Theoretical Combustion Temperature in Blast Furnaces

Abstract

Various methods of calculating the combustion temperature with pulverized-coal injection are analyzed. On that basis, the method that best corresponds to current blast-furnace operating conditions is selected. Calculations of the theoretical combustion temperature with variation in the rank and characteristics of the coal confirm the need for constant monitoring of the coal’s physicomechanical properties. That improves the stability of blast-furnace operation.
