LOL.... Ah, how naive we are (no offense).
It's not a matter of showing something as simple as "no ignition source." That's easy.
You have to get explosive certification. You have to sit down before a formal review board and explain how there's no way that the wires could be damaged and lead to arcing in "other" areas of the system. In short, you're probably talking about spending $30k just to prove your point. I'm not talking hardward; those are just the labor costs of the meetings and such you're gonna be sitting in on.
Oh, and certified explosion proof motors are EXPENSIVE right off the bat. Are they any different? Probably not, but the certification process ain't cheap on the vendor's end either.
That's a real possibility! I'll have to think on that some.Another possiblity would be an air driven fan system. A lot more complex that electric fans but zero chance of sparking in the chamber.
Any idea how long it would take for fuel to diffuse the length of the chamber? My WAG is that it'll take a lot more than an hour, indeed it might take weeks.
Pure diffusion? No idea. But realistically convection currents and such would be doing more work than diffusion.
For what it's worth, right now I'm thinking of a two point eductor system in the U. One pointing down each leg of the chamber with the inlet to both being at the "center" of the system.
I do like the air motor idea though. I'll definately have to give that some thought!
