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.
Therefore, the model can be used for several on-line applications like coal mill control, performance monitoring and maintenance services. After the modeling studies, the coal mill model was used for an advanced control application. The performance of the conventional control strategy was compared to that of nonlinear model predictive control ...
Nov 17, 2012· Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% value is exceeded. Values lower ...
