Die Erfindung betrifft eine mikroporöse Wärmdämmplatte aus gepreßter pulverförmiger hochdispersiver Kieselsäure, die insbesondere zum Auskleiden von Brennräumen von gas-, öl- oder elektrisch befeuerten Heizkesseln bestimmt ist, aber auch andere Anwendung finden kann.The invention relates to a microporous thermal insulation board made of pressed powdered highly disperse silica, which is particularly intended for lining combustion chambers of gas, oil or electrically fired boilers, but can also find other applications.
Zur Wärmedämmung in öl- oder gasbefeuerten Heizkesseln ist es bekannt, im Brennraum sogenannte mikroporöse Wännedämmplatten einzusetzen, welche sich dadurch auszeichnen, daß sie günstigere Wärmeleitkoeffizienten aufweisen als ruhende Luft. Daher kann man mit Hilfe derartiger Wärmedämmplatten extrem platzsparend und effizient thermisch isolieren.For thermal insulation in oil or gas-fired boilers, it is known to use so-called microporous thermal insulation panels in the combustion chamber, which are characterized by the fact that they have more favorable thermal conductivity coefficients than still air. Therefore, with the help of such thermal insulation panels, thermal insulation can be achieved in an extremely space-saving and efficient manner.
Um die mechanische Beanspruchung der Oberflächen derartiger Wärmedämmplatten zu reduzieren, ist es weiterhin bekannt, brennerseitig aus künstlichen Keramikfasern (in der Regel Aluminiumoxyd-, Aluminiumsilikat- und Calciumsilikat-Fasern) bestehende Platten vor den empfindlichen mikroporösen Wärmedämmplatten anzuordnen. Aufgrund neuerer Bestimmungen sind jedoch künstliche Mineralfasern, insbesondere Aluminiumoxyd-, Aluminiumsilikat- und Calciumsilikat-Fasern in Gefahrenklassen eingestuft, wodurch ein bereits vorhandener Trend verstärkt wird, derartige Fasern, wenn technisch möglich, nicht mehr zu verwenden.In order to reduce the mechanical stress on the surfaces of such thermal insulation panels, it is also known to arrange panels made of artificial ceramic fibers (usually aluminum oxide, aluminum silicate and calcium silicate fibers) in front of the sensitive microporous thermal insulation panels on the burner side. However, due to newer regulations, artificial mineral fibers, in particular aluminum oxide, aluminum silicate and calcium silicate fibers, are classified into hazard classes, which reinforces an already existing trend to no longer use such fibers if technically possible.
Der Erfindung liegt die Aufgabe zugrunde, aus gepreßter pulverförmiger hochdispersiver Kieselsäure bestehende mikroporöse Wännedämmplatten ohne Einsatz von Fasermaterial wirksam gegen mechanisch bedingte Beschädigungen ihrer Oberfläche im praktischen Betrieb zu schützen, ohne daß diese Wännedämmplatten in ihrer Wärmedämmfunktion im praktischen Einsatz spürbar beeinträchtigt werden.The invention is based on the object of effectively protecting microporous thermal insulation panels made of pressed powdered highly dispersed silica without the use of fiber material against mechanically caused damage to their surface in practical operation, without these thermal insulation panels being noticeably impaired in their thermal insulation function in practical use.
Diese Aufgabe wird erfindungsgemäß mit einer mikroporösen Wärmedämmplatte gelöst, welche die Merkmale des Anspruches 1 aufweist. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved according to the invention with a microporous thermal insulation board, which has the features of claim 1. Advantageous embodiments and further developments of the invention are the subject of the subclaims.
Erfindungsgemäß wird die aus gepreßter, hochdispersiver Kieselsäure, welche als Rohstoff in Pulverform vorliegt, bestehende Wärmedämmplatte einseitig, beidseitig oder allseitig mit einer hochtemperaturbeständigen Beschichtung versehen, welche wirksam mechanische Beschädigungen der Oberfläche der Wärmedämmplatte verhindert.According to the invention, the thermal insulation board consisting of pressed, highly dispersed silica, which is present as a raw material in powder form, is provided on one side, both sides or all sides with a high-temperature-resistant coating which effectively prevents mechanical damage to the surface of the thermal insulation board.
Beispielsweise hat die mikroporöse Wärmedämmplatte eine Temperaturbeständigkeit von bis zu 1100° C. Die erfindungsgemäß vorgesehene Beschichtung hat hingegen eine Temperaturbeständigkeit von wenigstens bis zu 1400 C, aber auch für höhere Temperaturen.For example, the microporous thermal insulation board has a temperature resistance of up to 1100° C. The coating provided according to the invention, on the other hand, has a temperature resistance of at least up to 1400 C, but also for higher temperatures.
Die derart beschichtete Wärmedämmplatte kann, je nach Bedarfsfall, einseitig oder beidseitig und auch an den umlaufenden Kanten beschichtet sein.The thermal insulation board coated in this way can, depending on requirements, be coated on one or both sides and also on the surrounding edges.
