Definitions
- the present invention relates to chemical sweeping and / or catalytic of combustion devices and conduits smoke. It relates more particularly to a combustible agent solid chemical and / or catalytic destruction of the soot, its manufacturing process and its use.
- “soot” in the present description means the deposits of all kinds that form in the devices of heating and more particularly in the flues. These deposits can be of various nature, in particular particles carbonaceous matter, entrained ashes and above all tars. These are mainly deposited in the lower part of the flues. Training and filing of these materials are particularly emphasized in the case from burning solid fuels such as coal and wood, especially with closed hearths or "inserts".
- Chimney sweeping products are currently on the market called “chemical” or “catalytic”. Some of these products contain sulfur to decompose tar to facilitate their combustion with all the risks that this involves, in particular the risk of a chimney fire, because it is necessary heat the duct to the maximum to make the product effective, and the risk of deterioration of the conduits by caustic soda or its decomposition products.
- Document FR-A-2 554 458 describes a combustible agent solid acting preventively or curatively on deposits and soot in the calorie generators.
- This agent can understand, among others, a combustible cellulosic material particulate, an active preventive or curative agent for soot and tar deposits and optionally a binder.
- the agglomerates obtained, for example in the form of briquettes, sticks or granules are introduced into an active hearth, about one kilogram per tonne of fuel, the agglomerate containing a few grams or tens of grams of anti-soot agent per kilogram of agglomerate.
- paraffin wax as a binder for materials in the manufacture of fire starters and artificial logs is known from documents US-A-4 147 518 and US-A-3,297,419 respectively.
- This last document provides incorporate organometallic additives into artificial logs, in proportion less than 0.1% and whose effect is improve the terminal combustion of logs, or nitrates at a rate of 5% by weight to simulate the crunches produced by an actual wooden log. There is no suggestion an effect on chimney sweeping.
- the invention is based on the new concept of realizing a combustible solid mass incorporating a destructive agent soot and especially tar.
- the combustion of this mass allows the soot-destroying agent to volatilize as it burns and come to contact with soot and tar.
- the above components are found in substantially homogeneous mixture, although one can envisage, for example, the use of successive layers of elements (a) and (b) linked by element (c), or a surface coating final mixing by the only component (c) or (a) or the mixture (c + a), for example to accelerate inflammation.
- Particulate solid cellulosic combustible material preferably consists of wood particles, for example in the form of sawdust, flour, chips, fibers or the like.
- other combustible materials can be used cellulosic, for example grinding or chopping products cereal straw, crushed and dried residue from certain household waste (plant residues) or residues pulp mills.
- the particle size is advantageously between 0.1 and 10 mm for sawdust and wood flour.
- Other materials are longer (chips or fibers) but their thickness is then preferably understood between 0.1 and 2 mm.

Description
La présente invention concerne le ramonage chimique et/ou catalytique des appareils de combustion et des conduits de fumée. Elle concerne plus particulièrement un agent combustible solide de destruction chimique et/ou catalytique de la suie, son procédé de fabrication et son utilisation.The present invention relates to chemical sweeping and / or catalytic of combustion devices and conduits smoke. It relates more particularly to a combustible agent solid chemical and / or catalytic destruction of the soot, its manufacturing process and its use.
Par "suie", dans la présente description, on entend les dépôts de toute nature qui se forment dans les appareils de chauffage et plus particulièrement dans les conduits de fumée. Ces dépôts peuvent être de nature diverse, notamment des particules de matière carbonée, des cendres entraínées et surtout des goudrons. Ces derniers se déposent principalement dans la partie inférieure des conduits de fumée. La formation et le dépôt de ces matières sont particulièrement accentués dans le cas de la combustion de combustibles solides tels que le charbon et le bois, en particulier avec les foyers fermés ou "inserts".By "soot" in the present description means the deposits of all kinds that form in the devices of heating and more particularly in the flues. These deposits can be of various nature, in particular particles carbonaceous matter, entrained ashes and above all tars. These are mainly deposited in the lower part of the flues. Training and filing of these materials are particularly emphasized in the case from burning solid fuels such as coal and wood, especially with closed hearths or "inserts".
