A transient two-dimensional mathematical model is developed to study the influence of fuel type and operation parameters on combustion and NOx emission during the iron ore sintering process. The model was validated by comparing the model predictions with sintering pot test data. The predictions show reasonable agreement with the averaged values of the test data.

Effect of Iron Ores and Sintering Conditions on Flame Front J-Stage. In iron ore sintering, the properties of the flame front are clearly critical as they determine the heat imparted to the particulate bed and, hence, the strength of the formed sinter. This study causes the partial melting of a blended mix of ores, fluxes and coke measures required to maintain sinter production ...
