Coal is the primary source used for generating power, and its use continues to grow outside the U.S. Accurately monitoring combustion air and stack exhaust increases efficiency and . For energy production, coal pulverizers or mills are used to grind coal into a fine black powder so that the furnace can more easily burn it.
Process. Coal is transported to the coal bin by use of a conveyer from the coal stock piles or rail-car unloading stations. From the coal bin, the coal is fed into the coal pulverizer and dried using ~300° F air . When coal is pulverized, the process grinds the coal into a fine dust which expands the coal's surface area allowing the.
