Fouling factor
Fouling factor
(OP)
Hi,
I am handling a fin fan cooler and 1 of the potential bidders I have states that they will not confirm fouling factor for the tube side as it is by process licensor so they say. I find this quite unusual. Can someone help me, please?

A fouling factor is a double edged sword. Yes, it does give you additional area which will compensate for the loss of heat transfer due to fouling. However, the increase in area also comes at the cost of reduced velocity (because more area = more tubes) which directionly isn't what you want to reduce fouling, depending of course on the type of fouling.

Since you have not given the details of the process, when you specify the fouling factors, have a mental note of how the FF affects the cooler design as a whole (in addition to the increased area).
1. Increases pressure drop of the process fluid
2. Will have to increase the velocity of the process fluid to compensate the increased cooler length
3. With an increased area, chances are the fan motor will fall into the higher range, thereby leading to bigger fans and higher energy consumption
4. So be judicious in selecting the value of the FF
5. Also, in view of the location of the coolers (for any airborne particles), evaluate the option of using air side fouling factors too.
Thanks
