Abstract

1. Catalytic combustion device comprising a flask (1) containing a combustible liquid (2) a wick (4) plunging into the liquid and a burner (3) made from a porous material impregnated with a catalyst and to which the wick (4) is fixed, characterized in that the burner (3) comprises, at its lower part, an axial cavity (7) in which the wick (4) is engaged and, at its upper part, an annular cavity (6) whose outwardly turned wall (3a) has received the catalyst.

Description

On connaît des brûleurs à combustion catalytique qui sont montés sur une mèche destinée à être plongée dans de l'alcool ou autre liquide combustible. Par ca­pillarité, le liquide monte dans la mèche et parvient au brûleur qui, lorsqu'il a été préchauffé, assure sa combustion catalytique.Catalytic combustion burners are known which are mounted on a wick intended to be immersed in alcohol or other combustible liquid. By capillary action, the liquid rises in the wick and reaches the burner which, when it has been preheated, ensures its catalytic combustion.

Dans les brûleurs à combustion catalytique jusqu'a pré­sent réalisés, il arrive souvent que la mèche carbonise et s'encrasse.In catalytic combustion burners hitherto produced, it often happens that the wick chars and clogs.

La présente invention a pour objet un brûleur à combus­tion catalytique qui est perfectionné de manière à éviter ces inconvénients et offre en outre l'avantage de combiner la combustion catalytique du produit à diffuser avec une évaporation de ce même produit, les proportions de liquide brûlé par catalyse et diffusé par évaporation étant déterminées par construction.The present invention relates to a catalytic combustion burner which is improved so as to avoid these drawbacks and also offers the advantage of combining the catalytic combustion of the product to be diffused with an evaporation of this same product, the proportions of liquid burnt catalysis and diffused by evaporation being determined by construction.

Le brûleur selon l'invention est en matière poreuse et est caractérisé en ce qu'il comporte, à sa partie in­férieure, une cavité axiale dans laquelle peut être en­gagée la mèche destinée à amener le combustible au brû­leur et, à sa partie supérieure, une cavité annulaire dont la paroi tournée vers l'extérieur a reçu un cataly­seur.The burner according to the invention is made of porous material and is characterized in that it comprises, at its lower part, an axial cavity in which can be engaged the wick intended to bring the fuel to the burner and, at its upper part, an annular cavity whose wall faces outwards received a catalyst.

Dans ces conditions, la combustion catalytique se produit à une certaine distance de l'extrémité de la mèche; cel­le-ci ne risque donc pas de carboniser.Under these conditions, catalytic combustion occurs at a certain distance from the end of the wick; there is therefore no risk of it charring.

On a décrit ci-après, à titre d'exemple non limitatif, un appareil de combustion catalytique avec référence au dessin annexé dans lequel :

  • La Figure 1 est une vue en coupe verticale de l'appareil;
  • La Figure 2 est une vue en coupe verticale de son brûleur, à plus grande échelle.
A catalytic combustion device has been described below, by way of nonlimiting example, with reference to the appended drawing in which:
  • Figure 1 is a vertical sectional view of the apparatus;
  • Figure 2 is a vertical sectional view of its burner, on a larger scale.

A la Figure 1, on voit un flacon 1 contenant un liquide combustible 2. Dans le goulot tronconique 1a du flacon 1 est engagé un brûleur 3, auquel est fixée une mèche 4 plongeant dans le liquide 2, le goulot du flacon et le brûleur peuvent être recouverts par un capot 5. La mè­che 4 est en une matière textile très souple, ce qui lui permet de s'adapter à la profondeur du flacon 1.In Figure 1, we see a bottle 1 containing a combustible liquid 2. In the frustoconical neck 1 a of the bottle 1 is engaged a burner 3, to which is fixed a wick 4 immersed in the liquid 2, the neck of the bottle and the burner can be covered by a cover 5. The wick 4 is made of a very flexible textile material, which allows it to adapt to the depth of the bottle 1.

Comme on peut le voir à la Figure 2, le brûleur 3, qui est réalisé en une matière poreuse comporte à sa par­tie supérieure une cavité annulaire 6 débouchant à l'ex­térieur et, a sa partie inférieure, une cavité axiale 7 dans laquelle sera engagée l'extrémité supérieure de la mèche 4. Le brûleur 3 comporte extérieurement une por­tée tronconique 8 destinée à reposer sur le goulot tron­conique 1a du flacon 1.As can be seen in Figure 2, the burner 3, which is made of a porous material has at its upper part an annular cavity 6 opening to the outside and, at its lower part, an axial cavity 7 in which will be engaged the upper end of the wick 4. The burner 3 externally has a frustoconical surface 8 intended to rest on the frustoconical neck 1 a of the bottle 1.

La paroi de la cavité 6 tournée vers l'extérieur a reçu, par imprégnation, dans la zone périphérique 3a, un cata­lyseur qui permettra la combustion catalytique du produit combustible 2 contenu dans le flacon 1 et amené au brû­leur par la mèche 4.The wall of the cavity 6 facing outwards has received, by impregnation, in the peripheral zone 3 a , a catalyst which will allow the catalytic combustion of the combustible product 2 contained in the bottle 1 and brought to the burner by the wick 4.

Après préchauffage (environ une minute de combustion libre) le corps du brûleur ayant atteint une température suffisante, la combustion catalytique s'établira d'elle-­même.After preheating (approximately one minute of free combustion), the burner body having reached a sufficient temperature, the catalytic combustion will establish itself.

Il se produira par ailleurs une évaporation du liquide (sans combustion) à partir de la zone centrale 3b qui n'a pas reçu de catalyseur et se trouvera chauffée par conduction. Il se produira également une évaporation du liquide dans la zone 3c qui se trouve en dessous de la zone 3a, mais au-dessus de la portée tronconique 8.There will also occur an evaporation of the liquid (without combustion) from the central zone 3b which has not received a catalyst and will be heated by conduction. There will also be an evaporation of the liquid in zone 3 c which is below zone 3 a , but above the frusto-conical surface 8.

Il est clair qu'en faisant varier, par construction, l'importance relative des zones de catalyse 3a et d'éva­poration 3b et 3c on obtiendra, selon les résultats re­cherchés proportion également variable de produit catalysé et évaporé. L'extrémité de la mèche 4 se trouve au contact de la zone 3b qui n'est chauffée que par conduction et se trouve par suite à une température rela­tivement peu élevée; cette extrémité ne peut donc car­boniser.It is clear that by varying, by construction, the relative importance of the zones of catalysis 3 a and of evaporation 3 b and 3 c , according to the results sought, a variable proportion of catalyzed and evaporated product will also be obtained. The end of the wick 4 is in contact with the zone 3 b which is only heated by conduction and is therefore at a relatively low temperature; this end cannot therefore char.
