| 摘 要： | 从工业安全角度出发,对实验煤样进行了元素分析和工业分析,在高德伯儿格-格瑞瓦尔德炉中对潞安常村、漳村贫瘦煤的最低着火温度进行了比较全面、系统的实验研究,探讨了煤粉质量浓度、喷吹压力以及粒度对最低着火点的影响.结果表明,最低着火温度随煤粉质量浓度的减小而升高,随喷吹压力和煤粉粒度的增大而升高.对实验数据进行线性回归分析,得出影响因素与最低着火温度的函数关系,从而为贫瘦煤工业应用的安全性提供了一定的参考依据.

| Abstract: | In view of safety the elementary and industrial analyses of coal samples were conducted,a systematic experiment was performed to investigate the minimum ignition temperature (MIT) of Zhangcun and Changcun meager-lean coal in a G-G furnace,and the effect of dust concentration,spray-air pressure and dust particle size on the MIT was analyzed. The results show that the TIM increases with the decrease of dust concentration and the increase of spray-air pressure and dust particle size. A linear regression was conducted and the functional relationship was found,which can afford reference for the security of meager-lean coal's industry application. |
