Study on Rapid Determination of Dry Basis Perch Calorific Value of Coal Based on Monochromatic Wavelength Dispersive X-ray Fluorescence Spectroscopy
In this paper,monochromatic wavelength dispersive X-ray fluorescence spectroscopy(MWD XRF)was used to determine the calorific value of coal,coping with the insufficient detection limit of metal oxides by conventional X-ray fluorescence spectroscopy.Multiple linear regression analysis was used to establish a calorific calculation model to solve the problem of matrix interference and quantification of coal.Combined with the characteristics of X-ray fluorescence spectroscopy of being non-destructive and easy-to-operate,the rapid quantitative detection of calorific capacity of coal was completed.This study satisfies the needs of rapid detection of calorific value of coal,and provides a rapid calorific detection method for all links and processes from coal production,circulation to customs clearance.
