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.
