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.
