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

Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

The mill is one of six mills supplying the 650-k (steam production of 650 t/h) boiler. However, the proposed method in this chapter is so generic that it can be applied to other types of coal mills. The coal mill is illustrated in Figure 1 . The coal is fed to the coal mill through the central inlet pipe, where it is pulverized by a series

The Chinese government has ordered the country's coal mines to "produce as much coal as possible" as it tries to increase production as winter approaches, and ease an ongoing energy crunch.

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
