Exhaust Stack Design

Exhaust Stack Design

Exhaust Stack Design

(OP)
I am designing an exhaust stack for a diesel engine/generator.  The stack is 55' tall, and has exhaust temperatures around 650 degrees.  I am doing the structural design.  The SMACNA GSSC Design Guide limits the design to 300 degrees.  Is 650 degrees a problem?  How do I account for the temperature?  Will the base plate move to the point that I shouldn't anchor it with any welded connections?

Just thinking out-loud...are there any other good design references for self-supporting/free-standing stack design?

Thanks,

StructTaco

BTW - double posting is frowned upon

But 650F seems a bit high and I would expect premature stack problems.

RE: Exhaust Stack Design

ASME has a stack standard- Steel Stacks STS-1 - 2011.  It's been ages since I looked at it, and I don't remember the exact scope covered.

RE: Exhaust Stack Design

Why not a supported stack within your stack?  Check out Selkirk-Metalbestos.   We did a number of stacks for them years ago.  I below they are in Idaho.l

Thanks everyone for the helpful posts.

MikeTheEngineer:  I apologize for double posting, I wanted to reach the structural engineers in this forum for the structural aspects/views, and the mechanical engineers in the ventilation forum for the heat/temperature aspects/view.  Can I expect all mechanicals to see the structural forums, or vice versa?
