Abstract：The ignition and combustion characteristics of Lu ' an coalslime water slurry (CWS) were studied through thermogravimetric apparatus, and its combustibility was compared with that of the coal water slurry samples made by a low-volatile-matter coal and a high-volatile-matter coal. The ignition and burnout temperature was obtained by TG-DTG method, and the reaction kinetics were analysed with Coats-Redfern method. The results show that the ligniton and burnout temperatures of Lu' an coalslime water slurry are higher than that of low-volatile-matter CWS and high-volatile-matter CWS; the combustibility of Lu'an coalslime water slurry is worse than that of lowvolatile-matter CWS and high-volatile-matter CWS by using signitability number. The dynamic analysis shows that at different conversion rate (12.5, 33.3, 50.0℃/min), activation energy E (120.89, 78.50, 71.48 kJ/mol) , Lu'an coalslime water slurry is higher than that of low-volatile-matter CWS and high-volatile-matter CWS.
