Working Principle of Shell and Tube Heat Exchanger:

working principle of typical shell and tube heat exchanger

The work inside a shell and tube heat exchanger is fairly simple. There are two fluids, of different starting temperatures, flow through the heat exchanger.

One fluid flows through the tubes and the other flows outside the tubes but inside the shell. During this process, heat is transferred from one fluid to the other through the tube walls. The fluid inside the tubes is either heating or cooling by the other fluid outside the tubes.

The fluids on the shell or the tube side can be either liquids or gases. In order to transfer heat efficiently, a larger heat transfer area is required which can be realized by using many tubes. In this way, waste heat can be put into use wisely leading to efficient energy conservation.

As shown in the figure above, it’s the basic working process of Filson shell and tube heat exchanger.

Shell and Tube Heat Exchangers: The Ultimate FAQ Guide

What are Shell and Tube Heat Exchangers?

Like a Heat Exchanger, Shell and Tube Heat Exchangers are equipment that helps facilitate the transfer of energy from a functioning fluid to the next whether as liquids, gases, or solids.

In essence, this device places two functioning fluids in thermal closeness via tubes encased in shell cylindrical in shape.

What are the Components of a Shell and Tube Heat Exchanger?

For efficient operation, this device must have a number of components.

Without these parts, the device may fail or perfume poorly.

Here are the parts of this equipment:

 Shell and tube heat exchanger

Shell and tube heat exchanger

Shell and tube heat exchanger system

Shell and tube heat exchanger system

· Shell

This part is the first thing you notice when you come across a Shell and Tube Heat Exchanger.

Outer shell is characterized as the casing of this device housing all the parts of a Shell and Tube Heat Exchanger.

It also holds the process fluid.

· Ports

Ports are connections that avail hook ups for the process mediums.

The ports could be NPT type connections or face flanges.

Tube side fluid in

Tube side fluid out

Shell side fluid in

Shell side fluid out

· Enhanced Surface Tubes

There are several tubes encased in the device, and they come in a bundle.

Tubes transport the fluid from the entry to the exit via the fluid flow process on the tube-side.

Tube is often removable for service and maintenance purposes.

Tubes must be resilient to large temperature differentials/fluctuations, have excellent thermal transfer properties, and resistant to corrosion.

When selecting a Shell and Tube Heat Exchanger, tube material is a key consideration.

Some of the tube materials include brass, copper, and different steel alloys.

These materials are suitable for tubes because of their exposure to stress that occurs due to being subject to the temperature differential.

· Plain Tubes Single/Two-phase Heat Exchangers

An exchanger with a single-phase lets the phase of the fluid remain constant all through the whole process.

What happens is that a liquid enters the device leaves the device as a liquid.

An exchanger of two-phases typically causes a stage-change when the transfer of heat occurs.

What happens in this case is that heat enters the device and leaves as a liquid.

· Baffles

Baffles are barriers located within the shells.

Baffles optimize the general volume of thermal mixing that takes place in the coolant pipes and the fluids in the shell-side of the device.

They create turbulence within the encasing (shell) to reduce concentrations and improve the efficiency of cold or hot.

While baffles are simple design concentrations, they are key to proper function.

· Turbulator

A turbulator is an insert which forces a turbulent flow via the tubes and prevents fouling or sediment processing.

Turbulator also increases the capacity of the exchanger’s heat transfer.

· Outlet/Inlet Plenums

They are found on the end of the device.

It is the open area where the tube bundle discharges or collects the cooling fluid.

How do Shell and Tube Heat Exchangers Work?

This device works on the idea that a hot fluid passing over/around a colder fluid transfers its energy in the cold flow direction.

A Shell and Tube Heat Exchanger has two inlets and outlets each positioned strategically on opposite sides.

Every fluid enters the device through the respective inlets and exists via a respective outlet.

The tube-flow goes through the tube bundle and exits through the tube outlet.

Tube-bundle is secured by tube plates or metal plates referred to as tube sheets.

Similarly, on the second part of the device (shell-side), fluid passes through the case’s inlet to the tubes and then leaves through the outlet of the device.

Further, the headers positioned on the two opposite sides of the tube bundle develops storage areas for the flow on the tube-side.

It is often divided into parts depending on the particular type of heat exchanger.

