Abstract: An apparatus and process for treatment of metallized iron ore produced by direct reduction techniques principally for use in various iron and steelmaking furnaces. The apparatus and process receives the product from a direct reduction facility consisting of hot metallized fine sizes of reduced iron ore such as from a fluidized bed reactor system that can be combined with metallized iron ore pellets or like agglomerates from other types of direct reduction reactors. The present invention involves dry and wet treatment and handling apparatus and procedures wherewith the hot metallized fine sizes, optionally including metallized pellets or agglomerates, are rendered immune from reoxidation and degradation for unlimited periods of time whether in open storage or during transport, whereafter the stabilized product can be readily used in various types of iron and steelmaking furnaces.

Abstract: A fluidized bed reactor preferably for high temperature and pressure operations featuring reactor components and constriction plate arrangements therein capable of essentially unlimited size scaleup, the invention avoiding common reactor design and operational problems usually associated with the high temperature and pressure properties of metallic materials of construction such as: thermal expansion, creep, strength and stress-to-rupture. The present invention includes features for uniformly distributing multiple gaseous, liquid, or solid reactants and fuels into a fludized bed avoiding problems of coking and plugging of distribution pipes and tuyeres due to high temperatures. The present invention is useful for high temperature and pressure combusation, reforming, gasification, reduction, drying and calcination reactions.
