A shell and tube heat exchanger is a class of heat exchanger designs. 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 inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed of several types of tubes: plain, longitudinally finned

Function of Heat Exchangers
This arrangement is what we mean by a heat exchanger: the gas jets cool down and the water heats up. A heat exchanger is a device that allows heat from a fluid (a liquid or a gas) to pass to a second fluid (another liquid or gas) without the two fluids having to mix together or come into direct contact.
Shell and tube heat exchanger Advantages
This can also be a disadvantage as at lower heat duty, there are more compact heat exchangers such as plate type exchanger. Maintenance – cleaning of tubes is difficult and fouling is always an issue when overall heat transfer coefficient is addressed. This requires periodic cleaning of the shell as well as the tubes
