When coal is burned to generate electricity, generally it is ground into a fine powder, blown in the boiler, and burned as a dispersed powder. What ever doesn't burn, whooshes through, is quenched and is collected as Fly Ash. It is called Fly Ash because it flies through the boiler. The ash that stays behind is called Bottom Ash.
