Heat exchanger | Uses, advantages and applications
What is a tubular heat exchanger?
A heat exchanger is a process equipment designed to transfer heat between two fluids (liquid, vapor, gas) or between the surface of a solid and a moving fluid.
The manufacture of the heat exchanger can be performed in different grades of stainless steel or special alloys and can withstand high and low operating pressures and a wide range of process temperatures. In the manufacture of heat exchangers, welding is a key aspect of the process. The tubular heat exchangers are very efficient process equipment and high speeds improves heat transfer considerably.
Sizing of a tubular heat exchanger
To carry out the sizing of a heat exchanger, it is necessary to have certain starting data, such as the process flow, the initial and final temperature, as well as the physical properties of the product.
An essential factor for the calculation and sizing of a tubular heat exchanger is to be able to characterize the behavior of the product in a reliable and precise way, through laboratory tests, where the main properties of the product can be determined, such as:
Â· Specific heat.
Â· Thermal conductivity.
