本文报告了从粉状燃料（煤和石油焦）中检验废料（飞灰和底灰）的爆炸性的实验结果。对单独的飞灰和底灰以及选定的与燃料混合的飞灰进行了试验。研究的爆炸参数为爆炸压力和压力上升速率。飞灰没有显示出爆炸的倾向，而底部的灰烬之一却显示出有限的爆炸性。这两个发现都可以用灰烬的挥发物含量来解释。煤或石油焦与粉煤灰的混合可产生挥发分含量在7-13%之间的爆炸性混合物，其值取决于混合物组分的组成和它们的粒度。
This paper reports the results of experiments done to examine the explosibility of the waste products (fly ash and bottom ash) from pulverized fuels (coal and petroleum coke). Tests were conducted for the fly and bottom ashes alone and also for selected fly ashes blended with the fuels. The explosion parameters of interest were explosion pressure and rate of pressure rise. The fly ashes showed no propensity to explode, whereas one of the bottom ashes did show limited explosibility. Both findings can be explained with reference to the volatile matter content of the ashes. Admixture of either coal or petroleum coke with fly ash resulted in explosible mixtures at volatile contents in the range of 7–13%, with the value being dependent on the composition of the mixture components and their particle sizes.
