Abstract
A method for the online determination of the ash content of a substance conveyed on a conveying device, includes a first measurement for determining the mass per unit area of the substance and a second measurement for determining the mean atomic number of the atoms present in the substance. An additional X-ray fluorescence measurement is carried out.
Claims22
A method for the online determination of the ash content of a substance conveyed on a conveying means, involving a first measurement for determining the mass per unit area of the substance and a second measurement for determining the mean atomic number of the atoms present in the substance,
- characterized in that an additional X-ray fluorescence measurement is carried out.
A device for realizing a method for the online determination of the ash content of a substance conveyed on a conveying means, comprising a first X-ray or gamma ray source (20) with an associated first transmission detector (22) and a second X-ray or gamma ray source (24) with an associated second transmission detector (26) and an X-ray fluorescence detector (28), wherein the first X-ray or gamma ray source (20), the first transmission detector (22), the second X-ray or gamma ray source (24), the second transmission detector (26) and the X-ray fluorescence detector (28) are rigidly connected to a gliding or floating element (50), which is arranged movable with respect to the conveying means, such that it glides or floats along the conveyed substance (S), and wherein the first X-ray or gamma ray source (20), the second X-ray or gamma ray source (24) and the X-ray fluorescence detector (28) are arranged above the conveying means and the first and the second transmission detector (22, 26) are arranged below the conveying means.
