Shell and tube heat exchangers are a variety of heat exchangers that create thermal contact with a pair of working fluids through tubes. One of the fluids (water) enters the dish located at left side and flow through the tubes. The use of plate technology also alleviates a common challenge of shell and tube heat exchangers; fouling. Plugging can be intentional, where a leaking tube is plugged to minimize cross-contamination between the shell-side and tube-side fluids or it can be unintentional, due to your process solidifying inside the tubes. A shell and tube heat exchanger (STHE) is a type of heat exchanging device constructed using a large cylindrical enclosure, or shell, that has bundles of perfectly spaced tubing compacted in its interior. It is the most common type of heat exchanger in oil refineries and other large chemical processes. They heat the materials inside the tanks through the use of either hot oil or steam. 852.

A shell (a large pressure vessel) with a bundle of tubes inside it. The two fluids can exchange heat by passing through a shared wall or exchanging heat by direct contact. Shell and tube heat exchanger design is an iterative process, which goes through the following steps. The two most common kinds of heat exchanger are the shell-and-tube and plate/fin. These two integral paths are usually made of thermally conductive metals (steel, aluminum alloys, etc.) Also known as shell and tube heat exchangers, these transfer heat using liquid or steam that flows through the shell to heat or cool liquid in the tubes. The other fluid (steam) enters the shell and flows over the tubes. We achieve this by using fins where the shell side fluid flow and heat transfer properties would not usually generate a high heat transfer coefficient. Select a suitable type of shell and tube exchanger. Thanks to the high heat conductivity of the metal, heat flows from hot stream to the cold one. 2) A hot fluid enters the tubes from the top left and exits from the bottom right. Fig. Shell and Tube Heat Exchangers work by transferring heat from one fluid to another. In the past, shell-and-tube heat exchangers were the preferred choice for applications involving high pressures, temperatures, or both.
