Abstract: Opportunities for saving energy in blast-furnace operation are discussed. Among the most important are improving the processes of pellet making and sinter making, reducing sulfur inputs, restricting the variability in the characteristics of the iron ore raw material, prereducing the iron ore outside the furnace, and increasing the internal pressure in the blast furnace. Quantitative estimates of the effect on the coke rate of small changes in conventional parameters of blast-furnace operation are presented. The discussion concludes with a consideration of the use of supplementary hydrocarbons (natural gas, residual oil, reducing gases from steam conversion or fuel pyrolysis, pulverized coal) to displace coke, and it is explained that, except in the case of pulverized coal, heat must be added to compensate for the low enthalpy of exiting gases; blast-gas enriched in oxygen is helpful.
