Th e 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 fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.
