摘要
结合采用色谱吸氧鉴定法测定煤自燃倾向性的实践经验,从样品粒径、仪器稳定性、流量的校准和测定、样品的预处理程度、气路堵塞的处理等方面探讨了测定煤吸氧量过程中需注意的问题及其相应的处理方法,以提高煤自燃倾向性检测结果的准确性。
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.
