Dear sirs,
We have to design an air preheater which heats 9800 scfm ambient air using saturated steam having 2.5 ata pressure. We have come across two different procedures for designing. One is from GPSA Engineering databook section 10 and another is from Process Heat Transfer Kern chapter 16 (similar to example16.5).
the heated air goes to a combustion chamber where furnace oil is being combusted. The air is supplied by a blower.
Which method should be adapted for this?Is there any different method/ standards for this design?
Is it necessary to follow API 661 Air Cooled Heat Exchangers for General refinery Service?
1 ton/hr of steam is available.
Thanks
