Air classification is a mechanical separation process that uses air as the dispersion agent for particulate materials, separating them into two or more size classes by a combination of mechanical forces such as centrifugal, drag, gravity, or collision. ... For example, coarse fly ash obtained from an air classifier, as shown in Fig. 10.8, can ...

5.2.5 Classification of Fly Ash. 1. Classification by chemical components. Fly ash has the main components of SiO 2, Al 2 O 3, and Fe 2 O 3, and its composition varies due to factors such as coal source, combustion methods, and the type of furnace. The fly ash classification criteria of Taiwan, USA, and Japan are shown in Table 5.6 .

Coal ash includes a number of by-products produced from burning coal, including: Fly ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler. Bottom ash, a coarse angular ash particle that is too large to be carried up into the smokestacks so it forms in the bottom of the coal furnace.
