Nov 17, 2012Specifically, 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 than 70% mean higher carbon

Less than Optimum coal fineness, fuel balance or pulverizer airflow increases Fuel NOx. Prompt NOx. Typically insignificant; producing 5% of the total NOx formed during coal combustion. Prompt NOx is only significant in very fuel rich flames which are inherently low producers of NOx due to reduction in thermal and fuel NOx.

Various ways of expressing fineness have been used and two remain in common use millesimal fineness expressed in units of parts per 1,000 and karats used only for gold. Karats measure the parts per 24, so that 18 karat = 18⁄24 = 75% and 24 karat gold is considered 100% gold.

Coal pulverizers. Coal pulverizers are essentially volumetric devices, because the density of coal is fairly constant, are rated in mass units of tons/hr. A pulverizer accepts a volume of material to be pulverized which is dependent on the physical dimensions of the mill and the ability of coal to pass through the coal pulverizing system.
