Making Iron Directly From Concentrate by Gaseous Reduction
The pilot flash reactor was equipped with 3 burners: a preheat burner, the main burner, and a plasma burner. The main burner was designed to make a swirling flow in the reactor. Swirl was introduced to increase the residence time of the magnetite concentrate particles, thus increasing the reduction degree.
