摘要
采用SDTQ600型差热分析天平,利用YG-DTG-DTA(即热重-微分热重-差热)热分析技术研究了新型黑液水煤浆的热分析特性,并与煤粉的燃烧特性进行了比较.结果表明,由复合液制取的水煤浆具有着火点较低,燃尽性能较好的燃烧特性;动力学分析得出各燃料表观活化能从大到小顺序为:永城无烟煤(YM)、平顶山烟煤(PM)、永城新型黑液水煤浆(YM-CWS)和平顶山新型黑液水煤浆(PM-CWS).
The text studied the thermal analysis character of the new model coal water slurry by thermal analysis and TG-DTG-DTA, than the combustion characteristic of coal has been carried out comparison . The thermogravimetric analysis on the new black liquid coal water mixture shows that the characteristics are the lower kindling point and the better property of burnout. Kinetics analysis shows that the activation energy is lower. The sequence is YM,PM, YM-CWS and PM-CWS.
