Coal power plant - SlideShare

Crushing the coal into a fine powder makes easirer to burn it more completely. Coal mills grind the larger of 2 inch pieces to face powder and mixed them with primary combustion air which transports the coal to the furnace and preheats the coal to drive off excess moisture content. By pulverizing the coal combustion efficiency of coal increases.

1.7 Lignite Combustion

Pulverized coal-fired units fire much or all of the lignite in suspension. Cyclone furnaces collect much of the ash as molten slag in the furnace itself. Stokers (other than spreader) retain a large fraction of the ash in the fuel bed and bottom ash. Spreader stokers fire about 15 percent of the coal in suspension and the remainder in a bed.
