Processes
16.11.2022High-alumina coal fly ash (HAFA), which contains more than 40–50% Al 2 O 3 and more than 35–45% SiO 2, is regarded as an important substitute. Silicon-aluminum glass, mullite, and corundum phases are mainly contained in HAFA [ 3, 4, 5 ]. About 30 million tons HAFA are discharged annually and are a cause of serious pollution [ 6, 7, 8, 9 ].

Clean Coal Technologies
Clean coal technologies generally are classified by the stage of energy production at which they are applied. In precombustion technologies, sulfur and other impurities are removed from the fuel before it is burned. Combustion technologies employ techniques to prevent pollutant emissions in the boiler while the coal burns. With postcombustion technologies, fuel gas released from a
