    摘要
  • 摘要: 通過程序升溫實驗研究了煤炭的自燃特性,測定了不同粒度煤樣在不同溫度下產生CO,CO2等氣體的濃度.討論了指標氣體的選擇,分析了CO,CO2等氣體濃度隨溫度的變化規律,得到了耗氧速度與煤溫及煤體粒度的關系.結果表明,煤體粒度越小,溫度越高,則煤氧復合的強度越大.本實驗的研究結果對煤礦火災的防治具有指導作用.

     

    Abstract: The characteristics of coal spontaneous combustion were investigated through programmed temperature experiment and the concentration of CO, CO2 etc for coal with various sizes was measured at different temperatures. The selection of index gases was discussed. The law of concentration change for CO, CO2 etc and the relation of consuming oxygen velocity to coal temperature and size were analyzed. The smaller the coal size and the higher the temperature, the more intense the reaction of coal and oxygen. The results can direct the prevention and treatment of fire in mine.
