Good point. There may have been none.
But that wasn’t the question - at least as I saw it.
The question was what happens to any fire when a huge volume of
highly compressed oxygen is added to a fire.
I believe it would, for all practical purposes, appear the same as an explosion.
Not wanting to make a controversy or argument. Just wanting to point out a fact.
Yes - increasing the O2 PPM or percentage of the atmosphere does indeed accelerate combustion. The reverse is also true.
The movie BACKDRAFT demonstrated the effect of suddenly introducing O2 to a hot fuel with a source of ignition.
I ‘hated’ that movie for one reason — They portrayed Fire Fighters as stupid - going into an active, enclosed fire with their gear open, (not even a balaclava or face shield) without a buddy, and no respirator/ rebreather etc etc.
Otherwise entertaining.
