In order to study new alternatives for the sintering, the use of gaseous fuels has provided a significant reduction in the consumption of solid fuels, and also propitiates better quality control of physical and metallurgical sinter properties. In this study, a sintering model is proposed to evaluate the injection of coke oven gas in the process. We analyze five cases of coke oven gas injection always seeking a stable operational process. The simulation results indicate a lower consumption of solid fuel with the injection of coke oven gas and an increase of the combustion front. As a result, this increased the fraction of calcium silicates, which consequently improved the reducibility and also reduced the amount of CO2 in the output gas.
