通过理论分析和实验研究，分析了水对煤低温氧化阶段升温过程和产热速率的影响，并以分形维数为基础，研究了水对煤氧吸附的影响，同时指出水在煤氧化学反应中起着重要作用，最后提出了水对煤氧吸附的影响机理。探讨了水分对煤低温氧化过程中吸氧速率和吸氧量的影响，对进一步认识煤的低温氧化过程和评价煤的自燃倾向性具有重要意义。
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.
