The real cause of black smoke?

WTC fires, thick black smoke. Claimed by troofers to indicate low temperature and lack of oxygen.

Buncefield Oil Terminal Fire, December 11, 2005. Thick black smoke, obviously abunduant oxygen supply.


But the WTC office fires weren't fueled by crude oil you say?

Guess again, whack-jobs.


Not quite a Gravy quality debunking, but it works.

Burning plastic wire insulation

The black smoke being "oxygen starved" is one of the silliest of the 9/11 claims.

Not to mention all the carpet padding, foam seat cushions, and the carpeting itself, which these days is largely made from recycled plastic. All of it is ultimately derived from oil.

Not to mention it's not even really BLACK. It's more a shade of gray.

I'm afraid these morons have seen steam from stacks in industrial cities and mistaken the white steam for smoke.

Generally, smoke from a normal fire (house on fire, car on fire, bon-fire, office building on fire) is some shade of gray to an almost black. I don't recall ever seeing snow-white smoke from any fire I've started, er, uh, seen.

Ever seen smoke from a car fire at a distance? O2 starved? I think not.

That New Scientist article linked in the OP is quite interesting.

Has anyone heard more about the "Hawk 10" microwave transmogrifyer? In specific, how much power does it require to convert plastics back into crude? If its requirements are low enough, then this could be a significant technical achievement.

See, there's hope. Need to see some proof, though...

The real cause of black smoke? The College of Cardinals couldn't get a majority for the new Pope.

Black smoke generally indicates free burning fire. Gray/white smoke indicates
fire has been "knocked down" and is being extinguished .

From NIST NCSTAR 1-5A, page 81, we read that there was a period when the WTC fires were "effectively damped down by OXYGEN DEPLETION"

However, I note that POLYURETHANE was used around the window casings of the towers and eventually it ignited..... Now that stuff burns with a smoky black flame giving off lots of CO and HCN.

Polyurethane foam was also used as padding for office partitions and furniture in the towers.

Then, of course, there was the PVC in the flooring tiles, electrical insulation, window blinds. PVC also burns with a smoky flame giving off HCl and benzene.

Excess unburned hydrocarbons.

Black smoke tends to come from fuel rich fires while white is from fuel starved fires.

At least that's what I vaguely remember them telling me in the firefighting classes in the Navy.

I wonder if any of the truthers even know what the fire triangle is.
