Abstract

The parent patent no. 2943309 described a method of producing gas from the combustion of refuse and coal, specially coal waste where the pyrolysis gas is passed to a second stage in which the pyrolysis coke is gasified. This coke is pref. passed through crushers before it is fed to the pyrolysis coke reactor. The lean gas from the latter is used for indirect heating in the first stage or is mixed with the rich pyrolysis gas. This makes the pyrolysis gas available for a town gas grid system after it has been purified.

"Gasherstellung aus Müll und Kohle bzw. Abfallkohle Zusatz zu P 29 43 309.8 In der Hauptanmeldung wird eine Verfahrenskombinatiön beschrieben, wobei in der ersten Verfahrensstufe eine Pyrolyse abläuft, und das dabei gewonnene Pyrolyse-Koksprodukt einer Vergasungsreaktorstufe zugeführt wird, und das Pyro-Gas der ersten Stufe in die zweite Stufe übernommen wird."Gas production from garbage and coal or waste coal Addition to P 29 43 309.8 In the main application, a combination of processes is described, with pyrolysis takes place in the first process stage, and the pyrolysis coke product obtained in the process a gasification reactor stage is fed, and the pyro gas of the first stage in the second stage is adopted.

Erfindungsgemäß wird hierzu erweiternd ausgeführt, daß das Pyro-Gas der ersten Stufe gereinigt wird und z.B.According to the invention, this is extended to the fact that the pyro gas the first stage is cleaned and e.g.

einem Stadtgasnetz zur Verfügung steht und die indirekte Beheizung des Pyro-Prozesses mit dem Schwachgas des Pyrokoksreaktors durchgeführt wird.a town gas network is available and indirect heating of the pyro process is carried out with the lean gas from the pyrocoke reactor.

Weiterhin wird erfindungsgemäß vorgeschlagen, je nach Anfall des Schwachgases im Pyrokoksreaktor, dieses Schwachgas zu reinigen und dem hochwertigen Pyro-Gas nach Bedarf zuzumischen.Furthermore, it is proposed according to the invention, depending on the amount of lean gas in the pyrocoke reactor to clean this lean gas and the high-quality pyro gas to be mixed in as required.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Verfahrensschritte begrenzt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, daß das Pyro-Gas gereinigt einem oder mehreren Verwendungszwecken zugeführt werden kann, und der im Pyro-Prozeß anfallende Pyrokoks einer direkt nachgeschalteten Feststoffvergaserstufe zugeführt wird, und das daraus entstandene Schwachgas zu indirekten Aufheizung der ersten Pyro-Prozeßstufe genutzt wird und/oder zum Verschneiden mit dem Pyro-Gas Anwendung finden kann.Of course, the invention is not limited to the above in detail described process steps limited, but numerous Modifications are possible without, however, deviating from the basic idea that the pyro gas cleaned can be supplied to one or more uses, and the Pyrocoke obtained in the pyro process from a solid gasification stage directly downstream is supplied, and the resulting lean gas to indirect heating of the first pyro process stage is used and / or for blending with the pyro gas Can apply.

In der beiliegenden Zeichnung ist das Verfahren dargestellt mit (1) der Pyro-Prozeß mit (2) der wärmeverlustfreie Übergang des Pyrokokses aus der Pyrolyse-Anlage (1) in den Pyrokoksvergasungsreaktor (2) dazwischen liegend kann ein Heißgasbrecher angeordnet sein (3) mit (4) wird das Pyro-Gas direkt aus der Innentrommel einer Gasreinigungsanlage (5) zugeführt. In the accompanying drawing, the process is shown with (1) the pyro process with (2) the heat loss-free transition of the pyrocoke from the pyrolysis plant (1) A hot gas breaker can be placed in between the pyrocoke gasification reactor (2) be arranged (3) with (4) is the pyro gas directly from the inner drum of a Gas cleaning system (5) supplied.