L'accumulation de ces matières et notamment des goudrons dans les cheminées est dangereuse car ces matières sont inflammables et sont à l'origine des feux de cheminée. Elles sont aussi à l'origine du mauvais tirage des cheminées et appareils de combustion car elles rétrécissent la section des conduits. Un ramonage traditionnel avec un hérisson ne peut venir à bout des goudrons qui forment une croûte dure, collée aux parois du conduit de sorte que, même après un ramonage mécanique traditionnel, le risque de feu de cheminée persiste. The accumulation of these materials and in particular tar in chimneys is dangerous because these materials are flammable and cause chimney fires. They are also at the origin of the bad draft of the chimneys and apparatuses because they narrow the section of ducts. A traditional sweeping with a hedgehog cannot overcoming the tars which form a hard, stuck crust to the walls of the duct so that even after mechanical sweeping traditional, the risk of chimney fire persists.
On trouve actuellement sur le marché des produits de ramonage dits "chimiques" ou "catalytiques". Certains de ces produits renferment du soufre destiné à décomposer les goudrons pour faciliter leur combustion avec tous les risques que cela comporte, notamment le risque d'un feu de cheminée, car il faut chauffer le conduit au maximum pour rendre le produit efficace, et le risque de détérioration des conduits par la soude caustique ou ses produits de décomposition.Chimney sweeping products are currently on the market called "chemical" or "catalytic". Some of these products contain sulfur to decompose tar to facilitate their combustion with all the risks that this involves, in particular the risk of a chimney fire, because it is necessary heat the duct to the maximum to make the product effective, and the risk of deterioration of the conduits by caustic soda or its decomposition products.
La littérature scientifique et les brevets énumèrent de nombreux autres agents chimiques ou catalytiques destinés à empêcher la formation de dépôts dans les fours et les cheminées ou même à détruire ces dépôts une fois qu'ils ont été formés, mais ces agents sont le plus souvent d'un emploi peu pratique, notamment lorsqu'ils sont présentés sous forme liquide ou sous forme de poudre. Les agents liquides nécessitent des buses d'injection et leur emploi ne peut donc être envisagé avec les appareils de chauffage domestiques ; quant aux agents en poudre, leur emploi est délicat car il faut ajouter une poudre en dosage plus ou moins précis sur un feu plus ou moins soutenu, très difficile à mesurer et à maítriser. En outre une grande partie de la poudre ou de ses produits de décomposition est entraínée dans l'atmosphère, ce qui représente une perte et des risques de pollution.Scientific literature and patents list many other chemical or catalytic agents intended for prevent deposits from forming in ovens and chimneys or even destroy these deposits once they have been formed, but these agents are most often of an impractical use, especially when presented in liquid form or in powder form. Liquid agents require nozzles injection and their use can therefore not be considered with domestic heaters; as for powdered agents, their use is delicate because it is necessary to add a powder in more or less precise dosage on a more or less sustained fire, very difficult to measure and control. Furthermore a large part of the powder or its decomposition products is entrained in the atmosphere, which represents a loss and pollution risks.
Le document FR-A-2 554 458 décrit un agent combustible solide agissant de façon préventive ou curative sur les dépôts et la suie dans les générateurs de calories. Cet agent peut comprendre, entre autres, une matière combustible cellulosique particulaire, un agent actif préventif ou curatif pour la suie et les dépôts goudronneux et facultativement un liant. Les agglomérés obtenus, par exemple sous forme de briquettes, de bûchettes ou de granulés sont introduits dans un foyer actif, à raison d'environ un kilogramme par tonne de combustible, l'aggloméré renfermant lui-même quelques grammes ou dizaines de grammes d'agent anti-suie par kilogramme d'aggloméré.Document FR-A-2 554 458 describes a combustible agent solid acting preventively or curatively on deposits and soot in the calorie generators. This agent can understand, among others, a combustible cellulosic material particulate, an active preventive or curative agent for soot and tar deposits and optionally a binder. The agglomerates obtained, for example in the form of briquettes, sticks or granules are introduced into an active hearth, about one kilogram per tonne of fuel, the agglomerate containing a few grams or tens of grams of anti-soot agent per kilogram of agglomerate.
