大同塔山石炭二叠纪烟煤的TG-DTG分析
TG-DTG Analysis of Carboniferous Permian Bituminous Coal in Datong Tashan
摘要: 本文通过对中煤塔山矿3~5#层煤样的TG-DTG及红外光谱分析，找出了煤样氧化热解过程的着火点等特征温度点和最大增重比，得出了煤表面分子结构在不同温度下的增/失重微观变化和结构特征，对预防煤炭自燃发火提供了参考数据。
Abstract: Based on the analysis of TG-DTG and infrared spectroscopy of 3~5# layer coal from Tashan Mine of ChinaCoal, the characteristic temperature points and maximum weight gain ratio of ignition point of coal samples in oxidative pyrolysis process are found out in this paper, and the maximum weight gain ratio and ignition point of the coal samples are also determined. The microcosmic changes and structural characteristics of coal surface molecular structure at different temperatures are obtained, which provide reference data for preventing spontaneous combustion of coal.