Beispielsweise und vorzugsweise besteht die Beschichtung aus einer hochtemperaturbeständigen Masse, welche durch Aufsprühen, Aufspachteln, Anstreichen mit einem Pinsel, einer Rolle etc. aber auch im Tauchverfahren, aufgetragen wird. Die Masse trocknet an der Luft und/oder in einer Brennkammer oder an einem sonstigen Einsatzort der Wärmedämmplatte aus und verschließt die poröse Oberfläche der Wärmedämmplatte, so daß diese vor mechanischer Abrasion, gegen Rußpartikel, Säureangriffe, Winderosion etc. geschützt ist.For example and preferably, the coating consists of a high-temperature-resistant mass, which is applied by spraying, troweling, painting with a brush, roller, etc., but also by dipping. The mass dries in the air and/or in a combustion chamber or at another location where the thermal insulation board is used and seals the porous surface of the thermal insulation board so that it is protected against mechanical abrasion, soot particles, acid attacks, wind erosion, etc.
Obwohl es bevorzugt ist, die erfindungsgemäßen Wärmedämmplatten einseitig, beidseitig oder rundum mit hochtemperaturbeständiger Beschichtungsmasse zu versehen und damit sozusagen gegen mechanische Beschädigungen zu versiegeln, kann man auch andere Versiegelungsmedien, z.B. wärmestabile Folien, Inconelbleche oder andere korrosions- und hochtemperaturfeste Stähle als Obeiflächenbeschichtungen und Oberflächenschutz verwenden.Although it is preferred to provide the thermal insulation panels according to the invention with a high-temperature-resistant coating compound on one side, both sides or all around and thus seal them against mechanical damage, other sealing media, e.g. heat-stable films, Inconel sheets or other corrosion- and high-temperature-resistant steels, can also be used as surface coatings and surface protection.
Die Erfindung besteht in der Kombination von mikroporösen Wärmedämmplatten mit hochtemperaturbeständigen Beschichtungen, beispielsweise Beschichtungsmassen, welche vorzugsweise, aber nicht ausschließlich, für Heizkesselauskleidungen bestimmt sind.The invention consists in the combination of microporous thermal insulation panels with high-temperature-resistant coatings, for example coating compounds, which are preferably, but not exclusively, intended for boiler linings.
Als Beschichtungsmassen sind beispielsweise chemisch-keramisch bindende Emulsionen, die an der Luft verfestigen, geeignet. Derartige Anstriche können sofort nach dem Trocknen befeuert werden. Die Anstrichsmasse wird beispielsweise verarbeitungsfertig vom Hersteller angeliefert und kann vor dem Auftragen mit Wasser, welches Trinkwasserqualität aufweisen sollte, verdünnt werden.Chemical-ceramic binding emulsions, for example, which solidify in air, are suitable as coating materials. Such coatings can be fired immediately after drying. The coating material is delivered ready for use by the manufacturer, for example, and can be diluted with water, which should be of drinking water quality, before application.
Durch solche Anstrichmassen, die auch als Coatings bezeichnet werden können, können die Oberflächen der als Auskleidung für Heizkessel und insbesondere Brennräume bzw. Brennkammern bestimmte Wärmedämmplatten verschlossen werden, so daß Schadstoffe nicht in die wärmedämmende Auskleidung eindringen können und eine Abrasion der Oberfläche derselben verhindert wird. Auch kann der Befall von Brenngut durch Faserteilchen verhindert werden.Such paints, which can also be referred to as coatings, can be used to seal the surfaces of thermal insulation panels intended as linings for boilers and in particular combustion chambers, so that harmful substances cannot penetrate the thermal insulation lining and abrasion of the surface is prevented. The contamination of fuel by fiber particles can also be prevented.
Die eingesetzten Coatings bilden eine harte, dünne Oberfläche, welche sich an die Oberfläche des Untergrundes anpaßt. In jedem Falle sind künstliche Fasern einschließlich künstliche keramische Fasern bzw. künstliche Mineral-Fasern für die Wärmedämmung bzw. den Schutz der Oberflächen der eingesetzten speziellen Wärmedämmplatten nicht erforderlich.The coatings used form a hard, thin surface that adapts to the surface of the substrate. In any case, artificial fibers, including artificial ceramic fibers or artificial mineral fibers, are not required for thermal insulation or to protect the surfaces of the special thermal insulation panels used.
Somit entspricht die erfindungsgemäße mikroporöse Wärmedämmplatte den neueren Anforderungen, daß zum Oberflächenschutz keine Gefahrenmaterialien wie beispielsweise künstliche Mineral-Fasern notwendig sind.Thus, the microporous thermal insulation board according to the invention meets the newer requirements that no hazardous materials such as artificial mineral fibers are necessary for surface protection.
Die Erfindung ist aber nicht auf mikroporöse Wärmedämmplatten zum Auskleiden der Brennräume von Heizkesseln beschränkt. Vielmehr schließt sie auch für andere Zwecke bestimmte Formteile aus mikroporösen Dämmstoffen ein, welche mit den beschriebenen Beschichtungen versehen sind.However, the invention is not limited to microporous thermal insulation panels for lining the combustion chambers of boilers. Rather, it also includes molded parts made of microporous insulation materials for other purposes, which are provided with the coatings described.