L'emploi de cire de paraffine comme liant pour des matières cellulosiques dans la fabrication d'allume-feux et de bûches artificielles est connu des documents US-A-4 147 518 et US-A-3 297 419 respectivement. Ce dernier document prévoit d'incorporer aux bûches artificielles des additifs organométalliques, en proportion inférieure à 0,1 % et dont l'effet est d'améliorer la combustion terminale des bûches, ou des nitrates à raison de 5 % en poids pour simuler les craquements produits par une bûche en bois réelle. Il n'y a aucune suggestion d'un effet sur le ramonage des cheminées.The use of paraffin wax as a binder for materials in the manufacture of fire starters and artificial logs is known from documents US-A-4 147 518 and US-A-3,297,419 respectively. This last document provides incorporate organometallic additives into artificial logs, in proportion less than 0.1% and whose effect is improve the terminal combustion of logs, or nitrates at a rate of 5% by weight to simulate the crunches produced by an actual wooden log. There is no suggestion an effect on chimney sweeping.
Le document US-A-3 637 355 décrit aussi des bûches artificielles à base de sciure de bois et de cire de paraffine. Ces bûches renferment des colorants de flamme, y compris des sels de métaux en proportion minime, de l'ordre de 1 à 2 % dans l'exemple. Rien n'est indiqué concernant un possible effet de ramonage des cheminées.Document US-A-3,637,355 also describes logs artificial sawdust and paraffin wax. These logs contain flame dyes, including metal salts in minimal proportion, of the order of 1 to 2% in The example. Nothing is indicated regarding a possible chimney sweeping.
Les inconvénients précités des agents de ramonage connus sont réduits ou supprimés par l'emploi de l'agent solide de destruction des suies, ou agent de ramonage, de l'invention, et par le mode préféré de sa mise en oeuvre.The aforementioned drawbacks of chimney sweepers known are reduced or eliminated by the use of the solid agent soot destruction, or chimney sweeping agent, of the invention, and by the preferred mode of its implementation.
L'invention repose sur le concept nouveau de réaliser une masse solide combustible incorporant un agent de destruction de la suie et notamment des goudrons. La combustion de cette masse permet à l'agent de destruction de la suie de se volatiliser au fur et à mesure de la combustion et de venir au contact de la suie et des goudrons.The invention is based on the new concept of realizing a combustible solid mass incorporating a destructive agent soot and especially tar. The combustion of this mass allows the soot-destroying agent to volatilize as it burns and come to contact with soot and tar.
L'agent de ramonage de l'invention est donc constitué
d'un agrégat solide renfermant, comme constituants essentiels
:
De préférence les composants ci-dessus se trouvent en mélange sensiblement homogène, bien que l'on puisse envisager, par exemple, l'emploi de couches successives des éléments (a) et (b) liées par l'élément (c), ou encore un enrobage superficiel final du mélange par le seul composant (c) ou (a) ou le mélange (c + a), par exemple pour accélérer l'inflammation. On peut aussi mettre la totalité du composant (b) au centre ou dans l'axe central de la composition.Preferably the above components are found in substantially homogeneous mixture, although one can envisage, for example, the use of successive layers of elements (a) and (b) linked by element (c), or a surface coating final mixing by the only component (c) or (a) or the mixture (c + a), for example to accelerate inflammation. We can also put the entire component (b) in the center or in the central axis of the composition.
