Mathematical model for post combustion in smelting reduction

Abstract: Post combustion in the top space of iron bath smelting reduction furnaces is analysed with three-dimensional mathematical modelling. Momentum transport and continuity equations in combination with a k-e model of turbulence are numerically solved for the gas flow field. Combustion reactions are modelled by a set of transport equations based on the SCAS combustion model and its extension to the k-f-g model. A two-stage combustion scheme is formulated to include carbon transfer and combustion. Heat transfer to ba… Show more

“…This model provided some insight into the fundamentals of the PC process for iron smelting. A threedimensional numerical model for a HIsmelt-type reactor was developed by Becker-Lemgau and Tacke [11] using an inhouse finite-volume code. The CFD modeling work [7,8,9] on the HIsmelt process considered the spatial variation of heat and mass transfer in the smelter.…”

“…[7][8][9]11] The mean mass fraction of the fuel, oxidant, and products are obtained from the mean and variance of the mixture fraction using an assumed form for the probability density function, including the single and double delta function and a beta function, of the mixture fraction. This is similar to models used in most of the previous studies.…”
