摘要
在煤的氧化初期,少量的水促进煤的自燃,而大量的水则会抑制煤的自燃。由此可见,存在一定量的水分,能够使煤最易自燃。为探讨水分对煤自然发火的影响,我们采用DSC方法对煤在低温情况下进行分析。差式扫描量热法是程序升温控制温度下,测量输入到煤样和参比样的热流差随温度变化的一种技术。本实验最终得出了100℃以前不同水分对煤氧化初期的定量影响,初步得出了煤最易自燃临界水分。
In the initial stage of coal oxidation, little water can accelerate coal spontaneous combustion, and plenty of water can control it. So, some water can make coal spontaneous combustion most easy. To Probe into influence of water on coal spontaneous combustion, coal is analyzed in low temperature by DSC way. The result tell us the quantitative influence of different water before 100℃ in the initial stage of coal oxidation, and have got the critical water of Brown coal spontaneous combustion.