A turbulator positioned in the tubes causes a turbulent flow of fluids.

Also, baffles in the shell help maximize the volume of thermal mixing that occurs in between the shell-side fluid and coolant pipes.

The shell-side fluid moves via the baffles causing the fluid movement to repeatedly go past the tube bundle.

In the end, the fluid transfers energy and then exits the device at a lower temperature.

Fluids can pass through the device once or several times via a single-phase exchanger or two-phase exchanger respectively.

What is the Application of Shell and Tube Heat Exchangers?

This machine is used in many industries and comfort applications for cooling and heating fluids.

They have several applications due to their compatibility with both gas and liquid.

The applications are:

  • Condensers
  • Coolers
  • Process heaters
  • Reboilers used for
What are the Designs of Shell and Tube Heat Exchangers?

There could be design subtleties for specialization in the application, however, this device contains some consistent features which are responsible for its design.

There is a pressure differential so that if there is an unexpected leak, the cross-contamination problem is limited.

Normally, the pressure would be greater in the tube shell, hence, if an unexpected leak occurs the process fluid flows into the cooling medium.

Such a design prevents the process fluid from being contaminated.

Shell and Tube Heat Exchanger has these additional features:

  • Baffles
  • Inlet/Outlet Plenums
  • Four Ports
  • Tubes/tube material
  • Shell; it is the outer portion of the device holding the process fluid and housing the internals.

Even so, there are two main ways of design for this equipment.

They are mechanical and thermal design.

Thermal design is done using computer programs from Heat Transfer Research Incorporated and Heat transfer and Fluid Flow Service.

There is a focus on calculations such as pressure drops, heat transfer coefficients, sides fluids are allocated and tube size among others.

The mechanical design of the device provides information on issues such as flange thickness and shell thickness.

These aspects are calculated with the use of a pressure vessel code. However, ASME is the popular code for this machine.

What are the Available types of Shell and Tube Heat Exchangers?

There are basic types of this equipment and their regulation is by (TEMA) Tubular Exchangers Manufacturers Association.

According to TEMA, there are three types of equipment that are built uniquely to serve special purposes.

The designs are focus on aspects such as the shell, the back header and the front-end header.

These parts are then labeled using letters for easy identification.

  • U-Tube

 Shell and tube heat exchanger system

Shell and tube heat exchanger system

For this device, the main component, tube bundle, consists of several tubes that easily bend directly into a U-shape.

One tubeplate connects the tubes and the shell.

The cooling fluid option moves through the U-tubes from the upper half of the header and leaves via the lower half of the header. As such, it creates a multi-pass design.

It has a bend that enables increase in size due to heat to occur without applying expansion joints.

The reason for this is because bend-side of the equipment is free-floating in the shell and it lacks space for expansion/contraction.

It is imperative to understand that cleaning the bend sides of this device is difficult.

Nevertheless, it is suitable when using high-temperature differences in places expansion is anticipated.

· Fixed Tube Sheet

Shell and tube heat exchanger unit

Shell and tube heat exchanger unit

This device applies two stationery tube sheets often welded on the shell.

Fixed tube sheet exchanger is easy to manufacture as well as the most cost-effective.

The expansion should be prevented in this device as tubes are tightly attached to the casing through the tube sheets.

Operators may suffer damage or expansion if the temperature difference is high.

That is, especially between the shell and tube-side flows, hence, temperature-difference has to be kept very small.

Besides, the outside of the tubes is not accessible for cleaning.

In the event that you foul the exterior of the tubes using the cooling fluid on the shell-side, the efficiency of the shell and tube heat exchanger will reduce.

· Floating Head Heat Exchangers.

This device combines the best of the other above two devices.

While one side of the device is free to expand using a floating tube sheet, the other end is attached still to the housing using a fixed tube sheet.

Due to the tube sheet, the tubes can increase in size with enhanced temperatures.

This process occurs simply and it does not disform the pipes.

Those operating this device creates a difference in high-temperature without being fearful of destroying the equipment.

It is also easy to clean the insides of the tube.

This type of Heat Exchanger is the best type for use in different processes.

Its only downside is the high cost; however, it has excellent maintenance and efficiency.

When considering purchasing a shell and tube heat exchanger, a Floating head heat exchanger is the most preferable choice.
