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, but I thought I should research the temperature implications. 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

However, for an engine exhaust you should be providing an expansion joint at the exhaust connection.
Try Selkirk IPS for example.

fegenbush: I downloaded the ASME document you mentioned, this has been very helpful, thanks. It addresses all the applicable design aspects that I need (structural, including temperature and linings/coatings and single vs. double wall), plus a lot more things for the plume/ventilation/exhaust/mechanical experts.
