Fly Ash – Production, Variability and Possible Complete

minerals as well as other complex organic compounds in the coal, which give rise to ash, vary with the coal type The physical, chemical and engineering properties of fly ash from a particular plant or utility are contingent upon the inorganic chemical composition of the source coal, degree of coal pulverization, combustionThe segregation phenomena of macerals in coal during pulverization is probably due to the different inherent mechanical properties such as hardness, toughness and friability To illustrate the problem, the petrographic analysis of different SH coal samples is summarized in Table 1 , with the ultimate analysis also shown thereSize segregation behavior of heavy metals in superfine
