Abstract :
Theoretical studies of the emission rule of SO2 and NOx during iron ore sintering was conducted, it is put forward that the emission of SO2 possesses the characteristics of self-sustaining which means the emission of SO2 rises to a peak value rapidly just before the sintering end point and then declines dramatically no matter how parameters of sinter technology and the properties of raw material change. It is also revealed that emission of NOx in sintering flue gas is originated primarily from the combustion of gas fuel during ignition and solid fuel in sintering bed. Compared with the emission rule of SO2 during sintering, the emission rule of NOx is quite different. From the finish of ignition to the end of sintering, the concentration of NOx in the flue gas always maintaines at a high level.
