The sintering process is a critical phase in ironmaking, where fine iron ore particles and additives are agglomerated. This process is primarily driven by coke combustion, which generates the flame front essential for the material transformation. While crucial for the material preparation, it is a significant source of CO₂. Integrating dynamic unit operation modeling with advanced flowsheeting techniques will be used, to provide a comprehensive solution for optimizing resource utilization and minimizing environmental impact in integrated iron and steel production. To better depict the process, a one-dimensional transient model of the sintering process was developed. The model incorporates mass, momentum, and energy conservation equations, assuming homogeneity in both solid and gas phases. Dirichlet and Neumann boundary conditions are applied at the inlet and outlet, respectively, with a no-slip condition at the gas-solid interface. The coke combustion mechanism was implemented following a gas-solid reaction pathway, beginning with the transport of reactant gases to the coke surface, diffusion through the porous solid, chemical reactions at the surface, and finally the release of gaseous products into the bulk gas stream. This framework enables a detailed simulation of the coke combustion process and its interaction with the sintering bed. The model is being validated using data from sinter pot tests, a scaled-down version of the sinter strand conducted under controlled conditions. While it successfully captured key process behaviors, confirming its ability to predict sintering dynamics, the coke combustion occurred only to a limited extent during the operational phase, which in turn slowed the advancement of the flame front. Further research into implementation of coke combustion is necessary to address challenges like incomplete combustion and heat distribution inefficiencies. Continued development and validation of this model will aid in refining strategies for optimizing coke usage, reducing CO₂ emissions, and improving overall sinter quality.
