Effect of calcium-sodium composite flux on ash fusibility and mineral transformation of Pingshuo coal

This paper investigates the effect of calcium sodium composite additives on the melting characteristics of Pingshuo high ash melting point coal ash. X-ray diffraction (XRD), FactSage and other methods are used to analyze the evolution behavior of minerals at high temperatures, and molecular dynamics simulations are combined to reveal the influence of calcium sodium composite fluxes on the melting mechanism at the microscopic level. In file 1, the line markings represent different coal ash, different addition amounts, and different ratios, while the column markings represent the diffraction peak intensities corresponding to different temperatures The lines in file 2 are labeled with different fluxes, different addition amounts, and different ratios, while the columns are labeled with melting characteristic temperatures (AFTs) In file 3, the line markings represent different fluxes and ratios, and the column markings represent the phase distribution functions corresponding to different temperatures The rows in file 4 are marked as different chemical bonds, and the columns are marked as radial distribution functions In document 5, the line markings indicate different temperatures and ratios, while the column markings indicate volume or MSD
