Sugar Powder Explodes...how?
Discussion
Just read a news story on my cell phone about an explosion in a sugar factory that caused a death to one person and severe body burns to another. Supposedly powders such as sugar and other particles can ignite. How is this possible? Should we all be careful when openinga fun dip or nestles chocolate mix?

the finely granulated powders burn very easy, they don't need much heat to ignite, and they then burn, and pass heat on the the next particle,
i guess you never did that custard powder experiment at school?
Alluminium will burn quite easy too in powder form
Not aware of such an experiment. Seems so strange to me though. Lets use to propel cars LOLi guess you never did that custard powder experiment at school?

Flour mills, coal mines, anywhere that has the potential of large clouds of fine dust are at risk of explosion.
It's the cloud effect that does it, nice mix of very fine particles and oxygen.
Custard powder is the best readily available 'source'. The trick is in releasing the powder to get a good cloud and delaying the small initial charge. Apparently.......

Ah, the joys of having someone stand on the roof of a 10 storey building with a tin of milk powder and someone at the bottom with a flame.
With some skill, you can get a nine storey column of flame running up the side of the building.

Particles have to be airborne, i.e. being pumped or blown. Spark can be created by static electicity from particles rubbing together.
There was a theory at one time that the real damage to the Titanic was caused by coal dust in the bunkers (on beams and ledges etc.) being dislodged by the collision and forming a dusty atmosphere which then exploded.

didnt someone try and run a car on coal dust way back in the old days, or did i invent / imagine thisThere was a theory at one time that the real damage to the Titanic was caused by coal dust in the bunkers (on beams and ledges etc.) being dislodged by the collision and forming a dusty atmosphere which then exploded.

OT - wasn't that theory the one considered for the Lutsitania, not the Titanic?There was a theory at one time that the real damage to the Titanic was caused by coal dust in the bunkers (on beams and ledges etc.) being dislodged by the collision and forming a dusty atmosphere which then exploded.
