Description

Die Erfindung betrifft einen Walzenrost zum Betrieb einer Verbrennungsanlage , insbesondere einer Müllverbrennung mit einem aus im Abstand achsparallel nebeneinander angeordneten rotierenden Walzen bestehenden Förderrost für das Verbrennungsgut, wobei die Walzen Gasdurchtrittsöffnungen zur Einleitung von Luft und/oder Gas in den Verbrennungsraum bzw. das Verbrennungsgut aufweisen und zwischen den benachbarten Walzen ein Zwischenraum eingehalten ist, in dem Abstreifer vorgesehen sind, die auf einem unterhalb des Zwischenraums angeordneten Abstreifträger befestigt sind. Die meist aus Schleißeisen bestehenden Abstreifer dienen zur Verhinderung bzw. Minimierung eines Durchrutschens von Verbrennungsgut durch die Zwischenräume zwischen den Walzen.The invention relates to a roller grate for operating an incinerator, in particular a refuse incineration with a paraxial distance juxtaposed rotating rollers existing conveyor grate for the Combustion material, wherein the rollers gas passage openings for the introduction of air and / or gas in the combustion chamber or the combustion material and have between the adjacent rollers, a gap is maintained, in the Scrapers are provided on one below the gap arranged Abstreifträger are attached. The most of existing Schlei iron Scrapers are used to prevent or minimize slippage of Combustion material through the spaces between the rollers.

Die Rostwalzen derartiger Walzenroste (DE 11 64 014, DE 3316 363) weisen einen aus Roststäben gebildeten Walzenmantel auf. Die Zuteilung der primären Verbrennungsluft erfolgt für jede Rostwalze separat über Luftzuführkanäle in die Aschetrichter, die unterhalb des Walzenrostes angeordnet sind. Die Verbrennungsluft strömt durch die Schlitze zwischen den Roststäben von unten durch den Walzenkörper und verlässt diesen an der Oberseite ebenfalls durch Schlitze zwischen den Roststäben. Zwischen den mit Abstand voneinander angeordneten Rostwalzen befinden sich Stauräume, in denen das Brenngut umgewälzt und mit Verbrennungsluft in Kontakt gebracht wird. In den Stauräumen angeordnete Abstreifer sorgen für Abreinigung der Roststäbe von Anhaftungen infolge Schlackenbildung. Derartige Abstreifer sind starr und können mit Bürsten versehen sein (EP 01 57 920).The grate rollers of such roller grates (DE 11 64 014, DE 3316 363) have a Roll shell formed from grate bars on. The allocation of the primary Combustion air takes place separately for each grate roller via air supply channels in the Ash hopper, which are located below the roller grate. The combustion air flows through the slots between the grate bars from below through the Roll body and leaves it at the top also through slots between the grate bars. Between the spaced apart Grate rollers are storage spaces in which the kiln is circulated and with Combustion air is brought into contact. Located in the storage spaces Scrapers provide for cleaning of the grate bars from buildup due to Slag formation. Such scrapers are rigid and can be provided with brushes be (EP 01 57 920).

Darüber hinaus sind auch Anlagen bekannt (DE 44 18 924) bei denen sich zwischen benachbarten Rollen Sperrelemente befinden, die ein Durchrutschen des Verbrennungsgutes nach unten verhindern bzw. minimieren. Die Außenkanten dieser Sperrelemente müssen einen gewissen Abstand zu den Rollenoberflächen aufweisen, wobei sie gleichzeitig als Abstreifer für an der Rollenoberfläche angebackenes Verbrennungsgut dienen können. In addition, facilities are known (DE 44 18 924) in which between adjacent rollers are locking elements that slip through the Prevent or minimize incineration downwards. The outer edges of this Barrier elements must be at a certain distance from the roller surfaces at the same time as a scraper for on the roller surface can serve baked goods.

Während des Betriebes und insbesondere beim Anfahren herrschen oberhalb (Feuerraumtemperatur) und unterhalb der Walzen (Primärlufttemperatur im Aschetrichter) stark unterschiedliche Temperaturen. Diese Temperaturdifferenz führt u.a. auch zu unterschiedlichen Temperaturen im Profil der Abstreifträger. Insbesondere führen die höheren Temperaturen im oberen Bereich (zum Feuerraum zugewandte Seite) zu einer thermischen Dehnung der Abstreifträger in Richtung Feuerraum. Dies kann im ungünstigsten Fall zu einer Berührung der Abstreifer mit den Walzen führen und das Drehen der Walzen behindern.During operation and in particular when starting prevail above (Furnace temperature) and below the rolls (primary air temperature in Ash funnel) strongly different temperatures. This temperature difference leads et al also at different temperatures in the profile of the Abstreifträger. In particular, the higher temperatures lead in the upper area (to the firebox facing side) to a thermal expansion of the Abstreifträger in the direction Firebox. This can in the worst case to contact the scraper with lead the rollers and hinder the rotation of the rollers.

Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, einen Walzenrost vorzustellen, der diese genannten Nachteile vermeidet und unzulässige thermische Dehnungen der Abstreifer und Abstreifträger verhindert bzw. derart reduziert, daß diesbezüglich keine Funktionsstörungen des Walzenrostes zu erwarten sind. Erfindungsgemäß wird diese Aufgabe durch die Merkmale der Ansprüche 1 und 5 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der jeweils zugehörigen Unteransprüche.The object of the present invention is therefore a roller grate to introduce, which avoids these mentioned disadvantages and inadmissible thermal Strains of the scraper and Abstreifträger prevented or reduced so that In this regard, no malfunction of the roller grate are to be expected. According to the invention this object is achieved by the features of claims 1 and 5 solved. Further advantageous embodiments of the invention are the subject of respectively associated subclaims.
