chicopee: I'm also trying to calculate the approximate consumed fatigue life based on existing ramp rates.
davefitz: I'm gonna buy the new standard. One gripe with 12952 i've found is that it uses unnotched steel curves for the cyclic stresses, the 'unfired' equivalent discusses both.
I must...
Thanks to everyone for such a rapid response. I guess when I wrote this post last night it was late, and I may not have been so clear.
I am looking at the stresses induced in a (HRSG boiler) drum wall (approx 1800mm od 85mm thick) during a start up (hence transient from 20°C to 280°C in an...
Hi all,
I'm trying to model what I think should be a simple case but I just can't get this going.
I've got a steel boiler drum wall for which I know how the internal temperature tracks over time. The boiler is in start up and the temperature is heating up inside. I can assume that the...
