Abstract: The characteristics of separate combustion of gasification fine slag and its mixed combustion with raw coal were studied by the thermogravimetric analyzer. The effects of mixing ratio on combustion characteristics, and the interactions and reaction kinetics during combustion were investigated. The results show that there is a significant synergistic effect between gasification fine slag and raw coal. The higher the proportion of mixed raw coal is, the lower the activation energies of the combustion reaction of mixed fuel are, and the better the flammability and comprehensive combustion characteristics are. The obtained conclusions are of practical significance for improving the combustion characteristics of gasification fine slag, effectively utilizing the calorific value of gasification fine slag, and reducing the amount of solid waste.
