Coal occurs in a wide range of forms and qualities. There are two broad categories: (a) hard coal, which includes coking coal (used to produce steel) and other bituminous and anthracite coals used for steam and power generation; and (b) brown coal (sub-bituminous and lignite), which is used mostly as on-site fuel. Coal has a wide range of

Abstract The more fluctuating renewable energy sources like solar and wind are integrated into the electric grid, the more it is desirable that conventional power plants actively contribute to compensating the fluctuations. For coal fired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand. Model predictive control is a possible way to ...

Safe mill operation requires, in addition to maintaining the appropriate coal/air ratio, that the temperature of the fuel stream exiting the roller mill be maintained within safe limits. This requisite temperature control is accomplished by mixing cold air with the "hot" or primary air delivered to the mill.

An area of power plant control that has received much less attention from mod elling and control specialists is the coal mills. This is in spite of the fact that it is now accepted that coal mills and their poor dynamic response are major factors in the slow load take-up rate and they are also a regular cause of plant shut-down (Maffezzoni, 1986).

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.
