Coal and coal ash characteristics to understand mineral transformations and slag formation
Van Dyk, J.C.; Waanders, F.B.; Benson, S.A.; Laumb, M.L. (Elsevier, 2009)A knowledge of the composition and structure of minerals in coal is necessary in order to understand the mineral transformations and agglomerate or slag formation during combustion or gasification. Coal ash fusibility ... -
Viscosity predictions of the slag composition of gasified coal, utilizing FactSage equilibrium modelling
Van Dyk, J.C.; Waanders, F.B.; Benson, S.A.; Laumb, M.L.; Hack, K. (Elsevier, 2009)Agglomeration of ash particles provides the desired porosity of the ash bed for adequate agent (steam and oxygen) flow and distribution, whereas excessive slagging inside the gasifier can cause channel burning, pressure ...
