被SCI检索 摘要 The proneness to spontaneous combustion can reflect the complexity of coal spontaneous combustion. It should be a process amount that can reflect the changing process of coal from the initial oxygen uptake thermogenesis to the beginning of accelerated oxidation. And the activation energy is exactly the process indicator which can weigh the complexity of this process. Therefore, this paper has collected some coal sample from the 15th coal seam of Jiarui coal mine, and used the differential scanning calorimeter to conduct the low-temperature oxidation thermoanalysis experiment of coal under the condition of different coal particle size, different heating rate and different oxygen concentration. According to Arrhenius equation, we have analyzed the characteristics of coal oxidation reaction and deduced the computing method of activation energy of the coal low-temperature oxidation process. According to the method we have calculated activation energy of the coal low-temperature oxidation process under the different experimental conditions. The experimental result shows that the smaller the coal particle size is, the smaller the predictive value of coal activation energy will be, and the easier to catch fire, namely the spontaneous combustion tendency will increase. And the bigger the heating rate is, the bigger the predictive value of coal activation energy will be. The coal activation energy is increased along with the oxygen concentration decreasing, namely the spontaneous combustion tendency will decrease. 关键词 作者关键词:activation energy; differential scanning calorimeter; particle size; ratio of nitrogen-oxygen KeyWords Plus:LOW-TEMPERATURE OXIDATION; CARBONACEOUS STOCKPILES; AIR 作者信息 通讯作者地址: Zhu, JF (通讯作者) North China Inst Sci & Technol, Hebei Prov Key Lab Mine Disaster Prevent & Contro, Yanjiao 065201, Hebei, Peoples R China. 地址: [ 1 ] North China Inst Sci & Technol, Hebei Prov Key Lab Mine Disaster Prevent & Contro, Yanjiao 065201, Hebei, Peoples R China [ 2 ] North China Inst Sci & Technol, Sch Safety Engn, Yanjiao 065201, Hebei, Peoples R China 电子邮件地址:bj_zjf@126.com 基金资助致谢 基金资助机构 授权号 Fundamental Research Funds Project of Central Universities of China 3142013116 查看基金资助信息 出版商 DISASTER ADVANCES, SECTOR AG-80, SCHEME NO 54, VIJAY NAGAR, A B RD, INDORE, 452010, INDIA 类别 / 分类 研究方向:Geology; Meteorology & Atmospheric Sciences; Water Resources Web of Science 类别:Geosciences, Multidisciplinary; Meteorology & Atmospheric Sciences; Water Resources 文献信息 文献类型:Article 语种:English 入藏号: WOS:000328669400035 ISSN: 0974-262X 电子 ISSN: 2278-4543 期刊信息 Impact Factor (影响因子): Journal Citation Reports® 其他信息 IDS 号: 275IL Web of Science 核心合集中的 "引用的参考文献": 31 Web of Science 核心合集中的 "被引频次": 0 |
