Problems affecting performance in Shell and tube heat exchangers The main problems affecting the performance are usually due to one of the following: + Fouling + Tube vibrations + Leakage + Dead Zones
What is Heat Transfer? Heat is transferred from one object to another in three possible ways, Conduction, Convection and Radiation.
Difference between Shell passes and Tube passes In shell and tube heat exchangers the number of shell passes or the number of tube passes will always come across. The number of passes in general affects your pressure drops in shell and tube heat exchangers. This short article will show the […]
