The last ten years have seen a significant increase in the production and use of coal around the world. Associated with this increase in production has been a growing requirement for quick and accurate ash measurement..
The early part of this paper provides a brief description of the
Ash Probe but the main part provides a number of detailed case studies where this instrument has been used to significantly improve customer operations.

ver the past ten years since the first article appeared in World Coal, the
Ash Probe
has become a vital tool for many coal
producers and users in over 20 countries around the world.
This hand portable instrument provides quick and accurate
measurements of the ash content of coal in piles, trucks or wagons. It works
using the natural gamma technique, which makes use of the fact that the dirt
associated with mined coal contains significantly higher concentrations of
gamma emitting radioactive material than the coal itself.
The signal received in its sensitive gamma detector increases as the dirt (or ash) content
of the coal increases. Through a suitable calibration, the Ash Probe converts
this gamma signal into an ash reading.
