Firetube Heat Flux Calculations
Firetube Heat Flux Calculations
(OP)
I have what seems to be a simple question, but I cannot seem to verify.
I am trying to calculate the fire tube heat flux in accordance with API 12L. My question is:
1.) When calculating the flux area on a "U-type" fire tube, can you account for the entire length of tube on both passes?
For example if I have a U-type fire tube that has a total length of 20 ft (10 ft one way and 10 ft back), can I use the entire 20 ft for the area calculation?
Thank you in advance.

Thanks,

So it ends up being what is your effective heat transfer area: Is it really 10 feet of tubing times two or does that 20 feet also include the U-bend area?
