  • Fuel Gases used in Steel Industry – IspatGuru

    Jul 20, 2021During the process of steelmaking in the BOF, converter gas is generated at a rate around 75 cum to 95 cum per ton of crude steel. The CV of the converter gas varies in the range of 1,600 kcal/N cum to 2,400 kcal/N cum. It is the function of the air ratio. Lower is the air ratio higher is the CV, since N2 percentage of the gas reduces.
