Abstract

The liquid hydrocarbon burner contains a catalytic element centrally disposed in the pot. Also claimed, is the treatment process for the preparation of the catalyst.

Description

La présente invention est relative à un brûleur à hydrocarbure liquide composé d'un pot à paroi simple.The present invention relates to a liquid hydrocarbon burner composed of a single-walled pot.

Dans un brûleur du type considéré il faut, pour brûler hygiéniquement un hydrocarbure liquide gazéifier celui-ci et le mélanger en quantités convenables avec un oxydant, en l'occurrence l'oxygène de l'air. L'hydrocarbure liquide s'évapore au contact de la tôle constituant le fond du pot du brûleur.In a burner of the type under consideration, in order to hygienically burn a liquid hydrocarbon, gasify it and mix it in suitable quantities with an oxidant, in this case oxygen from the air. The liquid hydrocarbon evaporates on contact with the sheet metal constituting the bottom of the burner pot.

Cette tôle doit être suffisamment chaude pour évaporer rapidement la fraction de l'hydrocarbure liquide qui distille à la plus haute température.This sheet must be hot enough to quickly evaporate the fraction of the liquid hydrocarbon which distills at the highest temperature.

Dans le cas du fioul commercial, cette température est de l'ordre de 370°C. Les "pétroles" distillent à plus basse température, les huiles, notamment les huiles agricoles combustibles distillent généralement à plus haute température.In the case of commercial fuel oil, this temperature is of the order of 370 ° C. "Oils" distill at lower temperatures, oils, especially combustible agricultural oils, generally distill at higher temperatures.

Si l'évaporation du composant combustible le plus réfractaire ne se fait pas, le pot dont le fond constitue la plaque évaporatrice s'engorge, et si cette évaporation se fait dans un laps de temps trop long, le combustible polymérise en un agglomérat noir compact.If the most refractory fuel component does not evaporate, the pot whose bottom constitutes the evaporator plate becomes clogged, and if this evaporation takes too long, the fuel polymerizes into a compact black agglomerate .

Si la température est trop élevée (de l'ordre de 550°C pour le fioul), il se produira une pyrolyse qui cassera les molécules d'hydrocarbure en un floconnage de crasse noire pulvérulente, c.à.d. de suie. Cette pyrolyse doit se faire dans le pot du brûleur en présence d'une turbulence de vitesse ascensionnelle moyenne suffisante pour empêcher les dépôts.If the temperature is too high (around 550 ° C for fuel oil), pyrolysis will occur which will break up the hydrocarbon molecules into a flaking of powdery black grime, i.e. of soot. This pyrolysis must be carried out in the burner pot in the presence of turbulence with an average rate of rise sufficient to prevent deposits.

L'invention a donc pour but de créer des conditions de combustion optimales, tant du point de vue rendement calorifique que du point de vue "hygiène".The object of the invention is therefore to create optimal combustion conditions, both from the point of view of heat efficiency and from the "hygiene" point of view.

Pour réaliser cet objectif conformément à l'invention le brûleur à hydrocarbure liquide selon l'invention est caractérisé par la présence d'un élément catalyseur disposé centralement dans le pot.To achieve this objective in accordance with the invention, the liquid hydrocarbon burner according to the invention is characterized by the presence of a catalyst element placed centrally in the pot.

Toujours selon l'invention l'élément catalyseur précité est constitué d'un acier inox sans nickel, appartenant aux aciers ferritiques au chrome réfractaires à coeur.Still according to the invention the aforementioned catalyst element consists of a nickel-free stainless steel, belonging to the ferritic chromium steels refractory to the core.

Dans sa forme de réalisation préférentielle l'élément catalyseur est constitué par un ensemble de lamelles disposées concentriquement autour d'un axe situé, en position d'utilisation, au centre du pot du brûleur et l'ensemble des lamelles précitées présente, selon une coupe menée par l'axe précité, la forme d'un champignon.In its preferred embodiment, the catalyst element consists of a set of blades arranged concentrically around an axis located, in the position of use, in the center of the burner pot and all of the aforementioned blades present, in a section led by the aforementioned axis, the shape of a mushroom.

