Experience and discussion on determination of coal spontaneous combustion tendency using chromatography oxygen absorbing determination method
ZHANG Jin-jing
Abstract：Combining with practical experience of using chromatography oxygen absorbing determination method to do coal spontaneous combustion tendency test,and from aspects such as sample size,equipment stability,flow rate calibration and determination,pretreatment degree of sample and blocking of gas route,the measures and notice in determination of oxygen quantity absorbed of coal were discussed,so the accuracy of coal spontaneous combustion tendency test could be improved.
