Consumption of residual char in blast furnace during coal injection - slag/carbon/gas interactions

摘要

One of the factors limiting the maximum rate of coal injection in the blast furnace is the accumulation of unburnt char. The interaction of unburnt char with slag, hot metal and the gaseous phases could have a significant influence on char assimilation. This work examines the interaction of a low iron oxide bearing slag with different carbonaceous substrates with varying levels of ash content (0.05
