测定煤自燃倾向的方法中除氧化速度常数外,还应考虑三个因素:可碎性、自燃临界温度和氧的吸收热量。前两种因素是用色谱方式的脉冲反应堆中取得的。实践证明这种方法提高了测定的可靠性,但也存在不足。例如,测定标准中没考虑到湿度、瓦斯含量和热传导性。在开采煤炭过程中煤与
In addition to the oxidation rate constant, the method of determining spontaneous combustion tendency of coal should also consider three factors: friability, the critical temperature of spontaneous combustion and the absorbed heat of oxygen. The first two factors were achieved by using a chromatographic pulse reactor. Practice has proved that this method improves the reliability of the determination, but there are also shortcomings. For example, humidity, gas content, and thermal conductivity are not considered in the measurement standards. Coal and coal in the process of mining coal
