Why is flour so flammable?

Flour grains are so tiny that they burn instantly.
When one grain burns, it lights other grains near it, and the flame front can flash through a dust cloud with explosive force..
Why does salt put out a grease fire?
Salt, on the other hand, apparently is a great absorber of heat for its volume. It sucks so much heat out of the grease that it simply can’t support combustion anymore. Bottom line: Never, ever use a pressurized fire extinguisher on a grease fire. Baking soda is probably not going to do the trick.
