原始语种摘要: Abstract(#br)In this work, thermal behavior of five different coal particle fractions were investigated using thermogravimetric analyzer (TGA) under various heating rates with the maximum of 1000K/min. An on–line Fourier Transform Infrared Spectrometry (FTIR) was employed to evaluate the evolution characteristics of the gaseous products. The results showed that the coal particle size remarkably affected the mass loss and the ash amount. The larger the particle size was, the higher mass loss and the more ash could be, which revealed its high pyrolysis reactivity. In addition, with increasing the particle size, the initial devolatilization temperature (T in ) and devolatilization index (D i ) increased, whereas, the final devolatilization temperature (T f ) decreased....
