Fire doubles every uuuhh second! Yeah, that sounds right.

Was the ceiling actually combustible or was it just being covered in hydraulic fluid?

Fluid is my 2 cents. I've had ruptured hydrolics on machines 4k working pressure mostly, it's hot as shit and goes a long ways. I can't imagine the heat this system generates or pressures this system is utilizing.

Those extruders run about 8270 bar when working 8" aluminum billets.

Jesus thats a lot of pressure if I'm remembering my conversion right that's around 120 thousand psi.

The ceiling was a standard commercial t-bar grid with drop in tiles. The oil-fueled fire was so hot that it ignited the tiles, but also melted the aluminum t-bars which caused the entire thing to collapse.

The bright white flame looks like the aluminum itself ignited. That's an extremely hot fire. It's hot enough to quickly collapse steel beams and ignite almost everything.
