as on-site fuel. Coal has a wide range of moisture (2-40%), sulfur (0.2-8%), and ash content (5-40%). These can affect the value of the coal as a fuel and cause environmental problems in its use. The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat coal deposits are mined

For the mill equipped with spring load system, the grinding force is overloaded at reduced mill load. This will result in additional wear on roller and table segments and will produce excessive mill vibration. While at high mill load operation, the grinding force is insufficient to meet the requirement for mill load increase. o 180 160 140 120 100

The operations of a mill need to be controlled to respond effectively to changes in plant load and coal quality. Combustion optimization relies heavily on optimization of the mill output. Frequently start-ups and shut-downs of mills bring the impact on power plant to achieve both low NOx and CO2 emissions.

of coal-fired plants (Mills, 2011). In the absence of sufficient large-scale electricity storage capability, the effect has been to force coal (and gas) fired units in some countries to deliver greatly varying output to enable thegrid system to meet load at all times. The challenges presented by this situation will only
