基于CO的煤低温氧化性研究

oal spontaneous combustion is a slow oxidation process, with the development of oxidation, will produce a series gases witch reflect the characteristics of coal spontaneous combustion , with the rise of coal temperature, Volume of various gases will occur significant change, using the changes of gas generated, can do the early prediction of coal spontaneous combustion, underground spontaneous combustion of coal oxidation, The emission of CO changes in stability, can objectively reflect spontaneous combustion of coal development and changes of the basic law, and easy monitoring, using CO as an indicator of gas in this article, according to the variation to identify the spontaneous combustion of underground coal degree of oxidation parameters, in this article, based on past experiments, made a kind of low-temperature oxidation of coal experiment, select several medium-rank coal samples for the study, The purpose of this study is find the low-temperature oxidation process of coal in different coal particle size and experimental ventilation, Analysis the gas product yields of CO with the impact of experimental warming relations between the corresponding temperature.
