Separation of unburned carbon from coal fly ash: A review
Jul 15, 2019 In general, coal ash can be divided into three components: slag, bottom ash, and fly ash. The majority of coal ash produced in modern utility boilers is fly ash [].The principle components of fly ash are unburned carbon and spherical ash components, including glass cenospheres, magnetic particles, and fine Si Al ash [11,76], as shown in Fig. 1.The reasonable application of coal fly ash is of
