To show the validity of the selected operational settings, the SWGR was introduced in an iron ore sinter plant. The simulated stack gas characteristics are compared with stack gas measurements of a sinter plant before and after its SWGR introduction. The measured data show a significant variation of the stack gas flow compared to its average value.
