对潞安集团一缘矿15#煤分别通入30%和60%2种不同浓度CO2气体,吸附24 h后,结合程序升温氧化和热重差热分析实验,研究煤样吸附CO2后耗氧速度、CO产生率、特征温度等自燃特性参数的变化规律。
The 15 # coal of the first margin of Luan Group was fed into two different concentrations of CO2 gas of 30% and 60%, respectively. After adsorption for 24 h, combined with programmed temperature oxidation and TG-DTA experiments, Speed, CO generation rate, characteristic temperature and other parameters of spontaneous combustion characteristics of the law.
