The combustion characteristics of blast furnace bag dust (BD) and three kinds of coal—Shenhua (SH) bituminous coal, Pingluo (PL) anthracite, and Yangquan (YQ) anthracite—were obtained via non-isothermal thermogravimetry. The combustion characteristics with different mixing ratios were also investigated. The physical and chemical properties of the four samples were investigated in depth using particle size analysis, Scanning electron microscopy, X-ray diffraction, X-ray fluorescence analysis, and Raman spectroscopy. The results show that the conversion rate of the three kinds of pulverized coals is far greater than that of the BD. The comprehensive combustion characteristics of the three types of pulverized coals rank in the order SH > PL > YQ. With the addition of BD, the characteristic parameters of the combustion reaction of the blend showed an increasing trend. The Coats–Redfern model used in this study fit well with the experimental results. As the BD addition increased from 5wt% to 10wt%, the activation energy of combustion reactions decreased from 68.50 to 66.74 kJ/mol for SH, 118.34 to 110.75 kJ/mol for PL, and 146.80 to 122.80 kJ/mol for YQ. These results also provide theoretical support for the practical application of blast furnace dust for blast furnace injection.
