What is a Shell and Tube Heat Exchanger?

A shell and tube heat exchanger consists of many tubes mounted inside a cylindrical shell. The figure shows a typical tube heat exchanger that might be used in a petrochemical plant. Two fluids will exchange heat, one fluid flows outside the tubes, while the second fluid flows inside the tubes. Fluids can be single or two phase and flow in parallel or cross/counterflow arrangement.

The shell and tube heat exchanger consists of four main parts:

Front Channel (head or collector): This is where the fluid enters the tube side of the heat exchanger.

Back Channel, (head or collector): This is where the tube-side fluid leaves the exchanger or returns to the front channel in exchangers with more than one passage on the tube side.

Tube bundle — this consists of tubes, tubesheets, baffles, and tie rods to hold the bundle together.

Shell: contains the tube bundle. The other fluid enters the body part, if there is a baffle, it moves between the baffles and leaves the shell.

Fixed Tubehseet Tube Heat Exchanger BEM, AEM, NEN

 

 

Fixed Tubehseet Shell and Tube Heat Exchanger Advantages

It provides maximum heat transfer area for a given shell and tube diameter.

Provides single and multiple tube passages to ensure optimal flow rate.

Less costly than removable tube bundle designs.

Fixed Tubehseet Shell and Tube Heat Exchanger Disadvantages

The casing side/outside of the tubes is not accessible for mechanical cleaning.

There is no design to allow differential thermal expansion between the tube and shell side. This expansion can be solved with a suitable compensator placed on the body side.

 

Floating Tubesheet Shell and Tube Heat Exchanger, AEW, BEW, BEP, AEP, AES, BES

 

 

Floating Tubesheet Shell and Tube Heat Exchanger Advantages

The floating Tubesheet design enables differential thermal expansion between the shell and the tube bundle.

Both the tube bundle and the casing side can be inspected and mechanically cleaned.

Floating Tubesheet Shell and Tube Heat Exchanger Disadvantages

To mount the floating Tubesheet cover, it is necessary to bolt it to the Tubesheet. The bolt circle requires the use of space where a large number of tubes can be placed.

Tubes cannot expand independently, so applications of large thermal shock should be avoided.

 

U-Tube type  Shell and Heat Exchanger BEU, AEU

 

 

U-Tube  Heat Exchanger Advantages

U-Tube design allows differential thermal expansion between shell and tube bundle

At the same time, each tube can expand independently of the other tube.

Both the tube bundle and the shell side can be inspected and mechanically cleaned.

They are more cost-effective than the floating head design.

 

U-Tube Heat Exchanger Disadvantages

Some tubes may be skipped in the center of the pipe bundle due to U-bend.

Due to the U-bend, the tubes can only be cleaned by chemical methods.

Due to the intertwined assembly of bent tubes, individual tubes are difficult to replace.

Single tube pass or true countercurrent flow is not possible.

The tube wall thickness in the U-bend is thinner than in the straight section of tubes.

When the head is in a vertical position with the side facing up, it is difficult to drain the remaining fluid inside the piping circuit.
