Coal Grinding Simulation

Coal is an important energy resource for meeting the further demand for electricity, as coal reserves are much more abundant than those of other fossil fuels. In pulverized coal fired power plants, it is very important to improve the technology for the control of environmental pollutants such as NOx, SOx and ash particles including unburned carbon.

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.
