Descripition:
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 pressuere 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, etc. So, it is also called Tubular Heat Exchanger.
Shell and tube heat exchanger design:
Counter current heat exchangers are most efficient because they allow the highest log mean temperature difference between the hot and cold streams. Many companies however do not use single pass heat exchangers because they can break easily in addition to being more expensive to build. Often multiple heat exchangers can be used to simulate the counter current flow of a single large exchanger.| The Heat Exchanger Tube Specifications Φ20 | |||||||||
