BLOWING APPARATUS OF REDUCTION GAS FOR FLUIDIZED REDUCTION FURNACE

摘要

The present invention relates to a reduction gas blowing device for a fluidized reduction furnace. The reduction gas blowing device for a fluidized reduction furnace capable of supplying reduction gas to a fluidized layer formed above a distribution plate having a passage comprises: a flange which is attached to the top of the distribution plate, and which has a hole communicating with the passage; a nozzle having the upper part coupled to the flange and the lower part positioned inside the passage to guide the reduction gas to the fluidized layer; and a gas guiding pipe coupler composed of two or more gas guiding pipe single units positioned under the nozzle and attached to the inner surface of the passage to guide the reduction gas to the nozzle. The outer surface of the nozzle is formed in parallel to the passage. The inner surface of the nozzle is tapered with the diameter gradually narrowed in the inflow direction of the reduction gas.
