A rotary hearth furnace for reducing a feed material is disclosed. The rotary hearth furnace includes a rotating hearth disposed in an enclosure and mounted for rotary movement. The enclosure includes an annular inner wall, an annular outer wall and a roof. The enclosure is sealed to the hearth and divided into a plurality of zones including at least a loading zone, a process zone and a discharge zone. The furnace further includes a plurality of burners positioned in at least the outer wall of the enclosure to provide a controlled temperature within the rotary hearth furnace and a flue positioned within the reduction zone of the furnace between the preheat zone and the discharge zone to exhaust combustion gases from the burners and gases resulting from the processing of the feed material. Said flue contains space for combustion and settling of the unburned particulates. A water spray quench reduces the temperature of the furnace off-gas so that subsequent combustion by the introduction of air or oxygen does not produce significant nitrogen oxides.

A furnace discharge system for removing material from a hearth ( ) of a rotary hearth furnace ( ) and method of operation. The system includes at least two material discharge augers ( ) positioned above the hearth ( ) of the rotary hearth furnace ( ). Each discharge auger ( ) is operatively mounted to allow for height adjustment of the discharge auger ( ) in alternating sequence from a material removal position to an elevated material by-pass position.

A rotary hearth furnace for treating metal oxide materials comprises a hearth mounted for rotary movement within an enclosure. One or more fuel burners are positioned above the hearth. The burners are operably fired to heat the furnace so that heat radiates toward the hearth. One or more oxygen nozzles are positioned between the hearth and the burners in a manner that avoids substantial contact between the oxygen and the briquettes, thereby creating a quiescent zone immediately above the briquettes, with the quiescent zone being sufficient to minimize reoxidation of the reduced briquettes, and minimize entrainment of particulate matter from the briquettes.

A process for treating agglomerating coal includes providing dried, pulverized, agglomerating coal, and treating the coal in a vessel with a gas stream having an oxygen content sufficient to form at least some oxides on surface of coal particles, wherein the oxides are sufficient to convert coal into substantially non-agglomerating coal. The treated coal is transferred into a pyrolyzing chamber and passed into contact with an oxygen deficient sweep gas, the sweep gas being at a higher temperature than the temperature of the coal so that heat is supplied to the coal. The process further includes providing additional heat to coal indirectly by heating the chamber, wherein the heating of coal by the sweep gas and by the indirect heating from the chamber causes condensable volatile components to be released into the sweep gas. The sweep gas is removed from the chamber and treated to remove condensable components of coal.

A process for treating bituminous coal includes providing dried, pulverized coal, and treating the pulverized coal in a vessel with a gas stream having an oxygen content sufficient to form oxides on surface of coal particles. The treated coal is transferred into a pyrolyzing chamber and passed into contact with an oxygen deficient sweep gas, the sweep gas being at a higher temperature than the temperature of the coal so that heat is supplied to the coal. The process further includes providing additional heat to the coal indirectly by heating the chamber, wherein the heating of coal by the sweep gas and by the indirect heating from the chamber causes condensable volatile components to be released into the sweep gas. Some of the oxides are converted into paramagnetic mineral components, which are removed from coal to form a coal char having reduced ash and sulfur.

A process for treating coal includes introducing coal into a chamber and passing an oxygen deficient sweep gas into contact with the coal, the sweep gas being at a higher temperature than the temperature of the coal so that heat is supplied to the coal. The process further includes providing additional heat to the coal indirectly by heating the chamber, wherein the heating of the coal by the sweep gas and by the indirect heating from the chamber causes condensable volatile components to be released into the sweep gas. The proportion of heat supplied to the coal by the sweep gas is less than 40% of the total heat supplied to the coal. The sweep gas is then removed from the chamber and treated to remove condensable components of the coal.

A process for treating input coal includes treating input coal in a pyrolysis step to form coal char. The pyrolysis step includes heating the coal substantially in the absence of oxygen to remove volatile material from the coal. The volatile material evolved from the coal in the pyrolysis step is treated to separate the volatile material into gases and liquids, wherein the liquids contain condensed volatile material. A portion of the liquids is directed to the coal char, and the returned portion of the liquids is mixed with the coal char, thereby returning some of the volatile material to the coal char.

A process for treating agglomerating coal includes drying coal in a drying step, and treating the dried coal in an oxidizing step to form oxides sufficient to convert the coal into a substantially non-agglomerating coal. The oxidized coal is pyrolyzed in a pyrolysis step to form coal char, and the coal char is cooled. At least one of the drying, oxidizing, and pyrolyzing steps is a dual zone step, with the dual zone step having a first zone and a second zone, with the temperature of the second zone being higher than that of the first zone.