Une caractéristique remarquable de l'invention réside dans le fait que chacune des lamelles précitées est constituée de telle sorte qu'en position d'utilisation la partie supérieure de l'élément catalyseur se trouve allégée tandis que la partie inférieure se trouve alourdie et que chacune des lamelles précités comporte, toujours en position d'utilisation, une partie supérieure arrondie approximativement en forme de quart de cercle et une partie inférieure à plus fortes pertes de charge s'étendant sensiblement vers le bas du pot de brûleur, les parties à plus fortes pertes de charge présentant des orifices pour le passage de l'air comburant.A remarkable characteristic of the invention resides in the fact that each of the aforementioned lamellae is constituted such that in the position of use the upper part of the catalyst element is lightened while the lower part is made heavier and that each of the aforementioned strips comprises, still in the position of use, a rounded upper part approximately in the shape of a quarter of a circle and a lower part with higher pressure losses extending substantially downwards from the burner pot, the parts with stronger pressure losses presenting holes for the passage of combustion air.

D'autres détails et avantages de l'invention ressortiront de la description qui sera donnée ci-après d'un brûleur à hydrocarbure liquide selon l'invention. Les notations de référence se rapportent aux figures ci-annexées.Other details and advantages of the invention will emerge from the description which will be given below of a liquid hydrocarbon burner according to the invention. The reference notations refer to the appended figures.

La figure 1 est une vue schématique et en élévation d'un brûleur à mazout à paroi unique équipé d'un élément catalyseur selon l'invention.Figure 1 is a schematic view in elevation of a single wall oil burner equipped with a catalyst element according to the invention.

La figure 2 est une vue en élévation d'un lamelle constitutive de l'élément catalyseur selon l'invention.Figure 2 is an elevational view of a constituent strip of the catalyst element according to the invention.

La figure 3 est, à une échelle différente, une vue partiellement en copie et partiellement en élévation d'une variante de l'élément catalytique selon l'invention.Figure 3 is, on a different scale, a view partially in copy and partially in elevation of a variant of the catalytic element according to the invention.

La figure 4 est une représentation schématique et en élévation de l'élément catalytique selon la figure 3.FIG. 4 is a schematic representation in elevation of the catalytic element according to FIG. 3.

L'élément catalytique 1, 1' représenté par ces figures est destiné à équiper le pot 2 d'un brûleur à mazout à paroi unique. Il est réalisé sous la forme d'un assemblage de lamelles 3, 4 disposées en étoile.The catalytic element 1, 1 ′ represented by these figures is intended to equip the pot 2 with a single wall oil burner. It is produced in the form of an assembly of strips 3, 4 arranged in a star.

Les lamelles 3, 4 sont produites, selon un premier mode de réalisation, à partir d'un acier inox sans nickel, appartenant aux aciers ferritiques au chrome réfractaires à coeur, grâce à une teneur en silicium supérieure à 0,40 à 0,50. Il est également possible de faire appel à un acier stabilisé au titane, chromisé dans une phase ultérieure.The lamellae 3, 4 are produced, according to a first embodiment, from a nickel-free stainless steel, belonging to ferritic chromium steels refractory to the core, thanks to a silicon content greater than 0.40 to 0.50 . It is also possible to use titanium stabilized steel, chromized in a later phase.

L'élément catalytique représenté aux diverses figures dans ses deux formes d'exécution est constitué d'un ensemble de lamelles 3, 4 présentant une partie supérieure arrondie 3', 4'. Le poids de la partie supérieure de l'ensemble des lamelles est inférieur au poids de la partie inférieure 3", 4" de ce même ensemble de lamelles.The catalytic element shown in the various figures in its two embodiments consists of a set of blades 3, 4 having a rounded upper part 3 ', 4'. The weight of the upper part of the set of slats is less than the weight of the lower part 3 ", 4" of this same set of slats.

Les lamelles 3 sont du type essentiellement représenté par la figure 1 tandis que les lamelles 4 appartiennent au type d'élément catalytique représenté par les figures 2 - 4. Dans les deux types de lamelles la partie supérieure 3', 4' de celles-ci est arrondie sous la forme d'un arc de cercle s'étendant sur environ 90° tandis que la partie inférieure 3", 4" s'étend, en position d'utilisation, verticalement ou sous un faible angle vers le bas.The lamellae 3 are of the type essentially represented by FIG. 1 while the lamellae 4 belong to the type of catalytic element represented by FIGS. 2 - 4. In the two types of lamellae the upper part 3 ′, 4 ′ thereof is rounded in the form of an arc of a circle extending over approximately 90 ° while the lower part 3 ", 4" extends, in the position of use, vertically or at a slight downward angle.

