ISO 23499:2013(en), Coal ? Determination of bulk density ...

The present method describes a procedure for determining a reference bulk density for crushed coal such as that charged into coke ovens. When charging a coke oven, a knowledge of the mass of coal placed in the oven for maintaining a relatively constant oven charge is a requirement.

Coal Density - an overview ScienceDirect Topics

Coal density is typically less than that of conventional reservoirs and differs from seam to seam based on the given coal rank and purity. The bulk density of a coal consists of the matrix and the void space, with the latter being expectedly filled with water. The dry coal density, however, is only made up of matrix system density.

Effect of bulk density of coking coal on swelling pressure ...

2013-12-1  With the increase of the bulk density, the swelling press was improved significantly of Xinjian coal with weakly coking coal and high-volatile. And the swelling pressure obtained the maximum value of 82.9 KPa at the bulk density of 1.05 ton/m3, which is 13 times value of 0.7 ton/m3 and the swelling pressure changed a lot during pyrolysis.
