ALL YOU NEED TO KNOW ABOUT SHELL AND TUBE HEAT EXCHANGER

A shell and tube heat exchanger is used in high-pressure applications where the temperature of the fluid is regulated using a shell and tube system through which the fluid flows. Exchangers are used for both heating and cooling processes, but largely they are used for cooling processes. They are mostly used in oil refineries and chemical industries. 

From the name, one can understand that these exchangers are used for transferring heat from one fluid to another. These exchangers consist of a shell that is a large pressure vessel with a bundle of tubes present inside it. One fluid runs through the tube and the other fluid runs through the shell and during this process the heat flows from hotter fluid to cooler fluid due to which the temperature of the hotter fluid comes down. 

A Shell and tube heat exchanger is necessary for cooling certain fluids in the industries to avoid accidents due to overheating. In many industries, fluid can only be heated up to a certain degree for a certain function after which the temperature must be controlled to ensure a controlled and effective production process. Heat exchangers are required to keep water, gas, oil and chemicals within a safe temperature range. Heat exchangers can also be used to detain steam or heat exhaust that is released as a by-product and use further in the manufacturing process. This increases the efficiency of operation and cost-effectiveness as a whole.

There are different parts associated with a shell and tube heat exchanger such as heat transfer tubes, heat exchanger fans, condensers, belts, coolants, tubes and lines. All these systems present inside the shell and tube heat exchanger increase the functional efficiency of the heat exchanger and improves the flow of the fluid inside it.
