Measurement of Activation Energy of Coal Oxidation at Low Temperature by Spontaneous Combustion Experiment

Activation energy of coal oxidation at low temperature is an important index to analyze spontaneous combustion character of coal.The text proposes a new measuring method of activation energy of coal oxidation at low temperature by using small-sized spontaneous combustion experimental table with heating power.Activation energy of coal oxidation with different tendency of spontaneous combustion and size can be measured.Furthermore,the relationship of activation energy with dynamic oxygen consumption and size is studied.The activation energy can be measured exactly by spontaneous combustion experiment.The result can fit for the practical character of coal oxidation and reflect the tendency of spontaneous combustion of coal well.
