| Abstract Scope |
Flue gas recirculation sintering technology can reduce flue gas emissions and reuse waste heat effectively in iron ore sintering. A comprehensive mathematical model is established in this work to study the sintering performance of flue gas recirculation technology. The proposed model considers fluid flow, multiphase reactions and various heat transfer within/between different solid and gas phases.
Characteristic size distribution of raw materials including coke, limestone and dolomite are used to correct the reaction rates. Geometric changes caused by the reactive and melting factors are also considered in the model. The reliability of the model is validated by contrasting the modelling results and the experimental data from sinter pot tests. The simulation results indicate that flue gas recirculation sintering can increase the thickness of sinter bed over a reasonable temperature range, and making sintering process more stable. The NOx emission can decrease by around 15% compared to traditional iron ore sintering. |
