Mill Steam Inerting System Review and Performance

2018-2-2  Figure 1 shows a typical mill system schematic including fuel bunker, feeder, mill, primary air system and relevant dampers. Raw coal is fed from the feeder at a controlled feed rate, to meet boiler steam demand. In the meantime, hot primary air of 300°F to 700°F, depending on coal moisture content, is introduced to the mill to dry the coal and transport it to the burners. The pulverized product from the mill is classified for specified particle size distribution requirements by an integrated or stand-alone classifier (not shown). The acceptable fine particles are delivered to the burners through coal pipes by pneumatic transportation, while coarse particles are re-circulated within the mill system
