The input and boundary condition data are determined based on data collected when operating 600 MWe and for calculating coal particle size distribution using Rosin-Rammler law. The simulation is carried out by varying the three sizes of fineness, namely those that pass the 200 mesh sieve with 70%, 60% and 50%.

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. 1 a and b)) can be used. Horizontal air ...
