    Abstract: Beim Schmelzen von Glas aus Beschickungsgut (12) in Wannenöfen (1) mit Brennern (11) und mit Regeneratoren (6) für die Wiedergewinnung von Abwärme werden im Bereich der Flammenwurzeln Sauerstoff und Primärbrennstoffe zur Deckung des Wärmebedarfs für den Schmelzprozeß bei schwach unterstöchiometrischen Bedingungen zugeführt. Zur weiteren Reduzierung der Gehalte an NO x und CO in den Abgasen durch Nachverbrennung bzw. Nachoxidation jenseits der Flammenenden werden Sekundärbrennstoffe und stromabwärts weitere Luft zugeführt, um durch den Sekundärbrennstoff in oder über der Kammergitterung (5a, 6a) NO x zu reduzieren und stromabwärt durch die Luftzufuhr eine Nachverbrennung bzw. Nachoxidation durchzuführen, so daß schließlich eine zumindest weitgehend stöchiometrische Verbrennung erfolgt. Die Abgase werden vor dem Eintritt in einen Abgaskamin (15) zur Vorwärmung des Beschickungsguts (12) in mindestens einem Gutvorwärmer (13) verwendet. Um eine nahezu vollständige Rückgewinnung der Energieinhalte der Brennstoffe und einen kontinuierlichen Strom des Beschickungsguts zu gewährleisten, wird die Temperatur der aus den Regeneratoren (6) stammenden Abgase vor dem Eintritt in den mindestens einen Gutvorwärmer (13) gemessen, und die Menge der Sekundärbrennstoffe wird in Abhängigkeit von den gemessenen Temperaturwerten geregelt.

    Abstract: A system and process are provided for converting a light hydrocarbon gas to a synthetic heavier hydrocarbon liquid. The system includes an autothermal reformer, a Fischer-Tropsch reactor and a Brayton cycle that are structurally and functionally integrated. In the practice of the process, a mixture of a hydrocarbon feed gas, a compressed air feed and process steam is fed to the autothermal reformer to produce a synthesis gas. The synthesis gas is fed to the Fischer-Tropsch reactor where it is catalytically reacted to produce heavy hydrocarbons. The outlet from the Fischer-Tropsch reactor is separated into water, a low heating value tail gas, and the desired hydrocarbon liquid product. The water is pressurized and heated to generate process steam. The tail gas is heated and fed with compressed air and steam to the Brayton cycle having a combustor and a series of power turbines and compressors. The tail gas and air feed are burned in the combustor to produce a combustion gas that is used to drive a power turbine linked by a shaft to an air compressor, thereby driving the air compressor. The system further includes a plurality of heat exchangers that enable heat to be recovered from the outlet of the autothermal reformer. The recovered heat is used to make the process steam as well as to preheat the hydrocarbon feed gas before it is fed to the autothermal reformer, preheat the synthesis gas before it is fed to the Fischer-Tropsch reactor and preheat the tail gas before it is fed to the combustor.

    Inventor: Markstein, Josef

    Abstract: The present invention discloses a method of, and apparatus for, reducing NOx emissions from black coal fired updraught furnaces (20). The pulverised coal is entrapped in the "primary air" and separated into two streams, one fuel rich (13) and one fuel lean (15). These streams are introduced into the furnace (20) via a corresponding burner(s) (14,16) with the burner(s) (16) for the fuel lean stream (15) being located at an elevation above the burner(s) (14) for the fuel rich stream (13). The apparatus comprises a concentrator (3) positioned between the substantially conventional mill (1) and furnace (20) and arranged to split the primary air and entrapped fuel into the two abovementioned streams. The concentrator preferably includes a classifier (8) and takes the form of a swirl generator (5) and radially positioned outlets which make use of the action of centrifugal force on the "primary air" and entrapped coal particles to bring about the desired separation.
