A shell-and-tube heat exchanger is a class of heat exchanger designs. [1] [2] It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes ...
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
A shell and tube heat exchanger Shell and tube heat exchanger. Shell and tube heat exchangers consist of a series of tubes which contain fluid that must be either heated or cooled. A second fluid runs over the tubes that are being heated or cooled so that it can either provide the heat or absorb the heat required.
Shell and tube heat exchangers consist of a tube bundle which is placed inside the larger shell. [2] Due to this design these exchanger require twice the footprint of the plate heat exchanger in order to perform maintenance. Depending on the amount of cooling needed, shell and tube heat exchangers can be built in single or double pass ...
Additional effectiveness-NTU analytical relationships have been derived for other flow arrangements, including shell-and-tube heat exchangers with multiple passes and different shell types, and plate heat exchangers. [4]
In a cross-flow, in which one system, usually the heat sink, has the same nominal temperature at all points on the heat transfer surface, a similar relation between exchanged heat and LMTD holds, but with a correction factor. A correction factor is also required for other more complex geometries, such as a shell and tube exchanger with baffles.
A surface condenser is a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations. [ 1 ] [ 2 ] [ 3 ] These condensers are heat exchangers which convert steam from its gaseous to its liquid state at a pressure below atmospheric pressure .
The Tubular Exchanger Manufacturers Association (also known as TEMA) is an association of fabricators of shell and tube type heat exchangers. [1] TEMA has established and maintains a set of construction standards for heat exchangers, known as the TEMA Standard. [ 2 ]
