The mills are usually a constant airflow mill and have a specific output in mass of coal ground depending on coal properties like hardness, moisture, and fineness which affect the mill output. in direct tangential firing systems, the pulverized coal from the coal mills is directly taken to the furnace.
Pulverizing mills in boiler plants play a major role in preparing the coal for firing in a boiler. coal, being a heterogeneous fuel, varies in its properties; the variation depends on many factors like type of origin of coal, formation, major parameters which decide the mill capacity and performance are the hardness of the coal and the total moisture level in coal.
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.