L'agent de ramonage de l'invention présente plusieurs avantages par rapport aux agents de ramonage de la technique antérieure, et notamment les suivants :
- il est "autonome", c'est-à-dire qu'il n'est plus besoin de faire un feu séparé et d'y ajouter une bûche artificielle ou une poudre en dosage mal réglé ; il est donc beaucoup plus facile à utiliser par n'importe quel utilisateur en toute sécurité et fiabilité, particulièrement dans les cheminées fortement encrassées,
- il est également plus performant en ce sens que le dégagement du produit actif va se poursuivre de manière régulière tout au long de la combustion ce qui donne à ce produit actif un temps suffisant pour traiter les goudrons, la combustion de l'agent de ramonage amenant les goudrons à une température permettant de les traiter de manière efficace. Le ramonage est donc obtenu plus rapidement que par emploi des techniques chimiques et/ou catalytiques connues.
- it is "autonomous", that is to say there is no longer any need to make a separate fire and to add an artificial log or a powder in the wrongly adjusted dosage; it is therefore much easier to use by any user in complete safety and reliability, particularly in heavily fouled chimneys,
- it is also more efficient in the sense that the release of the active product will continue regularly throughout the combustion, which gives this active product sufficient time to treat the tars, the combustion of the sweeping agent bringing tars at a temperature that allows them to be treated effectively. Chimney sweeping is therefore obtained more quickly than by using known chemical and / or catalytic techniques.
La matière combustible cellulosique solide particulaire est de préférence constituée de particules de bois, par exemple sous forme de sciure, de farine, de copeaux, de fibres ou analogues. On peut néanmoins utiliser d'autres matières combustibles cellulosiques, par exemple des produits de broyage ou hachage de paille de céréales, des résidus broyés et séchés de certaines ordures ménagères (résidus végétaux) ou des résidus d'usines de pâte à papier. La dimension des particules est avantageusement comprise entre 0,1 et 10 mm pour la sciure et la farine de bois. D'autres matières sont plus longues (copeaux ou fibres) mais leur épaisseur est alors de préférence comprise entre 0,1 et 2 mm.Particulate solid cellulosic combustible material preferably consists of wood particles, for example in the form of sawdust, flour, chips, fibers or the like. However, other combustible materials can be used cellulosic, for example grinding or chopping products cereal straw, crushed and dried residue from certain household waste (plant residues) or residues pulp mills. The particle size is advantageously between 0.1 and 10 mm for sawdust and wood flour. Other materials are longer (chips or fibers) but their thickness is then preferably understood between 0.1 and 2 mm.
L'agent chimique et/ou catalytique destructeur de suie et notamment de goudron peut être l'un quelconque des agents utilisables à cette fin et dont on peut trouver de nombreux exemples dans la littérature scientifique et les brevets. On mentionnera, sans que cette liste soit limitative, les sels d'ammonium tels que le chlorure, le nitrate, l'acétate ou le sulfate d'ammonium, les acétates et nitrates de potassium et/ou magnésium, les phosphates tels que les phosphates d'ammonium et les phosphates de métaux alcalins et alcalino-terreux, les carbonates, oxydes et hydroxydes de métaux alcalins et alcalino-terreux, par exemple ceux de sodium, potassium, calcium et ammonium. Les composés de métaux polyvalents tels que le cuivre, le manganèse, le fer et le cérium peuvent avoir un effet catalytique et sont donc utiles dans l'invention, par exemple à raison de 0,1 à 2 % en poids. Ces divers composés peuvent être utilisés seuls ou en mélanges. A titre d'exemples on peut citer :
- un mélange de nitrate de potassium et de sulfate d'ammonium (1 : 10 à 10 : 1 en poids),
- un mélange de sulfate d'ammonium et de chlorure de magnésium (2 : 10 à 10 : 2 en poids),
- un mélange de phosphate dicalcique, de chlorure d'ammonium, de sulfate de fer et de nitrate de calcium,
- un mélange de phosphate d'ammonium, de sulfate d'ammonium et de nitrate de cuivre,
- un mélange d'acétate de potassium et de nitrate de magnésium.
