플라이애쉬(Fly-Ash) (날아다니는 재?)는 화력발전소에서 석탄원료를 사용할 때 발생하는 부산물입니다. 화력발전소 등 석탄을연료로 사용하는시설에서는 석탄을 가루로 만들어서 태우는데 석탄을 태우고 나면 이러한 성분들이 산화 실리콘(SiO2)나 산화 알루미늄(Al2O3) 성분의 미세한 먼지로 남게 됩니다.

Posted on May 24th, 2023 by showes. Fly ash and bottom ash are byproducts created during the burning of coal for energy production. Fly ash is composed of tiny particles of ash carried up the smoke stack, while bottom ash is composed of larger particles that do not become airborne. Furthermore, fly ash and bottom ash are different in terms of ...
Based on the chemical and mineralogical composition, fly ash is commonly classified as Class F or Class C [82].Class F fly ash is characterized by a total Si 2 O 3, Fe 2 O 3, and Al 2 O 3 content greater than 70% and a CaO content less than 5%; the percentage of unburned carbon is generally high at ≥6.0% and up to 12%. Class F ash is …
