摘要:
为研究不同氧气浓度对煤自燃反应能级的影响,基于热重实验分别得到6个不同氧气浓度下的煤自燃特征温度点,通过计算不同阶段内煤自燃的反应动力学参数分析氧气浓度与煤自燃反应能级关系。实验结果表明:n≠1时,氧气浓度对煤自燃反应能级(n)的影响在不同温度段内的影响不同;氧气浓度与T1,T2,T3特征温度点的关系曲线变化趋势不明显,T4~T8温度点与氧浓度的关系呈现先增大后减小的趋势。
Abstract:
In order to study the influence of different oxygen concentrations on the reaction energy level of coal spontaneous combustion, six characteristic temperature points of coal spontaneous combustion under different oxygen concentrations were obtained based on the thermogravimetric experiments, and the relationship between oxygen concentration and reaction energy level of coal spontaneous combustion was analyzed through calculating the reaction kinetics parameters of coal spontaneous combustion in different stages. The results showed that when n≠1, the influence of oxygen concentration on the reaction energy level of coal spontaneous combustion (n) in different temperature segments was different. The change trends of the relationship curves between oxygen concentration and characteristic temperature points of T1, T2 and T3 were not obvious, while the relationship between oxygen concentration and characteristic temperature points of T4-T8 presented the trend of first increase and then decrease.
