ANALYSIS OF THE CONDITION OF COAL GRINDING

ANALYSIS OF THE CONDITION OF COAL GRINDING

B. Miller, in Ultra-Supercritical Coal Power Plants, 2013 Grindability. Pulverizer systems, which integrate drying, grinding, classification, and transport of the ground fuel to the burners, can present the greatest problems when switching coals/fuels (Carpenter, 1998).Low quality fuels may have grinding properties that are markedly different from the pulverizer design coal (Kitto and Stultz ...

In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.
