Te process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a f ne powder. 2. Te coal powder mixes with hot air, which helps the coal burn more efciently, and the mixture moves to the furnace. 3.
Once miners fracture a coal seam, they load the fractured coal onto conveyor belts and trucks for hauling. The mining operation sends coal collected from a seam to treatment plants near the mine site. This process removes all unwanted material, such as dirt or sulfur, from the coal before its use in power plants and other coal-based …
