【摘要】：煤經(jīng)水浸泡后的自燃特性會(huì)發(fā)生變化,為了研究水浸煤的自燃特性,采用煤自燃程序升溫實(shí)驗(yàn)裝置,進(jìn)行經(jīng)過(guò)3個(gè)月水浸泡煤樣和原煤樣的程序升溫實(shí)驗(yàn),研究煤的自燃特性。計(jì)算了兩種情況下煤樣的耗氧速率、放熱強(qiáng)度,得出了煤自燃極限參數(shù)和表觀活化能。煤經(jīng)水浸泡后,煤分子的表面活性官能團(tuán)增加,低溫階段的氧化放熱性增強(qiáng),自燃危險(xiǎn)性增大。
[Abstract]:The spontaneous combustion characteristics of coal will change after soaking in water. In order to study the spontaneous combustion characteristics of water-immersed coal, the temperature programmed heating experiments of coal and raw coal samples after 3 months water immersion were carried out by using the coal spontaneous combustion program heating test device. The characteristics of spontaneous combustion of coal are studied. The oxygen consumption rate and exothermic intensity of coal samples are calculated under two conditions, and the limit parameters and apparent activation energy of coal spontaneous combustion are obtained. The surface active functional groups of coal molecules increase after the coal is soaked in water. At low temperature, the oxidation exothermic property is enhanced, and the danger of spontaneous combustion is increased.
