A Comparison of Three Types of Coal Pulverizers

Properly sized pulverized coal, however, passes into the fan section. In this section, an integral fan wheel, with abrasion-resistant alloy fan blades, transports the pulverized coal from the pulverizer section through the coal pipes to the burners. A typical arrangement of an ATRITA pulverizer system is shown in Figure 3.
