Description

Die Erfindung betrifft ein Verfahren gemäß Oberbegriff des Anspruches 1.The invention relates to a method according to the preamble of claim 1.

Gemäß Patent 29 43 309 werden Kohle und Müll gemeinsam nach entsprechender Vorbereitung pyrolisiert und anschließend weiterverarbeitet. Als zusätzlicher Kohlenstoffträger wird vorzugsweise unvorbehandelte Ballastkohle eingesetzt, die dem Müll vor der Pyrolyse zugesetzt wird, um eine Mischung mit homogenisiertem Heizwert zu erhalten. Die Pyrolyse läuft dann ab, wobei die Mischung durch Änderung der Fließ- und Förder­ richtung intensiv durchmengt wird. Als Weiterbehandlung ist dann vorgesehen, daß die festen Pyrolyseprodukte unter Zufuhr des Pyrolysegases und von Luft- und Wasserdampf anschließend vergast werden.According to patent 29 43 309, coal and waste are common after appropriate preparation pyrolyzed and then processed further. As an additional carbon carrier preferably untreated ballast coal, which the Garbage is added to a mixture before pyrolysis to get a homogenized calorific value. The pyrolysis then runs starting with the mixture by changing the flow and delivery direction is intensely mixed. As further treatment is then provided that the solid pyrolysis products be fed of the pyrolysis gas and of air and water vapor subsequently be gassed.

Der Erfindung liegt nun die Aufgabe zugrunde, in der Vergasung auch andere Weiterverarbeitungsmöglichkeiten für die die Pyrolysestufe verlassenden Produkte zu finden.The invention is based on the object in Gasification also other processing options for the to find products leaving the pyrolysis stage.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daßThe object is achieved in that

  • 1. Müll und Ballastkohle pyrolisiert werden,1. waste and ballast coal are pyrolyzed,
  • 2. daß die festen Pyrolyseprodukte dann unter möglichst weit­ gehender Ausschaltung von Wärmeverlusten auf eine für die Beschickung eines Brenners geeignete Korngröße zerkleinert werden,2. that the solid pyrolysis products then as far as possible switching off heat losses to one for the Feeding a burner crushed suitable grain size will,
  • 3. daß die zerkleinerten Pyrolyseprodukte einem Kohlebrenner zugeführt und unter einem Kraftwerkskessel verbrannt werden und3. that the crushed pyrolysis products a coal burner fed and burned under a power plant boiler and
  • 4. daß die Pyrolysegase in einem Gasbrenner ebenfalls in dem Kraftwerkskessel verbrannt werden.4. that the pyrolysis gases in a gas burner also in the Power plant boilers are burned.

Damit ist ein Verfahren geschaffen, bei dem das entstehende Pyrolysegas ohne Vorreinigung der Energienutzung im normalen Kohlekraftwerkskessel zugeführt werden kann, wobei gleich­ zeitig eine vorteilhafte Verarbeitung der festen Pyrolyse­ produkte gegeben ist. Aufgrund der vollständigen Wärmenutzung in der nachgeschalteten Kraftwerkskesselanlage ergibt sich ein wirtschaftliches Gesamtverfahren. Ein solches Verfahren eignet sich insbesondere für kleinere ältere Kraftwerkskessel, indem einfach eine entsprechende Vorschaltstufe als Müll- Abfallkohle- oder als Müll-Kohle-Pyrolysestufe genutzt wird.This creates a process in which the resulting Pyrolysis gas without pre-cleaning energy use in normal  Coal-fired power plant boilers can be supplied, being the same early advantageous processing of solid pyrolysis products is given. Because of the full use of heat in the downstream power plant boiler system overall economic process. Such a process is particularly suitable for smaller older power plant boilers, by simply using a corresponding preliminary stage as Waste coal or as a waste-coal pyrolysis stage is used.

Anhand der Zeichnung wird das erfindungsgemäße Verfahren weiter erläutert. Der Müll und die Ballastkohle wird der Pyrolysestufe (1) zugeführt und dann ohne Wärmever­ lust im Kraftwerkskessel (3) weiterverarbeitet. Der die Pyrolysestufe (1) und den Kraftwerkskessel (3) verbindende Bereich ist mit (2) bezeichnet und so ausgeführt, daß dort Wärmeverluste weitgehend vermieden werden.The method according to the invention is further explained with the aid of the drawing. The garbage and ballast coal is fed to the pyrolysis stage ( 1 ) and then processed without loss of heat in the power plant boiler ( 3 ). The area connecting the pyrolysis stage ( 1 ) and the power plant boiler ( 3 ) is designated ( 2 ) and is designed in such a way that heat losses are largely avoided there.

Im Bereich (2) ist eine Zerkleinerungseinrichtung (4) untergebracht, in der der heiße Pyrolysekoks aufgemahlen wird. Der die Zerkleinerungseinrichtung (4) verlassende Pyrolysekoks hat dann eine Korngröße, die eine Weiterverarbeitung in Kohle­ brenner (6) ermöglicht, wobei über den Gasbrenner (5) das in der Pyrolysestufe (1) anfallende Pyrolgas gleichzeitig mit­ verbrannt wird. Auf diese Weise ist es möglich, auch das Pyrolysegas nutzbar im Kraftwerkskessel (3) zu verarbeiten. Über die Zufuhreinrichtung (7) ist die Möglichkeit gegeben, der Zerkleinerungseinrichtung (4) aus einem hier nicht dar­ gestellten Bunker weitere Kohle und Koks zuzuführen, um so den Heizwert gezielt zu beeinflussen.A crushing device ( 4 ) is housed in area ( 2 ), in which the hot pyrolysis coke is ground. The pyrolysis coke leaving the comminution device ( 4 ) then has a grain size which enables further processing in coal burners ( 6 ), the pyrolegas obtained in the pyrolysis stage ( 1 ) being simultaneously burned with the gas burner ( 5 ). In this way, it is also possible to process the pyrolysis gas usably in the power plant boiler ( 3 ). Via the feed device ( 7 ) there is the possibility of feeding the comminution device ( 4 ) further coal and coke from a bunker (not shown here) in order to specifically influence the calorific value.
