Shell&Tube Heat Exchanger

General:

A heat exchanger is a device that transfers heat from one medium to another. Heat exchangers are used in both cooling and heating processes. Heat exchangers are most commonly used in industrial facilities such as iron and steel, petroleum, petrochemical, gas, power plants, food, pharmaceuticals, leather, textiles, air conditioning, ships, and marine industries.

Shell and Tube Heat Exchangers are one of the most popular types of exchanger due to the flexibility the designer has to allow for a wide range of pressures and temperatures. There are two main categories of Shell and Tube exchanger: one is shell and tube heat exchangers that are used in the petrochemical industry and follow TEMA (Tubular Exchanger Manufacturers Association) standards; Another is those used in the heating industry, such as heat exchangers used in feedwater heating or condensers in thermal power plants.

Changes in the main components of the structure make different types of shell and tube heat exchangers. Regardless of the industry in which this heat exchanger is used, a shell and tube heat exchanger is created from the following main components.

1. Tube Bundle
This set consists of the tubes, tube sheets, baffles, and tie rods to retain the bundle together.

2. Shell
The shell contains a tube bundle; one of the working fluids flows in the shell over the tubes.

3. Front Header
The front header also called the stationary header, is where the fluid enters the tube side of the exchanger.

4. Rear Header
The rear header is where the tube side fluid leaves the heat exchanger or in heat exchangers with multiple tube side passes, where it is returned to the front header.
