A shell and tube exchanger consists of a number of tubes mounted inside a cylindrical shell. Figure 1 illustrates a typical unit that may be found in a petrochemical plant. Two fluids can exchange heat, one fluid flows over the outside of the tubes while the second fluid flows through the tubes.

The floating head type heat exchanger is a type of shell and tube heat exchanger in which the tube sheet assembly is independent and free to move within the shell or the shell cover. This exchanger is widely used for the service where the temperature is high between the shell and tube bundle that creates expansion issues.

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.

A straight tube shell and tube heat exchanger has a tube sheet and a plenum at both ends as shown in the lower two diagrams. The straight tube heat exchanger shown at the right has one tube pass and the one on the left has two tube passes. Shell and Tube Heat Exchanger Design

Following diagram is the structure of a TEMA style shell and tube heat exchanger. The diagram itself is based on the TEMA standards. This diagrams illustrates all the important parts in the construction of a shell & tube heat exchanger, as per the TEMA standards. It also gives you the exact correct nomenclature for each of those parts.

Shell and tube heat exchanger is a device where two working fluids exchange heats by thermal contact using tubes housed within a cylindrical shell. The fluid temperature inside the shell and tube are different and this temperature difference is the driving force for temperature exchange.

Example 5.2 Miniature Shell-and-Tube Heat Exchanger A miniature shell-and-tube heat exchanger is designed to cool engine oil in an engine with the engine coolant (50% ethylene glycol). The engine oil at a flow rate of 0.23 kg/s enters the exchanger at 120°C and leaves at 115°C. The 50% ethylene glycol at a rate of 0.47 kg/s enters at 90°C.

Shell and tube heat exchanger system is widely used in chemical plants because it can sustain wide range of temperature and pressure. The main purpose of a heat exchanger system is to transfer ...

Four thermocouples mounted close to the four ports of the heat exchanger and connected to a digital readout indicate T h,i,T h,o,T c,i, and T c,o. The principal geometrical characteristics of the heat exchanger are as follows: Shell diameter (outer) 3.63 in. Shell length 27-1/4 in. Tube O.D. 0.250 in. Shell volume 0.70 gal.

As previously explained, the fundamental point of shell and tube heat exchangers is to pass a hot fluid through a cold fluid without mixing them, so that only their heat is transferred. The above diagram shows two inlets and two outlets, where each fluid starts at their respective inlet and exits the device at their outlets.

The shell and tube heat exchanger shown in the diagram above is a 'single-pass' heat exchanger. Here the tube-side fluid makes one pass through the exchanger from one end to the other. Many tubes and shell exchangers, however, have the tube-side fluid travelling back and forth through the exchanger on its way from the inlet to the outlet.

To understand the shell and tube heat exchanger's design and operation, it is important to know the vocabulary and terminology used to describe them. This vocabulary is defined in terms of letters and diagrams. The first letter describes the front header type, the second letter the shell type, and the third letter the rear header type.

specified) or the required length of the heat exchanger are calculated as output. In either case, the pressure drop of each stream will also be calculated. 'Design' is the process of determining all essential constructional dimensions of an exchanger that must perform a given heat duty and respect limitations on shell-side and tube-

Diagram. The diagram shows the default drawing of the shell and tube heat exchanger, with the required connecting streams. The user may also connect a vent stream to the unit. This is optional and allows non-condensable and excess vapour (typically steam) to be removed from the unit.

shell and tube heat exchanger diagram The baffles provide the support to tubes and also deflect the fluid flow approximately normal to tubes. This increases the turbulence of shell-side fluid and improves heat transfer.

Most shell-and-tube heat exchangers have multiple "passes" to enhance the heat transfer. Here is an example of a 1-2 (1 shell pass and 2 tube passes) heat exchanger. As you can see, in a 12 heat exchanger, the tube- -side fluid flows the entire length of the shell, turns around and flows all the way back.
