As shown in Figure 2, coal and preheated primary air first enter the crusher section. Here the coal is im- pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4" size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the two-stage pulverizing sec- tion.
