Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal. It is a form of fugitive dust. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle. However, coal dust
Most of the world's coal production of over 5 billion short tons a year is used to help generate nearly 14 trillion kWhr of electricity, with especially significant use in the United States, China, Japan, Russia, Canada, and Germany. Coal generates about 56% of the world's electrical power.
used coal for heating, and later for cooking. Burning coal was easier because coal burned longer than wood and, therefore, did not have to be collected as often.
