Dynamic Modelling and Simulation of Coal Pulverizer

The physical model of the coal pulverizer with a dynamic classifier is shown in Figure 1. Two different types of classifier– static and dynamic are found in various power plants. The static classifiers possess stationary mesh of suitably designed mesh-size to filter-out coarse/fine particles.
