Abstract

1. Method of use of a firelighting fluid consisting of alcohol and a thickening agent for igniting coal and wood, the fluid being characterized by a content of 10 to 20% by volume water, 0,3 to 6% by weight of the thickening agent and rest alcohol.

Description

Die Erfindung betrifft eine Brennflüssigkeit zum Entzünden von Kohle und Holz.The invention relates to a fuel liquid for igniting coal and wood.

Kohle-und Holzanzünder für einen Grill oder Kamin gibt es in verschiedenen Ausführungsformen, beispielsweise als Brennpasten aus Brennspiritus und kolloidaler Kieselsäure, als mit Wachs getränkten Faserplatten als Brennöl auf Erdölbasis oder auch in Form von Brennspiritus. Alle diese Stoffe weisen aber Nachteile auf. So sind Brennpasten und in Stücken vorliegende getränkte Faserplatten aufgrund ihrer Konsistenz auf bestimmte Stellen lokalisiert, wodurch nur die angrenzenden Kohle-und Holzteilchen entzündet werden. Ausserdem verbrennen diese mehr oder - weniger festen Anzünder niemals rückstandsfrei und es können unerwünschte Crackstoffe entstehen. Dasselbe gilt auch für die Brennöle. Brennspiritus als Anzünder benetzt zwar die Kohle-und Holzstücke, aber er verdampft und verbrennt zu - schnell, um eine ausreichende Zündwirkung zu entfalten und ausserdem besteht die Gefahr des Verpuffens und "Spritens".Coal and wood lighters for a grill or fireplace are available in various embodiments, for example as fuel pastes made from methylated spirit and colloidal silica, as fiber plates impregnated with wax as petroleum-based fuel oil or in the form of methylated spirit. However, all of these substances have disadvantages. Because of their consistency, fuel pastes and impregnated fiberboard in pieces are localized at certain points, which only ignites the adjacent coal and wood particles. In addition, these more or - less solid lighters never burn residue-free and undesirable cracking substances can occur. The same applies to the fuel oils. Methylated spirits as igniters wet the coal and wood pieces, but they evaporate and burn too quickly - to develop a sufficient ignition effect and there is also the risk of deflagration and "fueling".

Aufgabe der Erfindung ist es, einen flüssigen Kohle-und Holz-anzünder zu schaffen, der eine gute flächige und andauernde Benetzung und durch ausreichend langsames Abbrennen ein sicheres Entzünden der Kohle-und Holzstücke gewährleistet.The object of the invention is to provide a liquid coal and wood lighter which ensures good widespread and continuous wetting and, by sufficiently slow burning, reliable ignition of the coal and wood pieces.

Diese Aufgabe wird durch eine Brennflüssigkeit zum Entzünden von Kohle und Holz gelöst, die aus einem durch Wasserzusatz und mindestens einem alkohollöslichen Verdickungsmittel phlegmatisierten Alkohol besteht.This object is achieved by a burning liquid for igniting coal and wood, which consists of an alcohol desensitized by the addition of water and at least one alcohol-soluble thickener.

Zweckmässige Zubereitungen der Brennflüssigkeit sind in den Unteransprüchen gekennzeichnet.Appropriate preparations of the fuel are marked in the subclaims.

