Abstract
Description
Die Erfindung betrifft einen auf Querträgern gelagerten luftgekühlten Rostbelag, insbesondere für Vorschubroste bei Müllverbrennungsanlagen, wobei zwei nebeneinander angeordnete Roststäbe jeweils einen Strömungs kanal bilden, der durch den Roststabrücken und dessen stützende Stege begrenzt ist und durch im Roststabkopf angeordnete Ausnehmungen Auslaß zum Feuerraum hat.The invention relates to an air-cooled mounted on cross members Grate covering, especially for feed grates in waste incineration plants, whereby two grate bars arranged side by side each have a flow form channel through the Roststabrücken and its supporting webs is limited and outlet arranged in the grate rod head recesses to the firebox.
Ein derartiger Rostbelag, bei dem durch die spezielle Formgebung des Einzelroststabes und durch das Zusammenpacken zu einzelnen Roststab paketen eine gezielte Luftführung erreicht wird, ist durch die DE-PS 37 25 585 bekanntgeworden.Such a rust covering, in which the special shape of the Single grate bar and by packing together to single grate bar targeted air flow is achieved through the DE-PS 37 25 585 become known.
Nachteilig ist jedoch bei diesem bekannten Rostbelag, daß die Gleit fläche der Roststäbe, d. h. die Roststabrücken und Roststabfüße starkem Verschleiß durch Reibung ausgesetzt sind und dadurch die Roststäbe häufig ausgewechselt werden müssen.The disadvantage of this known grating that the sliding surface of the grate bars, d. H. the grate bars and grate bar feet strong Wear due to friction and thereby the grate bars need to be replaced frequently.
Aufgabe der Erfindung ist es, einen Rostbelag der eingangs beschriebenen Art so auszugestalten, daß die Standzeiten des Rostbelages wesentlich verlängert werden können.The object of the invention is a grate of the type described Art to design so that the service life of the grate is essential can be extended.
Diese Aufgabe wird durch den kennzeichnenden Teil des Patentanspruches gelöst.This object is achieved by the characterizing part of the claim solved.
Durch die erfindungsgemäße Ausgestaltung des Rostbelages werden die Standzeiten der einzelnen Roststäbe wesentlich verlängert, da eine optimale Werkstoffauswahl getroffen werden kann. Ein weiterer Vorteil ist die Einsparung von Material, da das anteilige Gewichtsverhältnis der Schleißplatten zum Roststab ca. 1 : 6 beträgt. Ferner sind die Schleißplatten leicht auszuwechseln und dementsprechend kann der Aufwand für die Instandsetzungsarbeiten niedrig gehalten werden.The inventive design of the grate covering The service life of the individual grate bars is significantly extended because of a optimal material selection can be made. Another advantage is the saving of material because of the proportionate weight ratio the wear plates to the grate bar is approx. 1: 6. Furthermore, the Wear plates can be easily replaced and accordingly Maintenance costs can be kept low.
Die Erfindung wird anhand der Beschreibung und der Zeichnung näher erläutert. Es zeigtThe invention will become more apparent from the description and the drawing explained. It shows
