摘要: 在热天平上进行黑液水煤浆和原煤的燃烧、热解实验，得到不同升温速率下的燃烧、热解特性曲线和碳转化率特征曲线。试验结果表明，黑液水煤浆中的钠及其化合物在燃烧过程中催化作用明显，并且黑液中有机物成分对燃烧起到一定促进作用。在20 ℃/min升温速率下黑液水煤浆和原煤的燃烧活化能分别为12.98 kJ/mol和106.59 kJ/mol，反映出黑液水煤浆比原煤有更好的着火特性。

Abstract: 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.-
