| 摘 要： | 在不同氧气浓度下煤的耗氧速度不同,从而使煤的自燃性产生差异.通过在不同氧气浓度条件下对煤样进行程序升温氧化实验,测定分析煤样在不同温度时的耗氧速度,研究氧气浓度对煤氧化自燃性的影响关系,提出了低氧气浓度条件下,煤样在不同温度时的耗氧可分为扩散耗氧和化学动力耗氧两个阶段.并根据实验数据分析,得出煤的耗氧速度与氧气浓度的1.149次方成正比.图4,表2,参7.

| Abstract: | Theoretically,for the development of the spontaneous combustion of coal,the air(or oxygen)must be flow into the place where coal is deposited.But the spontaneous combustion propensity is different with the concentration of oxygen.According to the experiments for many coal samples under the different concentration of oxygen,the relation of the velocity of oxygen consumption and the concentration of oxygen is analyzed and the nature of oxygen consumption of coal is discussed.The results are of importance to understand the process of spontaneous combustion of coal.4figs.,2tabs.,7refs. |
