【摘要】 采用水煤浆雾化悬浮燃烧实验装置对神木水煤浆悬浮燃烧过程煤焦颗粒的动态变化特性进行了研究,主要通过水煤浆雾化悬浮燃烧实验装置、Malvin激光粒度测定仪、SEM等分析手段,揭示了水煤浆燃烧煤焦颗粒的变化特性.实验结果表明:神木水煤浆在700,900℃燃烧时,残渣粒度及其圆形度急剧减小;而在900,1 000℃燃烧过程中,残渣颗粒的粒度、圆形度经历了燃烧反应初期迅速减小,燃烧反应后期又有所增大变化的过程.更多还原

【Abstract】 Atomization suspension combustion test device(ASCTD) was proposed and adopted to study dynamic characteristics of coal-coke granularity in Shenmu coal water-slurry(CWS) suspension combustion.The change rules of residue granularity in ASCTD were discussed with SEM,Malvin laser granularity apparatus.The results show that combusted residues and rotundity degree rapidly reduce while CWS combustion at 700 ℃ and 900 ℃.However combusted residues and rotundity degree rapid reduce in the initial stage of CWS combustion and increase in the later stage of CWS combustion along with the combustion temperature of 900 ℃ and 1 000 ℃.更多还原
