  • Fly ash

    Fly ash material solidifies while suspended in the exhaust gases and is collected by electrostatic precipitators or filter bags. Since the particles solidify rapidly while suspended in the exhaust gases, fly ash particles are generally spherical in shape and range in size from µm to 300 µm. The major consequence of the rapid cooling is that few minerals have time to crystallize, and .
