| description abstract | OBJECT AND SCOPE This Code appIies to the pulverizing system as a whole, including all the component parts necessary to take the raw coal, hot air and tempering air at the system inlet, and deliver pulverized coal in proper mixture with air and/or flue gas at the desired temperature at the outlet of the system. This Code applies to the most commonly used systems. The direct-fired system in which pulverizers deliver the coal directly to the burner. This system usually comprises the following equipment: Pulverizer and classifier Feeder Exhauster or pulverizer fan Air inlet and tempering air connection, including control damper Discharge coal and air piping, including valves Motors and/or steam drives Sources of hot air or flue gas Figures 1 and 2 iIlustrate the arrangement of these components in pressure and suction systems for direct firing. The storage system in which the coal is pulverized and stored in bins from which it is fed to the burners as needed. This system usually comprises the following equipment: Pulverizer and classifier Feeders, raw coal and pulverized coal Exhauster or pulverizer fan Pulverizer and hot flue gas fan Coal and air piping including hot air inlet damper, cold air damper, and vent damper Motors and/or steam drives Source of hot air or flue gas Vent cleaning equipment, which may be vent cyclone, concentrators or filters Cyclone, cyclone air lock Vent fan Figure 3 illustrates the arrangement of these components for a typical storage system. | |
