Based on the principle of thermodynamic equilibrium, reactions between heavy metals As, Se and Pb in flue gas of coal burning and main minerals CaO, Al₂O₃, Fe₂O₃ and MgO in fly ash were studied. The results show that As reacts with CaO at 1600 K to form Ca₃(AsO₄)₂, and its temperature range becomes narrower with increasing CaO concentration, indicating that CaO can inhibit volatilization of As in coal. As reacts with Al₂O₃ at 1700 K, reaction of As with Fe₂O₃ forms FeAsO₄. As and MgO exist in the form of Mg₃(AsO₄)₂(s) between 600 and 1500 K, and turns into As₂O₅(s) below 600 K. Se and CaO, MgO exist in the form of CaSeO₃(s) and MgSeO₃(s), respectively, below 600 K, but does not react with Al₂O₃ and Fe₂O₃. CaO and Pb react at 900-1100 K to form (CaO)₂(PbO₂)(s). Pb reacts with Al₂O₃, and solid (PbO)(Al₂O₃)₆(s) is formed at 900-1200 K. Fe₂O₃ and MgO have no effect on species distribution of Pb.
