摘要： 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.

摘要： A screw having a field replaceable flight. The screw includes a barrel and a helical flighting that is removably attached to the barrel by a plurality of brackets. The helical flighting includes a plurality of segments, each segment includes first and second opposing faces having an opening extending there though and side edges. The segments are positioned side by side to generally cooperatively form the flighting of the screw. At least one face of each segment includes raised bosses. The raised bosses project perpendicularly outwardly from the face of the segment to form a pocket within which the bracket is received. The segments are removably attached to the barrel by inserting a segment forming part of the flighting within the pocket and then removably fastening the segment within the pocket.

摘要： 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. The effluent from such a dual zone pyrolyzer are subjected to a condensation process to separate the effluents into liquids and on-gases, and the on-gases are combined with other available gases to achieve a composition of blended on-gases having a specific heat of at least about 0.50 Btu/lb-° F. (2.013 kJ/Kg ° C.) at 1200° F. (649° C.) and recirculated into the pyrolyzer.

摘要： 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.

摘要： A process for treating iron-bearing material with a carbonaceous material to form a dry mixture, wherein the amount of carbonaceous material added exceeds the stoichiometric amount required to reduce the metal oxide to elemental metal. In one embodiment, the process also includes blending an organic binder with the dry mixture. The dry mixture is agglomerated to bond the dry mixture and form green compacts. The green compacts are loaded into a heated furnace and heated for about 5-12 minutes at a temperature of between about 2100.degree.-2500.degree. F. to reduce the iron oxide containing compacts to compacts containing elemental iron and an excess amount of carbonaceous material wherein the excess amount of carbonaceous material counteracts re-oxidation of the elemental iron. The reduced compacts are then discharged from the furnace.

摘要： According to this invention there is provided a process and apparatus for the ignition of a pilot burner in an inert atmosphere without substantially contaminating the inert atmosphere. The process includes the steps of providing a controlled amount of combustion air for a predetermined interval of time to the combustor then substantially simultaneously providing a controlled mixture of fuel and air to the pilot burner and to a flame generator. The controlled mixture of fuel and air to the flame generator is then periodically energized to produce a secondary flame. With the secondary flame the controlled mixture of fuel and air to the pilot burner and the combustion air is ignited to produce a pilot burner flame. The pilot burner flame is then used to ignited a mixture of main fuel and combustion air to produce a main burner flame. The main burner flame then is used to ignite a mixture of process derived fuel and combustion air to produce products of combustion for use as an inert gas in a heat treatment process.
