Description

The solids weight fraction of coal in aerated coal slurries can be determined by a technique based on measuring the hydrogen per unit weight in the slurry. A neutron probe determines hydrogen per unit volume based on moderation of fast neutrons from an 241Am/Be neutron source. A γ-ray transmission probe determines density and mean atomic number of the slurry by measuring transmission of 356 KeV and 60 KeV γ-rays. With these two probes immersed in a 200 L drum containing coal slurries, their combined outputs determined solids weight fraction to +-1.3 wt% solids over a range of 0-36 wt% solids and aeration 0-3% by volume