- a mixture of potassium nitrate and ammonium sulphate (1: 10 to 10: 1 by weight),
- a mixture of ammonium sulfate and magnesium chloride (2: 10 to 10: 2 by weight),
- a mixture of dicalcium phosphate, ammonium chloride, iron sulphate and calcium nitrate,
- a mixture of ammonium phosphate, ammonium sulfate and copper nitrate,
- a mixture of potassium acetate and magnesium nitrate.
Des résultats supérieurs ont été obtenus avec un mélange de P2O5 ou d'acide phosphorique et d'un sel d'ammonium, notamment un mélange de pentoxyde de phosphore et d'un sel d'ammonium à raison de 10-90 % en poids de l'un pour 90-10 % en poids de l'autre, par exemple un mélange de pentoxyde de phosphore et de sulfate d'ammonium (1 : 10 à 10 : 1 en poids) avec ou sans addition d'un composé de cuivre ou de manganèse.Superior results have been obtained with a mixture of P 2 O 5 or phosphoric acid and an ammonium salt, in particular a mixture of phosphorus pentoxide and an ammonium salt at a rate of 10-90% by weight of one for 90-10% by weight of the other, for example a mixture of phosphorus pentoxide and ammonium sulfate (1: 10 to 10: 1 by weight) with or without the addition of a composed of copper or manganese.
Le mécanisme d'action de l'agent destructeur de suie et de goudrons [élément (b) de l'invention] dépend dans une certaine mesure de l'agent choisi, mais, quel que soit cet agent, son mécanisme d'action est encore mal connu. Ce qui est constaté c'est que ces agents facilitent la conversion des dépôts goudronneux en cendres pulvérulentes et peu adhérentes qui se détachent plus facilement. Les sels d'ammonium se vaporisent facilement et servent d'entraíneurs pour les autres composés minéraux présents. Ils ont toutefois aussi une action propre de désagrégation des dépôts.The mechanism of action of the soot-destroying agent and of tars [element (b) of the invention] depends to some extent measure of the agent chosen, but, regardless of this agent, its mechanism of action is still poorly understood. What is found is that these agents facilitate the conversion of tar deposits in powdery and poorly adherent ash which detach more easily. Ammonium salts vaporize easily and serve as coaches for other compounds minerals present. However, they also have their own action disaggregation of deposits.
On pense donc que le mécanisme est principalement chimique mais que les métaux ou composés de métaux éventuellement présents, tels que ceux du fer, du cuivre ou du manganèse, peuvent avoir une action catalytique.We therefore think that the mechanism is mainly chemical but that metals or metal compounds possibly present, such as those of iron, copper or manganese, can have a catalytic action.
Les explications précitées ne doivent pas être considérées comme limitant l'invention de quelque manière que ce soit.The above explanations should not be considered as limiting the invention in any way is.
Le liant est une matière quelconque capable de maintenir la cohésion du mélange des éléments (a) et (b). La préférence est donnée à une cire de paraffine solide à la température ordinaire. En effet la paraffine est une matière combustible par effet de mèche et qui, à l'état fondu, peut imprégner les éléments (a) et (b) et, après refroidissement, maintient une bonne cohésion entre ces éléments dans le solide obtenu. On préfère une paraffine qui fond au-delà de 40°C. On peut toutefois également utiliser une colle naturelle, artificielle ou synthétique, et par exemple une colle vinylique, une résine thermoplastique, une matière amylacée, de l'acide stéarique.The binder is any material capable of maintaining the cohesion of the mixture of elements (a) and (b). The preference is given to a solid paraffin wax at room temperature. Indeed paraffin is a combustible material by wicking and which, in the molten state, can permeate the elements (a) and (b) and, after cooling, maintains good cohesion between these elements in the solid obtained. We prefer a paraffin which melts above 40 ° C. However, we can also use a natural, artificial or synthetic glue, and for example a vinyl adhesive, a thermoplastic resin, a starchy material, stearic acid.
