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.
A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions. The classification function plays the important role of ensuring that only fine particles are sent to the boiler.
