Calculating the Economic Value of Improved Fired Heater Efficiency
by Jim Cahill
In an earlier post about fired heater efficiency and reliability, I had spoken with Emerson operations consultant, Chris Forland, on the opportunities for refiners to optimize this energy intensive unit.
Working with engineers in the Rosemount Analytical Gas division, Chris has developed a spreadsheet with fired heater efficiency economic calculations which allows refiners to get a rough estimate of the potential value in applying efficiency solutions like the SmartProcess Heater Optimizer.
You can enter data in the cells with blue text for each fired heater in your plant to get a quick assessment. Chris has filled in typical values from a cross section of refineries in case you don't have exact data. This will let you get a feeling for the overall improvement opportunity and if there is enough return on investment to warrant a closer look.
If you have fired heater units in your manufacturing process, give this calculator a try and let us know what you think by adding a comment or contacting us.

i got a interesting result on a theoretical run with:
0% oxygen in flue gas
650F flue gas temperature
650F air intake temperature
got a 101.58% efficiency

The question comes up from time to time about where the numbers come from that are used in the calculations. Here's a note I received back from Chris:
Below is a link to Google books. The book entitled Heat Transfer Design Methods may help.
