reference books/material for designing with thermal strain
reference books/material for designing with thermal strain
(OP)
Was advised by vpl to try posting this thread here as there were no responses on the Heat Transfer & Thermodynamics engineering forum.
Can anyone recommend resources (print/online) for design of structures that will see 700°C (1300°F) temperature gradients?
The structure is a circular tray in an axial reactor/combustor. Design criteria and stress-strain calculations to avoid excessive thermal distortions are what I am looking for.
Thanks!
Kevin

RE: reference books/material for designing with thermal strain
Second, either one of the above would be a major design headache for any design outfit which has many years experience, and likely would not be correctly designed the first time by a person who is not aware of any design code.
The type of structure you defined sounds like something one would find in a gasifier or coker. I think the dozen or so companies that design such a device would have proprietary design standards which are aimed at providing a reliable device while meeting local codes, such as ASME and NFPA.
RE: reference books/material for designing with thermal strain
I definitely mean 700°C gradient and not 700°C temperature.
Clearly there are some common sense rules regarding allowing members to move with the thermal expansion, but has someone managed to convince a publisher to collect these "rules" and put them into print?
Or do these guidelines solely reside in the heads of engineers & designers at the "dozen or so companies that design such a device" that you refer to?
RE: reference books/material for designing with thermal strain
I think the latter is generally true, and forms the basis of proprietary knowledge which separates the vendors from each other, and provides a barrier for startups to overcome the status quo.
To the extent each vessel impacts worker or public safety, the different design codes are used ( ASME, NFPA)in their particular areas, but as far making the process work reliabily , or to provide a competitive design that lasts beyond a typical 6 -30 yr life cycle, then the details are generally proprietary.
