System and method for fluidized reduction of iron ore powder
摘要
A system and method for fluidized reduction of iron ore powder. Use of oxidation increases the iron ore reduction rate. Use of high-gas-velocity processing accelerates iron ore reduction speed and greatly improves the gas-treatment capabilities of a unit-cross-sectional fluidized bed. Use of parallel-connections involving reduced coal gas lessens the volume of gas passing through a single-stage fluidized bed. The invention achieves the highly-effective reduction of iron ore powder in a fluidized bed under near-atmospheric pressure.
