摘要： A method for producing reduced iron in a layered furnace which includes several superimposed layers. Ore is continuously fed into the layered furnace, deposited on the uppermost layer, and gradually transferred to the lower layer. A reducing agent is deposited on the uppermost layer and/or layers thereunder and is reacted with the ore in order to form directly reduced iron. The directly reduced iron and reducing agent residues are discharged in the vicinity of the lowest layer of the furnace.

摘要： The invention relates to a method for the heat treatment of residues containing heavy metals, carried out in a multiple-hearth furnace which is divided into three zones, each of which comprises several stacked levels. Said method consists of the following steps: continuous feeding of the heavy-metal residues into the top level of the first zone of the multiple-hearth furnace, the residues being gradually transferred to the second zone and dried during the transfer; continuous feeding of reducing agents and desulfurizers into the top level of the second zone, whereby the reducing agents and desulfirizers are mixed with the dried residues and the mixture is heated to approximately 800° C., calcined during heating and gradually transferred to the third zone; heating of the mixture to approximately 1000° C. in the third zone, whereby the metals are reduced and the waste gases resulting in said third zone are drawn off and treated separately; and discharge of the mixture from the multiple-hearth furnace.

摘要： The invention relates to a method for producing directly reduced, desulfurized iron in a multiple-hearth furnace which comprises two zones arranged one above the other and each having several hearths. Iron ore is reacted with a reducing agent in a first zone of the multiple-hearth furnace at a temperature ranging from 800° C. to 1100° C. to obtain metallic iron. In addition, the gases are desulfurized using desulphurizing agents, whereby the directly reduced iron is discharged from the multiple-hearth furnace and the desulfurized gases are guided into a second zone where the iron ore is preheated to a temperature ranging from 600° C. to 800° C.

摘要： A device in which a mixture of steam and contaminated air is first of all channelled into an upward stream and that the mixture subsequently flows as a downward stream in a vessel maintained at reduced pressure. The device further includes an arrangement for spraying an alkaline aqueous solution into the downward stream of the mixture of steam and contaminated air. The decontaminated uncondensed gases are thereby removed from the vessel by a forced and adjustable stream which creates and maintains a reduced pressure inside the vessel.

摘要： An isolation and flow control valve in a furnace charging installation, installed in a discharge conduit of a storage hopper which may be alternately at ambient pressure for loading and furnace pressure for discharging, is characterized by a valve member which is caused to move serially in two directions during opening and closing. The movement is produced by an actuator mechanism including a pivot arm and a cam system and results in movement axially with respect to the conduit for seating and unseating and generally transverse to the conduit axis for controlling material flow through the conduit.
