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

Herein is an example of one way to do it:

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

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?
