An analysis was conducted on the relationship between the calorific value of different types of coal and the theoretical air requirement. It was found that the theoretical air volume required for generating the same amount of heat during combustion is the same for different types of coal. The concept of the air/coal ratio was improved by proposing the concept of the air/carbon ratio, which ...

Mining coal. Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earth's surface, but others are deep 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.

Abstract. Continuous variations in coal quality have a strong influence on operation of thermal power plants. However, in absence of realtime measurements of quality, the operators remain partially blind to the actual coal being consumed, leading to suboptimal operation. A twostage solution is proposed for realtime soft sensing of coal type.
