Abstract

Kinetics of iron ore fines reduction in a fluidized bed was primarily studied and discussed by using Kunii-Levenspiel model. The results showed that the diameters of bubbles in the fluidized bed became more larger with the increment of dense bed height, while (K_bc)_b and (K_ce)_b decreased. (K_bc)_b was bigger than (K_ce)_b. Reduction speed of small granularities varied little in the direction of dense bed height, and speed of larger one reduced when a special reduction degree was reached, and its speed was less than the one of small granularities.
