Walnut Shells as a Potential Fuel for Iron Ore Sintering

Iron ore sintering is a predominant process for fine iron and its concentrate to be applied in the blast furnace process. However, produces negative impact on environment. One of effective ways reduce greenhouse gas emissions from use CO 2 -neutral biomaterials fuel needs this technology. Walnut shells (WNS) are promising raw material such substitute. Herein, effect pyrolyzed WNS with constant fineness 3-0 mm sinter properties were studied. The proportion composition was set 25 wt.%. It has been established that up 873 K optimal. Additionally, difference reactivity coke breeze provoked studies influence size 1-0, 3-0, 5-0, 7-0 mm. found most optimal both quality particle mm, subjected preliminary pyrolysis K.