Dans les lamelles sont prévus des orifices ou des creux plus ou moins larges permettant le passage de l'air. Dans les lamelles représentées à la figure 1 ces orifices portent les références 5 et 6.In the slats are provided more or less wide orifices or hollows allowing the passage of air. In the strips shown in FIG. 1, these orifices bear the references 5 and 6.

Aux figures 2 et 3 ces orifices sont désignés par les références 5' et 6'. En se référant aux figures 2, 3 et 4 on remarquera que des lamelles composites constituées d'une lamelle courbe 4', de plus grand rayon, et une lamelle courbe 4"' se présentant sous la forme d'une ligne brisée sont obtenues en pliant la lamelle 4"' et sa partie inférieure 4" le long d'un axe Y-Y (figure 2). On obtient donc un ensemble de lamelles de deux types différents comme illustré schématiquement par la figure 4.In Figures 2 and 3 these holes are designated by the references 5 'and 6'. Referring to FIGS. 2, 3 and 4, it will be noted that composite lamellae constituted by a curved lamella 4 ', of larger radius, and a curved lamella 4 "' in the form of a broken line are obtained by folding the strip 4 "'and its lower part 4" along an axis YY (FIG. 2). This gives a set of strips of two different types as shown diagrammatically in FIG. 4.

Après avoir décrit en détail la structure de l'élément catalyseur selon l'invention on soulignera que la présence de cet élément dans le coeur réactionnel, c.à.d. le centre, du brûleur permet d'abaisser la température critique de démarrage de la combustion dans les conditions molaires particulières régnant à la surface de l'élément catalyseur.After having described in detail the structure of the catalyst element according to the invention, it will be emphasized that the presence of this element in the reaction core, i.e. the center of the burner makes it possible to lower the critical temperature for starting combustion under the particular molar conditions prevailing on the surface of the catalyst element.

Un élément catalyseur formé de lamelles d'acier au chrome à 16-17 % grâce à la présence de fer pentacarbonyle et de chrome carbonyle CR(CO)6 apparaissant après un certain temps de fonctionnement remplit ces conditions.A catalyst element formed from 16-17% chromium steel lamellae thanks to the presence of iron pentacarbonyl and chromium carbonyl CR (CO) 6 appearing after a certain operating time fulfills these conditions.

Dans certains cas cependant, des impuretés métallurgiques présentent dans l'acier inhibe partiellement la catalyse. Il est admis qu'il doit s'agir du silicium dont la présence réduit la vitesse d'oxydation de l'acier inoxydable (inox 430) à des températures supérieures à 400°C. Une concentration inférieure à 0,25 % de silicium provoquerait une destruction trop rapide de l'élément catalyseur, tandis qu'une concentration supérieure à 0,35 % de silicium empêche la formation de la couche d'oxyde où les catalyseurs fer pentacarbonyle et chrome carbonyle se fixent.In some cases, however, metallurgical impurities present in the steel partially inhibits catalysis. It is accepted that it must be silicon, the presence of which reduces the oxidation rate of stainless steel (430 stainless steel) at temperatures above 400 ° C. A concentration of less than 0.25% of silicon would cause the catalyst element to be destroyed too quickly, while a concentration of more than 0.35% of silicon prevents the formation of the oxide layer where the catalysts iron pentacarbonyl and chromium carbonyl attach.

L'invention vise donc également un procédé de traitement d'un feuillard en acier inox au chrome réfractaire à coeur selon lequel le feuillard est préalablement décapé à l'aide d'un acide, tel que l'acide chlorhydrique, sulfurique ou fluorhydrique. Le décapage est effectué jusqu'à ce que le feuillard en acier inoxydable ait atteint en surface les qualités catalytiques qui en sont attendues.The invention therefore also relates to a method for treating a strip of stainless steel with refractory chromium at the core, according to which the strip is previously pickled with an acid, such as hydrochloric, sulfuric or hydrofluoric acid. Pickling is carried out until the stainless steel strip has reached the expected catalytic qualities on the surface.

L'invention n'est pas limitée aux formes d'exécution décrites et des modifications pourraient y être apportées pour autant que celles-ci tombent dans le cadre des revendications ci-jointes.The invention is not limited to the embodiments described and modifications could be made thereto provided that they fall within the scope of the appended claims.
