6 FLY ASH DAN BOTTOM ASH Fly ash dan bottom ash merupakan limbah padat yang dihasilkan dari pembakaran batubara pada pembangkit tenaga listrik. Ada tiga type pembakaran batubara pada industri listrik yaitu dry bottom boilers, wet-bottom boilers dan cyclon furnace. Apabila batubara dibakar dengan type dry bottom boiler, maka kurang lebih 80% dari abu meninggalkan pembakaran sebagai fly

Fly ash material solidifies while suspended in the exhaust gases and is collected by electrostatic precipitators or filter bags. Since the particles solidify while suspended in the exhaust gases, fly ash particles are generally spherical in shape and range in size from 0.5 µm to 100 µm. They consist mostly of silicon dioxide (SiO 2
