Yes I am. The client had their junior engineers draw it up for fabrication. I pointed out that it MIGHT be a good idea if they would check the shell thickness as well. Silence.Bill,
I am not aware of any significant thrust loads from the startup or operation of a gas flare. The operational pressures are low. The thrust from ignition is minimal. A petrochemical blast from a vapor cloud in the general area could create some unintended loads. A deflagration load can approach about 4 psi.
I presume you are designing to STS 1?
"Um, well, they're mechanical engineers."
"Well, mechanical engineers typically design equipment structures."
"Our guys don't even know what that is."
*SIGH*
"All right, but you'll have to pay me for it."
"No problem! Thanks!"
I had never even seen STS-1 - I thought that was the name of the first Space Shuttle mission. Anyway, I located a copy online - 2006, not 2010 or 11 or whatever. Close enough.
Wind loads are the only biggie, and I've got that covered by ASCE 7-10. STS-1 has wind load criteria but it looks like ASCE 7-95 or -98 or so.
I'm finished with the degas stack, a 45-footer. Now I hear the flare stack may be between 200 and 300 feet. They claim it's to be free-standing.
At V = 150 mph? I don't think so.
