Heat exchanger cost
Heat exchanger cost
(OP)
Hi, someone could help me? I need to estimate the cost of an HRSG and i need a correlation between cost and heat exchange surface.
I know that should be something like this:
C=specific_cost*A^exp
I looked everywhere on the net but i found only contradictionary value.

Hi theborg1
Try this: http://matche.com/EquipCost/index.htm
Don't forget to update the cost on the basis of:
- reference year
- reference place (e.g. from USA to Canada)
- type of cost (e.g. FOB, etc.)

I'd do it for you if I had time, but one way will be to price several sizes with the tool that Matt17 gave you, then do an exponential or polynomial regression. I assume your material and pressure would be fixed, yes?
Good on ya,

suggestion that DRWeig gives you work fine (I suggest the exponential).
Don't forget that all the functions that you'll develop are valid within a specific limit, i.e. minimum and maximum capacity which are defined for each equipment.
