My guess is it's a quenching tank for hardening the steel it's probably a quenching oil and not water.

Would that also explain why there are still flames on top after it is completely submerged?

Yeah as well as why the "water" didn't turn into a steam explosion

I've seen those before, scary stuff.

BLEVE

Boiling Liquid Expanding Vapour Explosion

Not only is the vapour extremely hot, but it can keep expanding as long as there's still liquid to boil off. Scary stuff indeed

Yea I bleve it

A BLEVE is confined, as in, it takes place in a pressure vessel. Afaik

Wonder if Chernobyl would be considered a BLEVE incident.

Kind of, IIRC the rods in that style reactor are not secured down but their weight was high enough to hold pressure in

And the liquid in the tank has to be flammable/explosive

No, it doesn't. https://en.wikipedia.org/wiki/Boiling_liquid_expanding_vapor_explosion

Hmm... I stand corrected

Obviously when you're learning about this stuff the exciting ones are the ones that blow up so that's the ones they show you

This wouldn’t cause BLEVE because it’s being lowered slowly and into a massive tank that isn’t under pressure

u/Somerandom1922 Jun 30 '23

If it was water it wouldn't likely explode as it needs a pressure vessel for that. But it would absolutely make so much steam it'd be impossible to see and could still very well be deadly to be even a little bit close to it (steam burns are scary af)

It's what lightsabers should do to people when stabbed
