Coal mill pulverizer in thermal power plants

4.1.Drying The coal that is passing through a pulverizer is entrained by the use of hot air usually from the air heater. During the pulverization process the surface area of the coal particles increases dramatically exposing fresh coal to the entrainment air. The inherent and surface moisture of the coal is reduced by the exposure to hot air.

Fossil Energy Study Guide: 300 million years ago

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.
