HEAT EXCHANGERS

WebA plan for increasing heat exchanger performance for shell and tube exchangers should consider the following steps. 1) Determine that the exchanger is operating correctly as designed. Correcting flaws in construction and piping that may have a detrimental effect on heat transfer and pressure drop may be the solution. Double pipe heat exchangers are the simplest exchangers used in industries. On one hand, these heat exchangers are cheap for both design and maintenance, making them a good choice for small industries. On the other hand, their low efficiency coupled with the high space occupied in large scales, has led modern industries to use more efficient heat exchangers like shell and tube or plate.
