Abstract

To generate gas and steam, a coal/refuse mixture or else only a refuse mixture is outgassed in an overfeed grate outgasser, the resulting gas is purified and the hot coke is either burnt directly or else cooled by heat exchange, discharged and stored. The heat recovered by the combustion of the coke or by the heat exchange is used for steam generation or for other energy-utilising purposes. A continuous operation is always ensured at all times, since the equipment for carrying out the process has an additional feed facility, through which coke can be fed if required. <IMAGE>

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

"Verfahren zur Erzeugung von Gas und Dampf über einen wahlweise vorgesetzten Gaserzeuger mit nachgeschalteter Verbrennungseinrichtung, die wahlweise auch als Wärmetauschereinrichtung genutzt werden kann"."Process for generating gas and steam via an optional superior Gas generator with a downstream combustion device, which can also be used as a Heat exchanger device can be used ".

In der Patentanmeldung 30 04 111.3 wird ein Verfahren beschrieben, in dem Kohle und Nbll gemischt wird, um a) unter entsprechender Temperatur Gas aus dem Gemisch zu gewinnen und b) den erzeugten Pyrokoks mit z.3. einer Temperatur von 6000C einem zweiten Reaktor zu übergeben, in dem der Koks zur Dampferzeugung bzw. Energiegewinnung in wunschgerechter Art verbrannt wird.In the patent application 30 04 111.3 a method is described, in which coal and Nbll is mixed to a) gas out at the appropriate temperature to win the mixture and b) the pyrocoke produced with z.3. a temperature of 6000C to be transferred to a second reactor in which the coke is used to generate steam or energy generation is burned in the desired manner.

Das Verfahren nach der Anmeldung P 30 04 111.3 ist gekennzeichnet durch eine Drehtrommel, in der die Entgasung durchgeführt wird und durch eine Wirbelbettfeuerungsanlage, in der der Koks verbrannt wird, Erfindungsgemsß wird nachstehend eine Vorrichtung beschrieben, die im 1. Teilbereich ein Kohle-Müll-Gemisch entgast. Im 2. Teilbereich wird das entgaste Produkt verbrannt und energetisch genutzt.The method according to application P 30 04 111.3 is marked through a rotating drum in which the Degassing is carried out and by a fluidized bed furnace in which the coke is burned, according to the invention a device is described below, which in the 1st part of a coal-garbage mixture degassed. In the second part, the degassed product is burned and used for energy.

In der beiliegenden Zeichnung ist die erfindungsgemäße Vorrichtung zur Durchführung der Kohle-Müll-Entgasung und anschließende Verbrennungsvorrichtung dargestellt: mit (1) Aufgabevorrichtung für das Gemisch aus Kohle und Müll; mit (2) der Gaserzeuger, der erfindungsgemäß als Überschub-Rost steuerbar in der Vorschubgeschwindigkeit angeordnet ist und bei (3) das erzeugte Gas aus dem K-ohle-Nüll-Produkt einem Gasreinigungssystem und/oder einem Gasverbrennungskessel zugeführt wird, wobei das Rückstandsprodukt bei (4) als Koks aus dem Gaserzeugerteil ausgeschleust wird und erfindungsgemäß mit voller Wärme gleichzeitig der Überschub-Rost-Feuerung (5) übergeben wird. Diese ist verzugsweise mit einem Dampferzeuger (6) gekoppelt, so daß die energetische Nutzung durchgeführt werden kann und bei (7) die umweltfreundliche, deponierbare Asche ausgetragen wird.In the accompanying drawing is the device according to the invention for carrying out the coal-waste degassing and subsequent incineration device shown: with (1) feeding device for the mixture of coal and garbage; with (2) the gas generator, which according to the invention can be controlled as an overfeed grate in terms of the feed speed is arranged and at (3) the gas generated from the K-ohle-Nüll product a gas cleaning system and / or one Gas combustion boiler is fed, with the residue product at (4) is discharged as coke from the gas generator part and according to the invention is transferred with full heat at the same time to the transfer grate furnace (5). These is preferably coupled to a steam generator (6), so that the energetic Use can be carried out and at (7) the environmentally friendly, landfillable Ashes are carried out.

Mit (8) ist die zusätzliche Einschleusvorrichtung dargestellt.With (8) the additional transfer device is shown.

Durch diese Kombieinheit, bestehend aus zwei gleichartigen Aggregaten, ist die Gewäht gegeben, daß der Müll auch allein oder aber vorzugsweise mit Kohle in der ersten Stufe entsprechend der Vorschub-Geschwindigkeit und der Schweltemperatur entgast werden kann und je nach notwendiger Gasmenge, z.B. 10 oder 20 %, z.B. zum Betreiben eines gasgefeurten kessels genutzt wird. Die Restenergie des hei@en Kokses kann z.B. erfindungsgemäß ohne Nachverbrennung im Überschub-Rost-System unter Abkühlung zur Fernwärmeerzeugung genutzt werden, so daß der abgekühlte Pyrokoks am Ascheaustrag z.B. in den Sommermonaten für die Bereiche der Energie erzeugung im Winter gelagert werden kann.With this combination unit, consisting of two similar units, it is given that the garbage can also be used alone or, preferably, with coal in the first stage according to the feed speed and the smoldering temperature can be degassed and depending on the required amount of gas, e.g. 10 or 20%, e.g. for Operation of a gas-fired boiler is used. The residual energy of the hot coke can e.g. according to the invention without afterburning in the transfer grate system be used under cooling for district heating, so that the cooled pyrocoke at the ash discharge e.g. in the summer months for the areas of energy generation can be stored in winter.

Das Verfahren ist also gekennzeichnet durch die totale energetische Nutzung a) Gas und n) Verbrennung von Koks zur Wärmenutzung oder Stromerzeugung - oder aber zur Gaserzeugung und Grundlast - Wärmeabgabe über die Abkühlung des erzeugten Kokses, wobei z.B. in den Wintermonaten der gelagerte Koks bei (4) zusätzlich zur Dampferzeugung genutzt werden kann. The process is characterized by the total energetic use of a) gas and n) combustion of coke for heat use or electricity generation - or for gas generation and base load - heat emission via the cooling of the coke produced, whereby e.g. in the winter months the stored coke at (4 ) can also be used to generate steam.
