Fuel preparation for a pc boiler occurs in a mill, where coal is typically reduced to 70% through a 200-mesh (74-μm) screen. Figure 2 shows a particle-size distribution from a bowl-mill grinder typically used in power plants. A typical utility specification for particle size distribution of the coal is that 70% of the mass should pass through a 200-mesh screen, …