Eine so phlegmatisierte Brennflüssigkeit bietet gegenüber herkömmlichen Anzündem wesentliche Vorteile. Durch den Wasserzusatz wird eine gewisse Phlegmatisierung erreicht und das Verbrennen des Alkohls verlangsamt. Durch Zusatz eines Verdickungsmittels wird die Brennflüssigkeit verdickt, wodurch das "Spriten" -also das schnelle Auseinanderlaufen -auf den zu entzündenden Kohle-und Holzstücken sowie auf deren Unterlage und das beim reinen Alkohol auftretende spontane Verdampfen und Abbrennen vermieden wird. Auch dieser Zusatz wirkt somit phlegmatisierend und ausserdem brennflüssigkeitssparend. Mit 40 bis 50 ml der phlegmatisierten Brennflüssigkeit kann praktisch jede Grillkohlenmenge verlässlich angezündet und zum Glähen gebracht werden. Zweckmässig wird die Brennflüssigkeit aus als hochrein au bezeichnenden Stoffen hergestellt, so dass davon ausgegangen werden kann. dass beim Verbrennen keine physiologisch schädlichen Crackstoffe entstehen, die geruchlich, geschmacklich und/oder gesundheitlich nachteilig sind. Das Ausschalten solcher Nebenerscheinungen ist insbesondere bei Verwendung als Grillanzünder wesentlich. Die erfindungsgemäss phlegmatisierte Brennflüssigkeit verbrennt praktisch rückstandsfrei. Durch das Verdickungsmittel kann die Viskosität der Brennflüssigkeit nach Bedarf eingestellt werden. Sie soll in jedem Fall noch ausreichend flüssig sein, um auf den anzuzündenden Kohle-und Holzstückenauseinander zu fliessen und diese im wesentlichen gleichmässig zu benetzen. Auf diese Weise ist sichergestellt, dass die Brennflüssigkeit zwischen den Kohle-und Holzteilchen verhältnismässig langsam abbrennt und diese entzündet werden. Durch das beim Abbrennen verdampfende Wasser wird eine ständige Kühlung der brennenden Masse bewirkt, die dadurch langsamer verdampft und demzufolge langsamer verbrennt. Es wurde beobachtet, dass die phlegmatisierte Brennflüssigkeit mit kleineren Flammen brennt als reiner Alkohol. Die Viskosität bevorzugter Zubereitungen wird so gewählt, dass diese durch Ausgabeöffnungen von mit Spezialverschlüssen, beispielsweise Sicherheitsverschlüssen versehenen Flaschen mit flexiblen, komprimierbaren Wandungen ausgegeben werden können. Auf diese Weise lässt sich die Ausgabemenge vom Verbraucher leicht dosieren.Such a stabilized fuel liquid offers significant advantages over conventional igniters. A certain phlegmatization is achieved through the addition of water and the burning of the alcohol is slowed down. By adding a thickening agent, the fuel liquid is thickened, so that the "spriting" - that is, the rapid divergence - on the pieces of coal and wood to be ignited and on their base and the spontaneous evaporation and burning that occurs with pure alcohol is avoided. This addition also has a desensitizing effect and also saves fuel. With 40 to 50 ml of the desensitized fuel liquid, practically any quantity of charcoal can be lit reliably and made to glow. The fuel liquid is expediently produced from substances which are referred to as highly pure, so that it can be assumed. that no physiologically harmful cracking substances are produced during burning that are disadvantageous in terms of smell, taste and / or health. Switching off such side effects is particularly important when used as a grill lighter. The desensitized fuel liquid according to the invention burns practically without residue. The viscosity of the fuel can be adjusted as required by the thickener. In any case, it should still be sufficiently liquid to flow apart on the pieces of coal and wood to be ignited and to wet them essentially uniformly. In this way it is ensured that the fuel liquid between the coal and wood particles burns up relatively slowly and these are ignited. Due to the water evaporating during the burning process, the burning mass is constantly cooled, which evaporates more slowly and consequently burns more slowly. It has been observed that the desensitized liquid burns with smaller flames than pure alcohol. The viscosity of preferred preparations is chosen so that they can be dispensed through dispensing openings of bottles with special closures, for example safety closures, with flexible, compressible walls. In this way, the amount dispensed can be easily metered by the consumer.

Es wurde gefunden, dass sich Isopropanol ganz besonders gut als phlegmatisierter Brennstoff eignet. Sein Brennwert bei einem Zusatz von 15 Vol.-% Wasser entspricht demjenigen von handelsüblichem Brennspiritus. Als Verdickungsmittel mit den gewünschten Eigenschaften, nämlich weitgehend oder vollständig rückstandsfreies Abbrennen und Vermeiden unerwünschter nachteiliger Crackstoffe bieten sich Hydroxypropylcellulose und Polyethylenoxid an.It has been found that isopropanol is particularly suitable as a desensitized fuel. Its calorific value with the addition of 15 vol.% Water corresponds to that of commercially available methylated spirit. Hydroxypropyl cellulose and polyethylene oxide are suitable as thickeners with the desired properties, namely largely or completely residue-free burning and avoidance of undesirable disadvantageous cracking substances.

Folgende Versuche veranschaulichen die vorteilhaften Ergebnisse, die mit phlegmatisiertem Alkohol, insbesondere Isopropanol, erzielt werden.The following experiments illustrate the advantageous results that can be achieved with phlegmatized alcohol, in particular isopropanol.

Die Versuche zeigen, dass auch phlegmatisierter Brennspiritus weitaus weniger verläuft und mehr als doppelt so lange brennt als reiner Brennspiritus.The experiments show that even phlegmatized methylated alcohol runs far less and burns more than twice as long as pure methylated spirit.

Ausgezeichnete Ergebnisse werden mit Isopro- . pandl erzielt, wobei optimale Ergebnisse mit einem Wasserzusatz von 10 bis 15 % Wasser und 0,40 bis 0,50 % Hydroxypropylcellulose zu beobachten sind. Auch ein Gemisch aus Hydroxypropylcellulose und Polyethylenoxid ergibt sehr gute Werte.Excellent results are obtained with Isopro. pandl achieved, whereby optimal results can be observed with a water addition of 10 to 15% water and 0.40 to 0.50% hydroxypropyl cellulose. A mixture of hydroxypropyl cellulose and polyethylene oxide also gives very good values.
