摘要
在预氧化过程中,会产生温度分布变化,从而影响煤的自燃特性规律.通过进行常温氧化试验对不同预氧化温度煤体的煤心温度变化、CO和CO2等指标性气体变化进行分析,得出随着预氧化温度的提高,会促进煤体发生自燃的结论,并对其产生的可能环境原因进行了分析和探讨.
Abstract
In the process of preoxidation,the temperature distribution will change,which will affect the spontaneous combustion characteristics of coal.Through the normal temperature oxidation test,the changes of coal core temperature,CO,CO2 and other index gases of coal at different preoxidation temperatures were analyzed.The conclusion was that spontaneous combustion of coal will be promoted with the increase of preoxidation temperature,and the possible environmental reasons were analyzed and discussed.
