2. A heat source that preheatsthe primary air for coal drying, either the boiler air heater or asteam-coil air heater

3. A primary air fan thattypically is located ahead of the pulverizer (pressurized mill) orafter the pulverizer (suction mill)

4 . A  pulverizer

5.Piping that directs the coal and primary air from the pulverizer tothe burners

6. Burners that mix the coaland combustion air, both primary and secondary

7. Controls