Les proportions relatives des éléments (a, b et c) peuvent varier largement en fonction notamment de la nature propre de chacun des éléments de la composition, de leur porosité, de leur combustibilité et, pour l'agent de destruction de la suie, de son efficacité.The relative proportions of the elements (a, b and c) can vary widely depending in particular on the nature of each of the elements of the composition, their porosity, their combustibility and, for the soot-destroying agent, of its effectiveness.
Dans la plupart des cas, les proportions pondérales relatives seront de 20 à 80 % de (a), 10 à 40 % de (b) et 10 à 70 % de (c) pour 100 parties du mélange (a + b + c). Des matières additionnelles peuvent toutefois être présentes, soit comme diluants, par exemple de la silice et des silicates, soit comme additifs de combustion, soit comme agents modifiant l'esthétique, par exemple un colorant ou un pigment, soit à toute autre fin. Leur proportion pondérale ne dépassera pas la moitié de la proportion de (a + b + c) et restera de préférence inférieure à 10 % et, mieux, inférieure à 5 % de cette proportion.In most cases, the relative weight proportions will be 20 to 80% of (a), 10 to 40% of (b) and 10 to 70% of (c) per 100 parts of the mixture (a + b + c). Subjects additional may be present, either as thinners, for example silica and silicates, either as combustion additives, either as aesthetic modifiers, for example a dye or a pigment, or to any other end. Their weight proportion will not exceed half of the proportion of (a + b + c) and will preferably remain less than 10% and, better, less than 5% of this proportion.
On préfère toutefois les proportions suivantes :
L'agent combustible de destruction de la suie selon l'invention peut se présenter sous toute forme désirée soit régulière, par exemple cubes, cylindres, polygones quelconques, sphères, soit sous forme aléatoire. Dans le cas de foyers utilisant normalement le bois, on préfère une forme en bûche ou bûchette à la fois plus esthétique et plus pratique. Les dimensions de la bûche ou bûchette pourront être quelconques et seront de préférence approximativement celles des bûches de bois habituellement utilisées dans le foyer, correspondant le plus souvent à une longueur de 10 à 40 cm.The combustible agent for destroying soot according to the invention can be presented in any desired form, either regular, for example cubes, cylinders, any polygons, spheres, either in random form. In the case of homes normally using wood, we prefer a log form or log both more aesthetic and more practical. The dimensions of the log or log may be any and preferably will be approximately those of the logs of wood usually used in the hearth, corresponding to the more often at a length of 10 to 40 cm.
Le procédé de fabrication des agrégats de l'invention peut être du même type que celui utilisé classiquement dans la fabrication d'une bûche en sciure de bois et paraffine ou dans la fabrication d'une bûche simplement compressée, à la différence près que la matière combustible (a) est additionnée d'agent anti-suie (b) avant encollage ou enrobage par l'agent (c) ou au cours de celui-ci. Le mélange obtenu (a + b + c) peut être moulé à la presse ou extrudé, ou encore coulé dans des moules. Si le liant est utilisé sous forme de solution ou dispersion dans un solvant, on élimine celui-ci par évaporation ou séchage. On préfère que les éléments de l'agrégat soient répartis de manière sensiblement homogène, bien que l'on puisse aussi disposer l'agent (b) au centre ou par couches successives.The method of manufacturing the aggregates of the invention may be of the same type as that conventionally used in the manufacture of a log in sawdust and paraffin or in making a simply compressed log, unlike close that the combustible material (a) is added anti-soot agent (b) before sizing or coating with the agent (c) or during it. The mixture obtained (a + b + c) can be press molded or extruded, or cast in mussels. If the binder is used as a solution or dispersion in a solvent, this is removed by evaporation or drying. We prefer that the elements of the aggregate are distributed substantially homogeneously, although we can also arrange the agent (b) in the center or in successive layers.
