The invention comprises a coal-fired burner system for use in a drum mix asphalt plant or drum dryer used for producing asphalt paving composition. Coal to fire the burner is ground to a -200 mesh size by an air-swept rotary impact mill, and a classifier at the exit from the mill controls the size of the particles leaving the mill. The pulverized coal particles are recovered from the …
2. The system fan must supply enough suction to pull the materials from the collection point(s) all the way through the ductwork to the baghouse and then through the filters and out to exhaust. 3. To do that it must overcome the resistance to flow created by the filters and the ductwork. 4. Conversely, static pressure or static resistance

PA fans give positive pressure upstream of the coal pulverizer and handle relatively clean air. In power plants, PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area. These fans produce pressure upstream of the pulverizer, to push the coal and air mixture through the pulverizer into the furnace.
Coal Shop Safety. General Safety Rules Oxygen Concentration Coal grinding should be done in inert atmosphere Basic rules for the Oxygen during coal grinding are: < 14% O2 for Petcoke and Anthracite < 10% O2 for coal with volatiles below 30% < 9% O2 for coal with volatile above 30% The interlocked maxmax is 1 % point higher.
