How to determine the number of Shell Passes in Shell and Tube Heat Exchangers
This short articles describes how to find how many shells needed in series that would be sufficient to perform the duty required.
Classification of heat exchangers according to construction
What is a heat exchanger? A device to exchange the thermal energy between two or more fluids at different temperatures. In simple terms; if you want to use a hot fluid to heat up a colder one you can use a heat exchanger to do the job. Heat exchangers are […]
What is Shell and Tube Heat Exchanger
Shell and Tube heat exchanger uses Shell and Tube Heat Exchangers are the most commonly used in the chemical processing industries today. It possesses large surface areas for heat transfer and is capable of operating at high temperatures and pressures. Shell and tube heat exchangers are frequently selected for applications […]
What is a Plate heat exchanger
What is a Plate Heat Exchanger? Plate heat exchangers are essentially a number of pressed metal plates, aligned on a frame clamped together with gaskets between the plates. Each pressed plate is corrugated, having a number of alternating ridges and grooves. The pattern and geometry of the corrugations are a […]
What is a Double pipe heat exchanger
Quick description What is a double pipe heat exchanger? Double pipe heat exchanger is perhaps the simplest of all heat exchanger types. Double pipe heat exchangers are also known as hairpin, jacketed pipe, jacketed U-tube and concentric pipe. These styles of double pipe may have a bundle of inner tubes rather […]
Recommended Shell and Tube side velocities
Recommended shell and tube side velocities values are listed below, the values can be used for preliminary design purpose when designing shell and tube heat exchangers, these are guidelines that are in place as lower velocities can cause fouling issues and very high velocities can cause erosion issues. If there […]
