These systems are indirect-fired, where coal is crushed in mills/pulverizers, then classified by size for collection as a fuel or dust through a heated air conveyance network. This network generally includes a mill, classifier, cyclone, pulverized fuel bin, surge bin, dust collector and interconnecting ductwork

temperature, combustion in a cyclone furnace is more appropriate. Here the coal is crushed and injected into swirling air in a cyclone. The liquefied ash collects on the walls of the cyclone and is drained away. For small steam-generating units, stokers provide a slower, more stable combustion process. Lumps of coal are spread on a grate
