Web1.1.4.2.5 Coke Oven Gas. COG is a strong fuel but it is less useful compared to other injected fuels in the lower part of the blast furnace. COG contains H 2 = 60%, CH 4 = 24%, CO = 6%, CO 2 = 2%, and N 2 = 6%, but only carbon in CH 4 is oxidized in the raceway to CO releasing heat. CO 2 reacts with coke carbon to CO consuming energy, whereas H ... WebThe quantity known as net calorific value (NCV) (or lower heating value or lower calorific value) is determined by subtracting the heat of vaporization of the water vapour from the higher heating value. This treats any H 2 O formed as a vapour.
