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.
when gas is competing against coal, the flexible operation of coal power plants can lead to increased CO 2 emissions. In those systems, an effective climate policy (e.g. carbon pricing) remains ...
