The pulverized coal firing was first developed in cement industry which then migrated to power and process industries. Pulverizing coal in boiler is an important factor the overall cycle efficiency. There are many types of mills available, but proper selection will enhance the reliability in achieving a consistent boiler and cycle efficiency.
to specify the process to obtain more purified coal products compared to those attainable by the conventional coal cleaning technology. Thus, for example, the ash content of clean coal is 6 to 20% in the conventional and present coal market, while the target of (advanced) coal cleaning is to produce higher

Coal seams can be mined by surface or underground methods (Figure ), with the choice of mining method dictated by both technical and economic factors. The most important technical factors are the thickness of the coal seam, the depth of the coal seam, the .
Coal mining. The process is known as acid mine drainage. It happens when certain substances (typically iron sulfide, FeS2, or fool's gold) is oxidized after being exposed to air and water. Runoff can change the pH of nearby streams to the same level as vinegar.
from coal yard. Coal feeder control the quantity of coal from coal bunker and send it to the ball mill or roll mill for pulverization process. Where coal crushed to the fine powder and mixed with preheated air come through the air from preheater. This process use for drying the coal and sends coal powder up to the burner of furnace. ...
