摘　　要：利用热重分析仪获得了升温速率分别为10 K/min、30 K/min、50 K/min和70 K/min下锡林浩特褐煤的燃烧失重特性曲线,计算了着火温度、燃尽温度、最大失重速度等燃烧特性参数。采用Coats-Redfern法计算出反应动力学参数:活化能E和频率因子A。结果表明,随着升温速率升高,其着火温度降低,燃尽时间增加。The combustion characteristics of Xilinhaote lignite were studied by thermogravimetric analysis at different heating rate （ 10 K/min,30 K/min ,50 K/min and 70 K/min）. The initiation point, burnout time, burnout temperature and maximum weight loss rate were calculated with the test date. The kinetic parameters, activation energy E and frequency factor A, were studied by Coats - Redfern thermalanalytieal method. Results show the burnout time increases and the ignition temperature decresaes with rising heating rate.
