Natural gas injection is one of the two most popular hydrocarbon fuels in blast furnace use, second after pulverized coal injection. To understand the impact on blast furnace conditions, the injection of pure methane, CH4(g) is assessed. The impact of the hydrogen and added carbon is incorporated into the mass and enthalpy balances for the bottom segment. The impact on the oxygen and nitrogen in blast air is determined for CH4(g) injection. The C-in-coke replacement ratio is calculated and compared to the replacement ratio previously estimated for the injection of pure carbon through the blast furnace tuyeres.
