RE: Flare and Degassing Stacks

[Subject Prev][Subject Next][Thread Prev][Thread Next]
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?

Regards, Harold Sprague
