INFLUENCE OF THE CHEMICAL AND MINERALOGYCAL ASH COMPOSITION OF COAL BLENDS FOR PCI IN THE BEHAVIOR OF FUSIBILITY AND VISCOSITY AT HIGH TEMPERATURES

INFLUENCE OF THE CHEMICAL AND MINERALOGYCAL ASH COMPOSITION OF COAL BLENDS FOR PCI IN THE BEHAVIOR OF FUSIBILITY AND VISCOSITY AT HIGH TEMPERATURES

Some aspects of permeability deterioration in blast furnace process at high rates of pulverized coal injection are not well known yet. At operational practice variations in the ash quality of injected coals can affect the furnace performance. Previous work has investigated the behavior of individu...
