Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von schadstoffbindenden Additiven für Brennstoffe, z. B. Kohle.The invention relates to a method of manufacture of pollutant-binding additives for fuels, e.g. B. Coal.

Derartige Brennstoffe dienen zur Einbindung von in Brenn­ stoffen vorhandenen sauren und anderen Schadstoffen während der Verbrennung in Verbrennungsanlagen. Sie werden dem Brennstoff üblicherweise aus Silos oder Vorlagebunkern dosiert zugeführt.Such fuels are used for the integration of in fuel substances present acidic and other pollutants during combustion in incineration plants. They will Fuel usually from silos or storage bunkers dosed fed.

Um eine ordnungsgemäße Additivzugabe aus den Silos oder Vorlagebunkern zu gewährleisten, ist eine Beheizung der die Additive enthaltenden Silos und Vorlagebunker, insbe­ sondere in den Wintermonaten, unumgänglich. Darüber hinaus müssen Maßnahmen getroffen werden, um sicherzustellen, daß die Förderluft weitestgehend getrocknet ist, um zu ver­ hindern, daß sich Kondenswasser bildet, was zu einem Klumpen des häufig kalkhaltigen Additivs führen würde, woraus sich erhebliche Störungen bei der Förderung des Additivs und damit bei der Dosierung und Zugabe des Additivs zu dem Brennstoff ergeben würden. Die herkömmlicherweise zur Ver­ hinderung der vorstehend aufgeführten nachteiligen Wirkungen durchgeführten Maßnahmen sind mit einem nicht unerheblichen Kostenaufwand verbunden.For proper additive addition from the silos or To ensure storage bunkers is heating the the additives containing silos and storage bunkers, esp especially in the winter months, essential. Furthermore measures must be taken to ensure that the conveying air is largely dried to ver prevent condensation from forming, resulting in a lump of the often calcareous additive would result in  significant disruptions in the conveyance of the additive and thus when dosing and adding the additive to the Would result in fuel. The conventionally used for ver preventing the adverse effects listed above implemented measures are with a not insignificant Associated costs.

Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße Verfahren zur Herstellung von schadstoffbindenden Additiven für Brennstoffe derart weiterzubilden, daß in wesentlich einfacherer und kostengünstigerer Weise ein ordnungsgemäßes Förderverhalten des Additivs gewährleistet ist.The invention has for its object the generic Process for the preparation of pollutant-binding additives for fuels in such a way that in essential a proper, easier, and cheaper way Delivery behavior of the additive is guaranteed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Additive so stark mit hydrophoben Stoffen gemischt werden, daß sie staubfrei förderfähig, nicht backfähig und nicht gefrierfähig sind. Hierdurch können derartige Additive in Silos oder Vorlagebunkern gelagert werden, ohne daß aufwendige Maßnahmen zur Beheizung der Silos oder Vorlagebunker bzw. zur Trockenhaltung der Förderluft ge­ troffen werden müßten. Der Austrag der Additive kann mit bekannten Fördereinrichtungen, z. B. Kratzbandförderern, Schneckenförderern, Stößeln o. dgl. erfolgen. In jedem Fall ist eine störungsfreie Zugabe und Zudosierung des Additivs zum Brennstoff gewährleistet. This object is achieved in that the additives mixed so strongly with hydrophobic substances be dust-free, not baked and are not freezable. This allows such Additives are stored in silos or storage bunkers, without complex measures for heating the silos or Storage bunker or to keep the conveying air dry should be hit. The additives can be discharged with known conveyors, e.g. B. scraper belt conveyors, Screw conveyors, plungers or the like. In any case is a trouble-free addition and metering of the additive guaranteed to fuel.  

In besonders vorteilhafter Weise lassen sich als hydrophobe Stoffe Bleicherde, Öle oder dergleichen einsetzen.In a particularly advantageous manner, they can be considered hydrophobic Use substances such as bleaching earth, oils or the like.

Aus der gemäß Patentgesetz 1981, § 3, Abs. 2, zum Stand der Technik gehörenden DE 40 05 782 A ist ein Verfahren bekannt, bei dem einen bei der Verbrennung fossiler Brenn­ stoffe eingesetzten Additiv Bleicherde beigemischt wird, jedoch spielt bei diesem bekannten Verfahren die Hydrophobie der Bleicherde keinerlei Rolle. Auch hinsichtlich der Dosiermenge der Bleicherde werden in der genannten Druck­ schrift keine Angaben gemacht.From the status according to Patent Law 1981, § 3, Paragraph 2 DE 40 05 782 A belonging to the technology is a method known in the one when burning fossil fuel bleaching earth additive is added, however, hydrophobicity plays a role in this known method the bleaching earth doesn't matter. Also regarding the Dosing amount of the bleaching earth are in the mentioned pressure no information given.

Im folgenden werden die im Zusammenhang mit der Erfindung einhergehenden Vorteile an Hand der einzigen Figur er­ läutert.The following are those related to the invention associated benefits based on the single figure he purifies.

Aus einem Brennstoffbunker 1 wird über eine Brennstoffzu­ führung 4 Brennstoff aus dem Brennstoffbunker 1 in eine Verbrennungsanlage 2 geführt. An der Brennstoffzuführung 4 ist eine Additivzuführung 5 angeordnet, an der aus einem offenen oder geschlossenen Bunker oder Silo 3 stammendes Additiv dem Brennstoff beigegeben wird.From a fuel bunker 1 , fuel is fed from the fuel bunker 1 into a combustion system 2 via a fuel feed 4 . An additive feed 5 is arranged on the fuel feed 4 , on which additive originating from an open or closed bunker or silo 3 is added to the fuel.

Von besonderem Vorteil ist das erfindungsgemäß hergestellte Additiv beim Einsatz von Transportsilos, die sowohl zum Transport als auch zur Abgabe des Additivs geeignet sind und die bei Entleerung ausgetauscht werden können.The one produced according to the invention is particularly advantageous  Additive when using transport silos, both for Transport as well as the delivery of the additive are suitable and which can be replaced when emptied.
