Numerical Analysis of Sintering Bed Combustion; Applying Supplying Gaseous Fuel and Flue Gas Recirculation Processes

In the iron ore sinter process, temperature distribution pattern in sintering bed is related with productivity and quality of sintered ore. Evenly heat distribution make the uniform quality of sintered ore but in normal operating condition, upper part of bed has lack of heat and scarce quality of sintered ore, thus yeild rate is decreased and productivity is diminished. Therefore, using the additional fuel for increasing quality and flue gas recirculation for increasing productivity are considered and effect of both processes are discussed.
