Isolierkörper zum Einfügen in das Türblatt einer KesseltürInsulating body for insertion into the door leaf of a boiler door
Der Isolierkörper im Türblatt einer Kesseltür schützt diese gegen die hohen Feuerraumtemperaturen. Dafür sind solche Materialien geeignet, die den hohen Temperaturen standhalten und eine wärmedämmende Wirkung besitzen. Neben Keramikkörpern sind auch Einsätze aus Fasermaterialien gebräuchlich. Als geeignet haben sich Mineralfasereinsätze erwiesen, insbesondere sind Mineralfaserprodukte mit erhöhter physiologischer Abbaubarkeit vorteilhaft einsetzbar. Bei der Anwendung dieser Faserprodukte sollte aber darauf geachtet werden, daß ein Abtrag feinster Partikel und Bestandteile von der Oberfläche mechanisch durch den Rauchgasstrom und/oder chemisch durch korrosive Abgasbestandteile vermieden wird.The insulating body in the door leaf of a boiler door protects it against the high combustion chamber temperatures. Materials that can withstand the high temperatures and have a heat-insulating effect are suitable for this purpose. In addition to ceramic bodies, inserts made of fiber materials are also common. Mineral fiber inserts have proven to be suitable, in particular mineral fiber products with increased physiological degradability can be used advantageously. When using these fiber products, however, care should be taken to avoid the removal of the finest particles and components from the surface mechanically by the flue gas flow and/or chemically by corrosive exhaust gas components.
Der Neuerung liegt deshalb die Aufgabe zugrunde, einen Einsatz aus Fasermaterial, vorzugsweise aus Mineralfasern, zu schaffen, der gegen einen Abtrag von der Oberfläche resistent ist.The innovation is therefore based on the task of creating an insert made of fibre material, preferably mineral fibres, which is resistant to erosion of the surface.
Der neuerungsgemäße Isolierkörper ist gekennzeichnet durch eine insbesondere auf der Feuerraumseite des Einsatzes aufgebrachte Beschichtungsmasse zur Erzeugung eines weitestgehend geschlossenen Überzuges.The new insulating body is characterized by a coating compound applied in particular to the combustion chamber side of the insert to produce a largely closed coating.
Ein solcher Überzug nach Art einer Imprägnierung gibt dem Isolierkörper eine weitestgehend geschlossene Oberfläche. Alle Vorzüge des Faserkörpers wie hohe Wärmedämmung und Temperaturwechselbeständigkeit bleiben erhalten. Neben der Verbesserung der mechanischen und chemischen Stabilität kann über die Auswahl geeigneter Binder und Füller die thermische Alterung, insbesondere die Bildung unerwünschter Rekristallisationsprodukte der Fasern bei hoher thermischer Beanspruchung unterdrückt werden.Such a coating, similar to an impregnation, gives the insulating body a largely closed surface. All the advantages of the fiber body, such as high thermal insulation and resistance to temperature changes, are retained. In addition to improving mechanical and chemical stability, thermal aging, in particular the formation of undesirable recrystallization products of the fibers under high thermal stress, can be suppressed by selecting suitable binders and fillers.
Die Beschichtungsmasse kann durch eine geeignetes Verfahren wie Spritzen, Streichen oder Tauchen aufgebracht werden. Dabei sollte die Konsistenz im noch nicht ausgehärteten Zustand so sein, daß die Masse in die faserige Oberfläche hineindiffundiert und nach außen einen weitestgehend geschlossenen Überzug bildet.The coating compound can be applied using a suitable method such as spraying, brushing or dipping. The consistency in the uncured state should be such that the compound diffuses into the fibrous surface and forms a largely closed coating on the outside.
Als Beschichtungsmassen sind flüssige Feuerfestbinder, etwa auf der Basis eines kolloidalen Aluminiumoxids zu verwenden. Beigemischte FülleV aus Kornfraktionen von säurestabilen und/oder gegebenenfalls basenstabilen chemischen Verbindungen mit geeigneter thermischer Beständigkeit bewirken die Abdeckung und Verdichtung des Faserkörpers von der Oberfläche her.Liquid refractory binders, such as those based on colloidal aluminum oxide, are to be used as coating materials. Added fillers made of grain fractions of acid-stable and/or possibly base-stable chemical compounds with suitable thermal resistance cover and compact the fiber body from the surface.
Durch zusätzlich beigemischte organische Verdicker kann gegebenenfalls die Verarbeitbarkeit der Beschichtungsmasse eingestellt und dem Auftragsverfahren angepaßt werden.By adding additional organic thickeners, the processability of the coating mass can be adjusted and adapted to the application process.
Die Zeichnung stellt ein Ausführungsbeispiel der Neuerung dar. Es zeigt:The drawing shows an example of the innovation. It shows:
Fig. 1: Einen vertikalen Schnitt durch eine Kesseltür undFig. 1: A vertical section through a boiler door and
Fig. 2: Die vergrößerte Position X aus Fig. 1.Fig. 2: The enlarged position X from Fig. 1.
Im Türblatt der Kesseltür sitzt ein Einsatz 2 aus Fasermaterial, der das Türblatt gegen die hohen Temperaturen vom Feuerraum her abschirmt. Als Mittel gegen einen Materialabtrag ist ein die Oberfläche weitestgehend abdeckender und verschließender Überzug 3 zumindest auf der Feuerraumseite aufgebracht. Dieser besteht aus einer Beschichtungsmasse, die beim Auftrag in das faserige Material hineindiffundiert, aushärtet und mit dem Einsatz eine Einheit bildet.An insert 2 made of fiber material is located in the door leaf of the boiler door, which shields the door leaf against the high temperatures from the combustion chamber. As a means of preventing material erosion, a coating 3 that largely covers and seals the surface is applied at least on the combustion chamber side. This consists of a coating compound that diffuses into the fibrous material when applied, hardens and forms a unit with the insert.
