水分在煤低温氧化过程中的影响研究

通过理论分析和实验研究相结合的方法,分析了水分与煤低温氧化阶段升温进程和产热速率的关系,并基于分形维数研究了水分对煤孔隙结构的影响,讨论了水分在煤氧化学反应中所起的作用,最后就水分对煤低温下吸氧速度和吸氧量的影响进行了探讨,对进一步加深对煤低温氧化过程的认识和准确对煤的自燃倾向性进行鉴定具有十分重要的意义。

Study on Influence of Water on Low - temperature Oxidation of Coal

Through the theoretical analysis and experimental study,the influences of water on temperature-rise process and heat-produce rate in the stage of low-temperature oxidation of coal were analyzed.In the basic of fractal dimension,the impact of water on oxygen adsorption of coal was studied.Meanwhile,the study pointed out that water played important role in coal-oxygen chemistry reaction.And at last,the effect of water on oxygen-absorbed rate and oxygen-absorbed capacity in the low temperature was discussed.This paper has vital importance in understanding the low-temperature oxidation process of coal further and appraising the tendency toward spontaneous combustion.
