Pulverized-coal firing is especially suitable for very large boilers and cement kilns. A wide range of coals can be burnt, but coal preparation and gas cleaning are major cost items. 70% < 75 μm is required for bituminous coals, 80% for anthracite. Coal dried with air at 250–350°C for milling in low-, medium- or high-speed mills. Main ...

Pulverised coal firing is done by two systems: i) Unit system or Direct System. ii) Bin or Central system. Unit System: In this system, the raw coal from the coal bunker drops on to the feeder. Hot air is passed through coal in the factor to dry the coal. The coal is then transferred to the pulverising mill where it is pulverised.

This is how the central system works; the raw coal is fed in the raw coal bunker where it's then directed to the dryer by gravity. In the dryer, the coal is dried up by the hot air coming from the air preheater, bled steam or flue gasses. As long as the air has enough heat energy to dry up the coal, it can be used as a drying agent.
