The low-temperature pyrolysis technology is being developed in China for upgrading the low-rank coal quality. However, abundant coal char is difficult to be utilized reasonably. Using the granular coal char instead of pulverized coal in the fuel injection of blast furnace is likely to be a promising approach for making use of the coal char. In this paper, the impact of particle size of coal and pyrolysis temperature on combustion reactivity of coal char was investigated. Coal particles with different sizes were heated by temperature programming to a definite temperature under an inert atmosphere, and then the produced coal chars were reheating during an oxidizing atmosphere for examining the combustion reactivity. The results show that the particle size of raw coal could be enlarged but still meet the demand of blast furnace for the combustion reactivity of fuel, in the event that the pyrolysis temperature was reduced.
