摘要： A method of producing reduced metals is disclosed in which a mixture of a metal oxide and a reducing agent is heated by a burner such that the metal oxide is reduced to a reduced metal. Dry-distilled gas generated during carbonization of an organic matter-containing component is used as fuel for the burner. The sensible heat of exhaust gas evolved by the burner is utilized as heat for carbonizing the organic matter-containing component. Carbide derived by carbonizing the organic matter-containing component is used as the above reducing agent. This method yields excellent cost performance. An apparatus for reducing metal oxides is also disclosed.

摘要： A system provides assistance in the delivery of industrial wastes from industrial waste-generating sites to one or more industrial waste treatment sites based on exchanged information on industrial wastes containing metal oxide. The system includes a server, terminals at the industrial waste-generating sites, and terminals at the industrial waste treatment sites. Each terminal at the industrial waste-generating site transmits the information on industrial wastes to the server. The server stores the transmitted formation into an information storage unit. The server receives the search conditions from one of the industrial waste treatment sites who require industrial wastes, search the information storage unit, and transmits the search result to the terminal at the corresponding industrial waste treatment site. The terminal at the industrial waste treatment site displays the search result.

摘要： A method for operating manufacturing equipment including a heating furnace is provided. The method comprises the step of spraying a blowdown water that has been in the manufacturing equipment into effluent gas discharged from the heating furnace so as to vaporize the blowdown water and remove solid dust contained in the effluent gas. In a plant implementing this method, the amount of the effluent water can be reduced to substantially zero, no purification equipment is required, and solid sludge which has been produced in the purification equipment is thus completely reduced. Moreover, in this method, iron and zinc can be recycled as fly ash which can be easily treated and recycled.

摘要： The present invention provides a method for producing a high-quality reduced metal using an upgraded coal as a carbonaceous material to be incorporated. In the method, coal is first aged by heating in an organic solvent to produce upgraded coal for metallurgy having higher thermal plasticity than that of the coal. Then, a mixture of the upgraded coal for metallurgy and a metal oxide-containing raw material is agglomerated by an agglomerator, and the resultant agglomerates are reduced by heating in a furnace and then melted by further heating to produce a reduced melt. The reduced melt is cooled and solidified in the furnace to produce a reduced solid. The reduced solid is discharged to the outside of the furnace and slag is removed using a screen to recover a metal as a reduced metal.
