Several recent studies have shown the potential of oxy-fuel combustion to reduce NO_x(gas) and SO₂(gas) emissions. However, the mechanisms through which SO₂(gas) reduction takes place has yet to be fully understood. Therefore, the development of oxy-sulfate thermodynamic database for a better understanding and control of SO₂(gas) emission during oxy-fuel combustion processes is essential. The focus of this research is on the thermodynamic modelling of the iron oxide–sulfate system with the FactSage 7.2 software package. Thermodynamic properties of selected phases in the FeO_x–FeSO₄–Fe₂(SO₄)₃ system were critically reviewed, compiled and assessed over a wide temperature range (298–2000 K) to obtain accurate thermodynamic description of the system at different temperatures. New C_p functions, which include the recent experimental data, were optimized. The obtained results are presented and discussed.
