Abstract

A fuel is prepd. from waste and coal by first freeing the waste from the most important harmful substances causing emissions, and then mixing the very moist remaining material with very finely ground dried coal (less than 1% water), and opt. with coarser coal (0-10mm), with cpds. to prevent fermentation and to improve the storability, and with additives to reduce flue gas emissions, esp. acid harmful gases.

Description

Stand der TechnikState of the art

Es ist bekannt, daß sich die Verbrennungseigen­ schaften von Müll durch Vermischen mit Kohle verbessern lassen. Allerdings hat sich dieses Verfahren wegen der erforderlichen vorbereitenden Müllbehandlung nicht am Markt durchgesetzt. Alle Vorbehandlungen haben dabei einen möglichst hohen und gleichmäßigen Heizwert zum Ziel, ohne daß die müllspezifischen Emissionen direkt beeinflußt werden.It is known that the combustion properties create waste by mixing it with coal let it improve. However, this has Procedure due to the necessary preparatory Waste treatment not enforced on the market. All Pretreatments have the highest possible and even calorific value to the goal without the garbage-specific emissions directly influenced will.

VerfahrensbeschreibungProcess description

Erfindungsgemäß wird daher vorgeschlagen, dem Müll durch eine hochwertige Aufbereitungstechnik nach der Metallabscheidung die wesentlichen, emissions­ relevanten Komponenten wie z. B. Papier und Kunst­ stoffe zu entziehen und nur die organische Fraktion (z. B. Grünabfälle) sowie die Reststoffe (vorwiegend mineralischen Ursprungs) als sogenannten Weichstoff für den Verbrennungsprozeß zur Verfügung zu stel­ len. According to the invention, it is therefore proposed that the waste through high-quality processing technology the essential, emissions relevant components such as B. Paper and art withdraw substances and only the organic fraction (e.g. green waste) and residues (predominantly mineral origin) as a so-called soft substance available for the combustion process len.  

Um den hohen Feuchtigkeitsgehalt dieses Weichstof­ fes abzusenken und eine stabile Verbrennung zu ge­ währleisten, wird das Material auf eine Korngröße von 0 bis etwa 10 mm zerkleinert und mit feinst aufgemahlener Kohle, die auf weniger als 3% H2O getrocknet ist, vermischt. Zur einfachen Handhabung dieses Gemischs muß sich eine Kompaktierung an­ schließen. Es ist deshalb erforderlich, zusätzlich ein Stützgerüst aus Feinkohle, ebenfalls 0 bis etwa 10 mm, der Mischung zuzugeben. Damit ferner trotz des Kompaktierens keine beeinträchtigenden Gärungs­ prozesse auftreten, werden geeignete Chemikalien zudosiert.In order to lower the high moisture content of this soft substance and to ensure stable combustion, the material is crushed to a grain size of 0 to about 10 mm and mixed with finely ground coal that has dried to less than 3% H 2 O. For easy handling of this mixture, a compacting must follow. It is therefore necessary to add a fine carbon support frame, also 0 to about 10 mm, to the mixture. Suitable chemicals are metered in so that no adverse fermentation processes occur despite the compacting.

Zur weiteren Absenkung der Emissionen können zu­ sätzlich Additive hinzugefügt werden, die den Ausstoß insbesondere der sauren Schadgase nach­ haltig reduzieren.To further reduce emissions, too additional additives are added which Emissions especially of acidic harmful gases reduce permanently.
