3-stage fluidized bed type fine iron ore reducing apparatus having x-shaped circulating tubes |
| abstract |
Disclosed is a 3-stage fluidized bed type iron ore reducing apparatus with X-shaped circulating tubes for improvement of gas utilization rate and reducing rate and decreasing of gas consumption rate. The apparatus comprises a first (10) and a second (20) fluidized bed furnace for drying and preheating raw fine ore, a first (60) and a second (70) cyclone for collection of the fines of the exhaust gases of said fluidized bed furnaces (10, 20) and recirculate them, a twin type third fluidized bed furnace (340) consisting of a first (30) and a second (40) reaction furnace for separating the ore in a coarse and a fine ore fraction so that these fractions are finally reduced in separate reactors and a third cyclone (80) for separation of the fine ore from the exhaust gas of said second reactor (40) of said third furnace (340) and recirculate it to the first reactor (30) of said third furnace (340). |
