Numerical and experimental analysis of pulverized coal

In pulverized coal-fired (PCF) power plants (PPs), coal is pulverized in a mill, and it is then transferred to the burners and furnace volume for combustion. Depending on the physical and chemical properties of the coal, different types of pulverizing systems (e.g., vertical and horizontal air-swept (Fig. 1a and b)) can be used.
