摘要： A method and apparatus are provided to control the burning of a lean hydrocarbon containing gas stream under stable conditions using a combination of control logic and hardware. Temperature within the combustor is controlled by using a plurality of staging valves that adjust the amount of oxygen and auxiliary fuel supplied to the combustor burner. Oxygen level is controlled by using actuated butterfly valves that control the flow of primary air to the combustor. The system has pressure control valves for anticipating and compensating for pressure changes and resulting air flow changes as well as temperature monitors and transmitters for anticipating and correcting temperature drops.

摘要： A process for recovering iron from iron-bearing materials including steel mill waste and iron-bearing ores. The process includes the steps of combining the iron-bearing materials, having metal oxides including iron oxides therein, with carbonaceous material to form a dry mixture. The dry mixture is agglomerated under conditions sufficient to mobilize volatile matter from the carbonaceous material to function as a binder and bond the dry mixture and form green compacts. The green compacts are then loaded into a preheated rotary hearth furnace void of compacts to form a layer of compacts no more than about two compacts high. The green compacts are heated for about 5 to 12 minutes at a temperature of between about 2150.degree. F. to 2350.degree. F. to reduce the compacts and evolve undesirable oxides from the compacts. The reduced compacts are then discharged from the rotary hearth furnace whereupon they are soaked to provide additional time for reaction to achieve 99% or more reduction of the iron oxides. The metallized iron compacts may then be cooled or transported hot to a steel making operation.

摘要： Method and apparatus is disclosed for thermally decomposing waste material from several batch furnaces plumbed into one afterburner. The afterburner is modified to mix and combust in a controlled manner an otherwise explosive mixture of fumes from several furnaces. The entire system is regulated only by the temperature of incinerated gases from the afterburner. The furnaces are operated in a sequenced, overlapping staged manner to produce a generally constant fume loading permitting significant cost savings in equipment and operation.

摘要： 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.

摘要： 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.

摘要： A continuous process for treating a noncaking coal to form stable char. The process includes the sequential steps of drying the coal to remove moisture therefrom and form a dry coal; pyrolyzing the dry coal by progressively heating substantially all of the coal to a temperature sufficient to vaporize and remove low end volatile materials from the coal to form char and sufficient to mobilize at least a portion of high end volatile materials within the char and at least partially collapse micropores within the char. The char is then cooled to a temperature sufficient to demobilize the volatile materials within the at least partially collapsed micropores of the char to pyrolytically passivate the char. The char is then conveyed to a reaction vessel wherein a process gas having about 3%-21% by volume oxygen flows through the reaction vessel to oxidatively passivate the coal by chemisorption of oxygen. The oxidatively passivated char is then substantially simultaneously rehydrated and cooled to form a char having about 5-10 wt % moisture and then conveyed to a final passivation vessel wherein a process gas having about 3%-21% by volume oxygen flows through the vessel to finally passivate the rehydrated char by chemisorption of oxygen.
