304 SS Performance for 1400F Long Term Application
304 SS Performance for 1400F Long Term Application
(OP)
Please can any one give me some help?
I am designing a fume thermal oxidizer system. The oxidizer operating temperature is 1400F and will run 22 hours/day, 300 days/year. This system supposes to work 10 years. The discharge of this oxidizer direct connects to a shell and tube Heat eXchanger (HX). Hot and cold airflows in this HX are perpendicular, cold air is 250F.
My boss wants to use 304SS to build this HX and almost every book states that 304SS good for 1500F application. Does any body have experience to share or can provide suggestion? Thanks.

I echo metengr's hot corrosion concern. Any halogens, sulfur, salts or acids should cause you to do a little more research (High Temperature Corrosion of Engineering Alloys, G. Lai, ASM, ISBN 0-87170-411-0).
What will happen when this isn't in use? It needs to be kept hot (over 100F. Other wise you might get condensation, and spalling, and thermal fatigue, and a lot of other problems.

Corrosion never sleeps, but it can be managed.
