Particle size distribution characterization by median particle size by volume, tenth percentile particle size by volume, and ninetieth percentile particle size by volume. Analytical procedure Subbituminous coal was crushed and sieved into fractions less than 0.25 mm, 0.25–0.8 mm, and larger 0.8 mm.
The size and ash content analysis of the raw coal are shown in Table 1.It shows that 80% of the raw coal has a particle size less than about 10 mm and as expected ash content of the raw coal increases with decreasing particle size.
However, in referring to particle size of airborne dust, the term "particle diameter" alone is an over simplification, since the geometric size of a particle does not fully explain how it behaves in its airborne state. Therefore, the most appropriate measure of particle size, for
COAL FLY ASH Material Description. ORIGIN. ... The particle size distribution of most bituminous coal fly ashes is generally similar to that of a silt (less than a 0.075 mm or No. 200 sieve). Although subbituminous coal fly ashes are also silt-sized, they are generally slightly coarser than bituminous coal …
Coal with larger particle size had higher ash content and higher helium density. The sorption isotherm was found to be highly sensitive with helium density of coal which was determined in the procedure of testing the void volume of sample cell.
