| 摘 要： | 用热重方式进行了煤在常规条件下的热重实验,分别用TG/DTG曲线描述了煤燃烧的整个过程,分析了煤升温氧化过程的特征参数,得到了各种煤的着火温度等特征温度.结果表明,煤样的特征温度与挥发分存在一定的规律性,特征温度下的失重值受挥发分的影响,着火温度随挥发分增加呈线性下降.

| Abstract: | Thermogravimetric analysis of coal samples is carried out under conventional conditions.The whole combustion processes of the coal samples are described with TG and DTG curves,and characteristic parameters of the heating and oxidation processes of coals are analyzed.The catching fire temperature and other characteristic temperatures are found.It is indicated that the characteristic temperature is related to volatile substance of coal.The value of weightlessness is affected by volatile substance of coal.The catching fire temperature is fallen when the volatile substance increase. |
