In the pulverized coal combustion system, coal ground to a very fine size (70–80% passing through a 200-mesh screen or 75 μm) is blown into a furnace. Approximately about 10% of the total air required for combustion is used to transport the coal. How is the fuel selected in the pulverized fuel system Mcq?
