Coal to Ash Calculation (Volume) - CR4 Discussion Thread

2014年2月4日  I would be very surprised if bottom ash of any coal and burning process would be 1/5 of the original volume or weight of coal. The resulting final density (mass divided by volume) of bottom ash maybe nominally 1/5 of the density of coal. I would expect many numbers of metric tons of coal would have to be burned to produce one kilogram of bottom ...

Bituminous Coal – Density – Strength – Melting Point – Thermal ...

Density of Bituminous Coal. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume.It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance.
