原煤和黑液水煤浆燃烧特性的热分析对比研究

Pyrolysis and combustibility of coal and coal black liquor slurry were studied on the thermobalance. The characteristics of pyrolysis, combustion and carbon conversion are all obtained under different heating rates . It is shown that the combustion of coal black liquor slurry is catalyzed by sodium and its compound ,and also the organic matter composition plays a certain role in the burning of coal black liquor slurry. The activation energy of coal and coal black liquor slurry combustion at the heating rate of 20 ℃/min are 12.98 kJ/mol and 106.59 kJ/mol, respectively ，which indicates that the combustion characteristic of coal black liquor slurry is better than that of coal.
