The concept of burning coal that has been pulverized into a fine powder stems from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas. . As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel.
