Emission reduction research and development of PCDD/Fs in

Iron ore sintering process is an important sector for iron and steel industry as well as a major pollution emission source of PCDD/Fs. The PCDD/Fs emission of sintering process has not been properly controlled because the flue gas presents the following characteristics, including large amount, remarkable flow fluctuations and lower concentration.

Low Temperature Sintering of Iron Oxides KRAMER 1978

To study agglomeration in iron oxides during low temperature sintering, submicron magnetite (Fe 3 O 4) powders were processed in air and in vacuum at 773, 793, and 843 K. Specific surface area measurements were used to monitor sintering progress. Oxidation of the magnetite altered the sintering kinetics, which were dominated by surface diffusion in this temperature range.
