heat exchanger performance
(OP)
how do you rate a heat exchanger's performance? what parameters should one know aside from the inlet and outlet temperatures and pressures?
thanks.
thanks.

Then you can calculate the duty and see if it is performing according to the duty that it was designed for.

You should be able to get started with suggestions that rmw and itdepends provided. If you are still struggling, suggest listing what data are available.

i would appreciate it much if you guys can help me sort this out. thanks.

Perhaps this may help....
Almost all heat exchangers are designed to a performance point that is optimum for the thermal cycle that they are in.
Generally speaking, process heat exchangers are designed for optimum generation of product at minimum capital expense. Power plant heat exchangers are selected to generate maximum elctric power based on the thermal cycle which will generate the maximum return on investment for the owner.
That being said, it is important to underatnd that most heat exchangers do not operate exactly on the "optimum design point" because systems are rearely operating exactly on that point.
This makes the testing and rating of the individual heat exchangers difficult, because there always must be an adjustment between the thermal performance observed and that which formed the basis of design....
My opinion only....

Or, you can roughly measure CW rate (using portable ultrasonic meter) and follow the similar steps to measure the exchanger performance.

We wound up running Ridlime through the exchanger to restore performance to the unit. It had been pretty badly fouled by the cooling water side.
Here's a link to the Cv calcualtions:
