Determining the ash composition of coal by X-ray spectrometry

For timely determination of the ash composition in coal, chemical analysis has been replaced by X-ray analysis using a Spectroscan MAX-GV spectrometer at OAO Koks. That permits prompt determination of the ash basicity, which affects the reactivity and hot strength of the coke. The plant’s coal purchases are optimized to stabilize and improve the coke’s CSR and CRI values.
