprayed into section where it is preheated by the rising steam from the sparger.
A submarine tracking another submarine can take advantage of its target's baffles to follow at a close distance without being detected. Periodically, a submarine will perform a maneuver called clearing the baffles, in which the boat will turn left or right far enough to listen with the forward array sonar for a few minutes in the area that was previously blocked by the baffles.
