Coal and Its By-products

Some harmful trace elements in raw coal, ash, flyash, and superfine flyash from Shizuishan, Shangwan, Daliuta and Haibowan power plants were tested using INAA and ICP AES methods. Burning and migration behavior and its environment effect of As, Pb, Hg, Cd, Cr, Se, Mn, Ni, Co, U, Th, Be, Sb, Br were researched and their distribution and enriching characteristics in coal, bottom ash, flyash and superfine flyash were analyzed. The result shows that for elements Hg and As, the enriching coefficients, from great to small, are in the order of superfine ash, flyash, bottom ash.
