“…In addition to the previously researched operation conditions [1][2][3][4][5][6][7][8], four cases are selected for the optimization of sinter process and these are classified as follows: (1) selective oxygen enrichment, (2) double layers with oxygen enrichment, (3) elongation of bed height, and (4) LNG supply and FGR. At first, additional oxygen supply at the targeted location is shown in Fig.…”

Combustion of solid fuel supplies heat in an iron ore sintering bed and the quality and productivity of the processes are highly dependent on the variation of operational parameters. To set the optimized operation modes through the application of various ideas, a numerical model can be employed prior to the conceptual designing of the actual plant. In this study, the effects of oxygen enrichment, increment of bed height, waste gas recirculation, as well as supplementary gaseous fuel combustion are investigated by employing a previously developed unsteady onedimensional model of an iron ore sintering bed. Through the simulation, temperature distribution can be observed and used as the key data for the evaluation of the combustion efficiency. Flame front speed and sintering time, which represent propagation speed of the combustion zone, are also employed for quantification of the simulation. Through the parametric studies with numerical analysis, preliminary information about the detailed situation in the bed can be obtained.

“…One common method of hot gas recirculation is to return some of the waste gases from the flue gas treatment system to the bed over the length of the sintering machine. Vyatkin et al [8] carried out the assessment of the maximum permissible waste gas recirculation in terms of the environmental impacts of the sinter production system.…”