L'agrégat, par exemple la bûche, obtenu peut ensuite, si désiré, être emballé dans une enveloppe en matière de préférence combustible qui facilitera l'inflammation, par exemple du papier, du carton ou du papier ou carton paraffiné ou traité pour faciliter son ignition.The aggregate, for example the log, obtained can then, if desired, be wrapped in an envelope preferably fuel that will facilitate inflammation, for example paper, cardboard or waxed or treated paper or cardboard to facilitate its ignition.
On mélange à la température de 80°C 400 parties en poids de sciure de bois sèche de granulométrie moyenne de 1 mm avec 200 parties en poids d'un mélange en parties égales en poids de sulfate d'ammonium et de pentoxyde de phosphore et 600 parties en poids de paraffine fondue. Après refroidissement partiel pour solidifier au moins en partie la paraffine, on extrude le mélange et on découpe des morceaux d'extrudés d'une longueur d'environ 30 cm, le diamètre moyen étant d'environ 12 à 15 cm. Ces morceaux ont l'apparence de bûches. On emballe ces bûches dans des sacs en papier, ce qui n'est toutefois pas indispensable.400 parts by weight are mixed at the temperature of 80 ° C. dry sawdust with an average particle size of 1 mm with 200 parts by weight of a mixture in equal parts by weight of ammonium sulfate and phosphorus pentoxide and 600 parts by weight of molten paraffin. After partial cooling to at least partially solidify the paraffin, the mixing and cutting pieces of extrudates of a length about 30 cm, the average diameter being about 12 to 15 cm. These pieces have the appearance of logs. We pack these logs in paper bags, which is however not essential.
On place une bûche de ce type dans un foyer à bois, préalablement éteint et dont la cheminée nécessite un ramonage et on enflamme cette bûche. La bûche brûle avec flamme pendant environ 30 minutes à 2 heures selon sa taille, et dégage de la chaleur qui échauffe la cheminée et ramollit les dépôts, tandis que le produit actif commence à traiter la cheminée. Ensuite la bûche continue de se consumer doucement tout en dégageant une fumée lente qui peut durer, par exemple, de 2 à 6 heures. L'action du produit actif se poursuit et l'on peut constater ensuite que les dépôts dans la cheminée ont été fortement réduits, sinon supprimés, ou encore ont été rendus friables ce qui permet leur détachement aisé. Dans le cas de cheminées très sales, le traitement peut être renouvelé.We place a log of this type in a wood fireplace, previously extinguished and whose chimney requires sweeping and we ignite this log. The log burns with flame for about 30 minutes to 2 hours depending on its size, and gives off heat which heats the chimney and softens the deposits, while the active product begins to treat the chimney. Then the log continues to burn slowly while giving off a slow smoke which can last, for example, from 2 to 6 hours. The action of the active product continues and we can then see that the deposits in the chimney have been greatly reduced, otherwise removed, or have been made crumbly which allows them easy detachment. In the case of very dirty chimneys, the treatment can be renewed.
Ainsi en quelques heures on obtient un résultat égal ou supérieur à celui obtenu en 8 à 10 jours de traitement avec les poudres du commerce.So in a few hours you get an equal result or higher than that obtained in 8 to 10 days of treatment with commercial powders.
Il convient de noter qu'il n'est pas nécessaire de mettre la bûche dans un foyer déjà allumé et entretenu. Tout au contraire les meilleurs résultats sont obtenus en l'absence de tout autre combustible.It should be noted that there is no need to put the log in an already lit and maintained fireplace. Everything at otherwise the best results are obtained in the absence of any other fuel.
De bons résultats ont également été obtenus avec un mélange de sulfate d'ammonium et de chlorure de potassium (40/60 en poids) ainsi qu'avec un mélange d'acétate de potassium et de sulfate d'ammonium (30/70 en poids) avec ou sans addition de nitrate de cuivre.Good results have also been obtained with a mixture of ammonium sulfate and potassium chloride (40/60 by weight) as well as with a mixture of potassium acetate and ammonium sulphate (30/70 by weight) with or without addition of copper nitrate.
