Why Pulverized Coal is Used in a Power Plant

Why Pulverized Coal is Used in a Power Plant

 · In plants that burn pulverized coal, silos feed coal to pulverizers (coal mills) that take the larger 5 cm pieces, grind them to the consistency of talcum powder, sort them, and mix them with primary combustion air, which transports the coal to the boiler furnace and preheats the coal in order to drive off excess moisture content.
