Coal pulverisation | The Nature Of Science

Crushing the coal into fine powder makes it easier to burn it more completely (in fact, powdered coal is explosive when airborne!) This is important, because the act of burning coal requires the use of energy, so by making the coal easier to burn, less heat energy is being used to access the energy locked within the coal. It is also
