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： 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.

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.

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.

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.
