The features of the pulverizer
Modern pulverizer systems for boilers are direct-fired systems and consist of the following major features:
1. A raw coal feeder that regulates the coal flow from the coal bunker to the pulverizer
2. A heat source that preheats the primary air for coal drying, either the boiler air heater or a steam-coil air heater
3. A primary air fan that typically is located ahead of the pulverizer (pressurized mill) or after the pulverizer (suction mill)
4 .A pulverizer
5. Piping that directs the coal and primary air from the pulverizer to the burners
6. Burners that mix the coal and combustion air, both primary and secondary
