摘要
通过煤样的热解、干馏、挥发分以及燃烧率测定实验,研究了温度对府谷长焰煤挥发分析出规律的影响。试验结果表明:当温度大于260℃时,挥发分才逐渐开始少量析出;当温度大于400℃时,煤样中大量析出的挥发分开始燃烧;当温度大于700℃时,挥发分已大部分析出且燃烧完全。
The temperature influence on the volatile precipitation regularity of Fugu long flame coal was studied through the tests of coal pyrolysis,destructive distillation,volatile and combustion rate in the paper.The tests showed that the volatile began to gradually precipitate at 260℃,the precipitated volatile in coal sample began to burn at 400℃,and most of volatile precipitated and burned out at 700℃.
