Shell Tube Heat Exchangers have a wide range of applications in oil refineries, as well as other chemical processes. They aid in high-pressure applications.
They are made up of a large pressure vessel called the shell which has many tubes inside it. This is the reason it is known as “shell tube heat exchanger”. The set of tubes is called a tube bundle comprising various types of tubes like plain, longitudinally finned, et al.
Transfer of heat between two fluid happens through the two fluids, one of which flows through the tubes and another one through the shell. Tube walls facilitate the heat transfer either from the shell side to the tube or vice versa. The fluids can either be gases or liquids.
We, at Shyam Heat Exchanger, manufacture and supply heat exchangers with a large heat transfer that facilitates maximum amount of heat exchanger. Our heat exchangers carry many tubes to increase the heat exchange. Waste heat is also efficiently utilized conserving energy.
Types of shell tube heat exchangers
There are two kinds of heat exchangers. The first kind uses one phase on each side; either liquid or gas. These are known as single-phase or one phase heat exchangers.
The other kind of heat exchangers is the two-phase heat exchangers.
- Evaporator: These types of shell tube heat exchangers are used to heat a liquid and boil it into a vapor (gas)
- Condenser: These types of shell tube heat exchangers are used to cool gas (vapor) to condense into a liquid.
- Inter-cooler and after-cooler heat exchanger: These are used to transfer heat from machinery to other. They comprise of a tube and fin radiator.
Many people consider the shell tube heat exchanger as the best. They cool hydraulic fluid, as well as oil, in engines. They also cool or heat the water in swimming pools. The common applications of these heat exchangers include:
- Oil refineries
- Food and beverages industry
- Hydropower and thermal power
- Sugar industries
- Pharmaceutical industries
- Cement industries
- Hydraulic and pneumatic industries
- Induction and furnaces
- Glass industries
Advantages of shell tube heat exchangers
- Pressure drop across the tube cooler is a little less
- They are great for the systems that demand high operating pressure and temperature
- It is easy to locate and plug the tube leaks as a pressure test can be easily carried out
