“…(1), where kaolinite reacts with alkali chlorides forming alkali-alumonisilicates and HCl. Similar reactions between different vaporized alkali species and aluminosilicates have been observed in a number of studies dealing with co-combustion of coal and high-alkali fuels [65][66][67][68] as well as fundamental investigations on different aluminosilicates-sorbents for capturing alkali vapors [51][52][53][69][70][71][72]. According to Fig.…”

“…In this study, kaolin and alumina were used as additives. Kaolin, which consists mainly of kaolinite (Al 2 Si 2 O 5 (OH) 4 ), has been recognized as considerable additive for agglomeration prevention [2,10,14,15]. van der Drift et al [16] had assessed kaolin for preventing ash agglomeration.…”

“…The reaction between vaporised halides and kaolin has previously been characterised by means of water digestion [49,51,53,54]. The chemical reaction products are water insoluble whereas the unreacted halides are water soluble [49].…”

“…The chemical reaction products are water insoluble whereas the unreacted halides are water soluble [49]. The fly ash samples in this work were fractioned chemically in a similar way as were the fuels based on the leaching test developed for biomass fuels [55][56][57] which has also been applied for fly ashes [54].…”
