Definitions
- the invention relates to a melting furnace for residues from waste incineration plants, in particular filter dust melting furnace, which is an existing substructure and superstructure
- the furnace contains the inside with a lining made of refractory material is lined.
- a melting furnace of this type is in the company publication "Die thermal treatment of residues according to the DEGLOR process " ABB W + E sawtechnik, CH-8048 Zurich, undated, described.
- the invention is based, bricks for specify such melting furnaces that have long service lives.
- a melting furnace with such a different composition of the lining in the melting area and in the furnace superstructure has a surprisingly long service life. It is essential that the brick lining in the furnace superstructure, that is to say in the gas atmosphere, contains no or as little Cr 2 O 3 as possible, since chromium can form toxic compounds with substances in the gas atmosphere. The best results were provided by masonry bricks made of pure MgO.

Description
Die Erfindung bezieht sich auf einen Schmelzofen für Reststoffe aus Müllverbrennungsanlagen, insbesondere Filterstaub-Schmelzofen, welcher ein aus Unterbau und Oberbau bestehendes Ofengefäss umfasst, das innen mit einer Ausmauerung aus Feuerfestmaterial ausgekleidet ist.The invention relates to a melting furnace for residues from waste incineration plants, in particular filter dust melting furnace, which is an existing substructure and superstructure The furnace contains the inside with a lining made of refractory material is lined.
Eine Schmelzofen dieser Gattung ist in der Firmenschrift "Die thermische Reststoffbehandlung nach dem DEGLOR-Verfahren" der Firma ABB W+E Umwelttechnik, CH-8048 Zürich, undatiert, beschrieben.A melting furnace of this type is in the company publication "Die thermal treatment of residues according to the DEGLOR process " ABB W + E Umwelttechnik, CH-8048 Zurich, undated, described.
Beim DEGLOR-Verfahren (DEGLOR ist eine eingetragene Marke der Firma W+E Umwelttechnik AG, CH-8048 Zürich) werden Filterstaub und Kesselasche ohne Zuschlagstoffe in einem elektrisch beheizten Schmelzofen bei Temperaturen um 1300 °C behandelt. Die Reststoffe schmelzen und werden über einen gasdichten Siphon aus dem Ofen ausgetragen und dann abgekühlt. Dabei entsteht ein problemlos deponierbarer glasartiger Rückstand. Während des Einschmelzvorganges dampfen die meisten Schwermetallverbindungen ab. Organische Schadstoffe wie Dioxine oder Furane werden thermisch zerstört. Nicht abdampfende hochsiedende Metallverbindungen werden ähnlich wie Blei in Bleikristallglas in die Glasmatrix eingebunden. Ein dem Ofen nachgeschalteter Ventilator sorgt dafür, dass die abgedampften Komponenten aus dem Ofen abgesaugt werden. With the DEGLOR process (DEGLOR is a registered trademark of W + E Umwelttechnik AG, CH-8048 Zurich) filter dust and boiler ash without additives in an electrically heated Melting furnace treated at temperatures around 1300 ° C. The Residues melt and are removed via a gas-tight siphon Discharged from the oven and then cooled. This creates a glassy residue that can be easily deposited. While most heavy metal compounds vaporize during the melting process from. Organic pollutants such as dioxins or furans are thermally destroyed. Non-evaporating high-boiling metal compounds are similar to lead in lead crystal glass integrated into the glass matrix. A downstream of the oven Fan ensures that the evaporated components from be sucked out of the oven.
Sowohl die (Glas-)schmelze als auch die Gasatmosphäre in diesen Öfen ist wesentlich korrosiver als in herkömmlichen Glasöfen. Von entscheidender Bedeutung für die Lebensdauer und damit überhaupt für eine wirtschaftliche Anwendung dieses Verfahrens ist deshalb die Materialauswahl der Ausmauerung dieser Öfen. Both the (glass) melt and the gas atmosphere in it Ovens are much more corrosive than in conventional glass ovens. Crucial for life and therefore for an economic application of this method at all is therefore the material selection of the lining Ovens.
Der Erfindung liegt die Aufgabe zugrunde, Ausmauerungen für derartige Schmelzöfen anzugeben, die hohe Standzeiten aufweisen.The invention is based, bricks for specify such melting furnaces that have long service lives.
Diese Aufgabe wird erfindungsgemäss durch die in den
Patentansprüchen 1 und 2 definierten Merkmale gelöst.This object is achieved by the in the
Ein Schmelzofen mit einer derartigen unterschiedlichen Zusammensetzung der Ausmauerung im Schmelzbereich und im Ofenoberbau zeitigt überraschend hohe Standzeiten. Wesentlich dabei ist, dass die Ausmauerung im Ofenoberbau, also in der Gasatmosphäre, kein oder möglicht wenig Cr2O3 enthält, da Chrom toxische Verbindungen mit Substanzen in der Gasatmosphäre bilden kann. Beste Ergebnisse lieferten dabei Ausmauerungen aus Steinen, die aus reinem MgO bestehen.A melting furnace with such a different composition of the lining in the melting area and in the furnace superstructure has a surprisingly long service life. It is essential that the brick lining in the furnace superstructure, that is to say in the gas atmosphere, contains no or as little Cr 2 O 3 as possible, since chromium can form toxic compounds with substances in the gas atmosphere. The best results were provided by masonry bricks made of pure MgO.
