Abstract：The pyrolysis process of injection pulverized coal at Handan Steel was investigated by simultaneous thermogravimetry-fourier transform infrared (TG-FTIR). The results indicated that process of mass loss of Changzhi coal, Changzhi coal added with 30% Dawan coal and Dawan coal could be divided into three stages. The curves of TG decreased quickly and volatiles in sample released mostly at the range of 450-800℃. DTA curves reached the maximum and pyrolytic reaction was violent from 590℃ to 700℃. Experiment showed that the initial temperatures of Changzhi coal added with 30% Dawan coal could decrease 13.5℃, and mass loss rate of mixture coal increased 4.05% than that of Dawan coal. FTIR data suggested the effect of additive on CO content in pyrolysis process was small, while CO2 content went to reduce. The release of methane content increased. Mix coal could promote hydrocarbons gas release and enhance proportion of volatile gas for combustion.
