The combustion and pyrolysis of coal is a very complex process including pyrolysis, volatile combustion and coke burnout. There are many homogeneous and heterogeneous chemical reactions in this process. In this paper, the thermodynamic equilibrium calculation model is used to predict the possible speciation distribution and chemical reaction mechanism of mercury and sulfur in coal combustion and pyrolysis. This will provide a theoretical basis for the removal of mercury and sulfur by mild thermal upgrading of coal before combustion and the control of mercury and sulfur emissions during coal combustion.
