Coal Mills are used to pulverize and dry to coal before it is blown into the power plant furnace.. Operation. 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.

The hot gases are usually heated by the exhaust gas of the furnace, or, are the exhaust gas from the furnace; this increases the overall plant efficiency due to recapturing of heat from the exhaust gas system. Coal Inlet coal is fed to the centre of the grinding table. Coal fed to the mill may be raw or pretreated.

How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

Most coalfired capacity (88%) was built between 1950 and 1990, and the capacityweighted average age of operating coal facilities is 39 years. About half of the coal capacity operating in 2016 use bituminous coal as their main energy source, a type of coal that comes from Appalachian states such as West Virginia, Kentucky, and Pennsylvania.

Some plants have operated safely with and without these systems. Coal characteristics profoundly influence risk. Lower rank coals are generally more easily ignited inside the coal mill. High volatile matter and highly reactive coals encourage preignition inside the mill. Higher moisture content requires temperature extremes inside the mill.
