The three most common types of shell-and-tube exchangers are (1) fixed tube sheet design, (2) U-tube design, and  (3) floating-head type.    In all three types, the front-end head is stationary while the rear-end head can be either stationary or floating , depending on the thermal stresses in the shell, tube, or tube sheet, due...

 A heat exchanger consists of heat transfer elements such as a core or matrix containing the heat transfer surface, and fluid distribution elements such as headers, manifolds, tanks, inlet and outlet nozzles or pipes, or seals. Usually, there are no moving parts in a heat exchanger; however, there are exceptions, such as a rotary regenerative...

SHELL AND TUBE HEAT EXCHANGERS are the most commonly used heat exchangers in oil refineries and other large chemical processes.are used when a process requires large amounts of fluid to be heated or cooled.provide transfer of heat efficiently.use baffles on the shell-side fluid to accomplished mixing or turbulence.

A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact. In heat exchangers, there are usually no external heat and work interactions. Typical applications involve...

A regenerative heat exchanger, or regenerator, is a type of heat exchanger where heat from a hot fluid is stored in a thermal storage medium and then transferred to a cold fluid. This is achieved by having the hot and cold fluids alternately pass through the same channels, washing the same surface area. Unlike recuperative heat...
