  • Prepared fire starters can be classified into three categories according to whether they are in solid form, liquid form or gelled form.
  • Solid fire starters are themselves separable into two classes according to whether they contain or do not contain liquid fuel. When solid fire starters contain liquid fuels, these are absorbed on a porous substrate itself combustible, or even included in a matrix of combustible polymeric substance.
  • the porous substrates are most often cellulose, or wood agglomerates, the polymer matrices of urea-formaldehyde or phenol-formaldehyde resins.
  • Liquid fuels are generally hydrocarbons, low molecular weight alcohols and their mixtures. When solid fire starters do not contain liquid fuels, they simply consist of one or more solid fuels at room temperature. This is the case of metaformaldehyde cubes or even wax or paraffin bars.
  • Liquid fire starters are most often formed by one or more hydrocarbons, by one or more alcohols or by mixtures of alcohols or hydrocarbons.
  • Gelled fire starters are basically made up of one or more compounds with one or more alcohol functions, such as ethyl alcohol or butyl glycol, one or more hydrocarbons, or mixtures of these two classes of associated products. optionally with a solvent of very polar nature such as water. Gelation is obtained generally thanks to the addition of long-chain organometallic salts, silica with high absorption power or organic polymers effective in very polar environments.
  • Liquid fire starters are most often made up of a single component. This component is either an hydrocarbon, or a low molecular weight alcohol. However, mixtures of liquid fuels or solutions of a solid fuel such as wax or paraffin are often used in a fuel acting as a solvent.
  • Liquid fire starters do not have the same technical drawbacks as solid fire starters because they can easily be distributed over a large area of solid fuel which is to be ignited. However, they still have major drawbacks. First of all, they are dangerous for the user due to the often very low flash points, further subjecting the marketing of these products to special labeling which is an important obstacle to their marketing.

This is particularly the case for combustion catalysts based on heavy metals and peroxides mainly when they are in the form of mineral salts.
  • Firelighters in gelled form are usually packaged in sachets or bottles so as to be poured onto the solid fuel to be ignited.
  • sachets In the form of dose sachets, they have the same technical drawbacks as solids since they only allow one-time ignition of the fuel, while not presenting the same dangers during storage, their packaging being generally sealed.

Description

Depuis que la pratique de l'allumage des combustibles solides â l'aide de papier journal et de brindilles de bois a été pratiquement abandonnée, le marché des allume-feux préparés a pris une large extension. On peut classer les allume-feux préparés en trois catégories selon qu'ils se présentent sous forme solide, sous forme liquide ou sous forme gélifiée.Since the practice of igniting solid fuels using newsprint and wood twigs has been largely abandoned, the market for prepared fire starters has expanded considerably. Prepared fire starters can be classified into three categories according to whether they are in solid form, liquid form or gelled form.

Les allume-feux solides sont eux-mêmes séparables en deux classes selon qu'ils contiennent ou ne contiennent pas de combustible liquide. Lorsque les allume-feux solides contiennent des combustibles liquides, ces derniers sont absorbés sur un substrat poreux lui-même combustible, ou encore inclus dans une matrice de substance polymère combustible. Les substrats poreux sont le plus souvent de la cellulose, ou des agglomérats de bois, les matrices polymères des résines urée-formol ou phénol-formol. Les combustibles liquides sont généralement des hydrocarbures, des alcools de bas poids moléculaire et leurs mélanges. Lorsque les allume-feux solides ne contiennent pas de combustibles liquides, ils sont simplement constitués par un ou plusieurs combustibles solides à température ambiante. C'est le cas des cubes de métaformaldéhyde ou encore des pains de cire ou de paraffine.Solid fire starters are themselves separable into two classes according to whether they contain or do not contain liquid fuel. When solid fire starters contain liquid fuels, these are absorbed on a porous substrate itself combustible, or even included in a matrix of combustible polymeric substance. The porous substrates are most often cellulose, or wood agglomerates, the polymer matrices of urea-formaldehyde or phenol-formaldehyde resins. Liquid fuels are generally hydrocarbons, low molecular weight alcohols and their mixtures. When solid fire starters do not contain liquid fuels, they simply consist of one or more solid fuels at room temperature. This is the case of metaformaldehyde cubes or even wax or paraffin bars.

Les allume-feux liquides sont le plus souvent constitués par un ou plusieurs hydrocarbures, par un ou plusieurs alcools ou encore par des mélanges d'alcools ou d'hydrocarbures.Liquid fire starters are most often formed by one or more hydrocarbons, by one or more alcohols or by mixtures of alcohols or hydrocarbons.

Les allume-feux gélifiés sont à la base constitués généralement par un ou plusieurs composés présentant une ou plusieurs fonctions alcools comme par exemple l'alcool éthylique ou le butylglycol, par un ou plusieurs hydrocarbures ou encore par des mélanges de ces deux classes de produits associés éventuellement à un solvant de nature très polaire tel que l'eau. La gélification est obtenue généralement grâce à l'addition de sels organo-métalliques à longue chaîne, de silice à haut pouvoir d'absorption ou de polymères organiques efficaces en milieux très polaires.Gelled fire starters are basically made up of one or more compounds with one or more alcohol functions, such as ethyl alcohol or butyl glycol, one or more hydrocarbons, or mixtures of these two classes of associated products. optionally with a solvent of very polar nature such as water. Gelation is obtained generally thanks to the addition of long-chain organometallic salts, silica with high absorption power or organic polymers effective in very polar environments.

Qu'ils soient utilisés pour l'allumage de poêles ou de cuisinières à combustible solide, de feux de cheminée, ou encore de barbecue, les allume-feux solides existants présentent de nombreux inconvénients. Ces inconvénients sont liés au fait que la surface de contact flamme issue de la combustion de l'allume-feu et combustible dont on veut réaliser l'ignition est très faible et qu'il est donc souvent nécessaire de répartir dans la masse du combustible solide une grande quantité d'allume-feu pour réaliser un allumage rapide du combustible. C'est le cas notamment lorsqu'il s'agit d'allumer des combustibles tels que anthracite, coke, agglomérés, ou encore de l'allumage d'un feu de cheminée.Whether used for lighting stoves or solid fuel stoves, chimney fires, or even barbecue, existing solid fire starters have many drawbacks. These drawbacks are linked to the fact that the flame contact surface resulting from the combustion of the fire starter and fuel which it is desired to ignite is very small and that it is therefore often necessary to distribute solid fuel in the mass. a large quantity of fire starters to achieve rapid ignition of the fuel. This is particularly the case when it comes to lighting fuels such as anthracite, coke, agglomerates, or even the lighting of a chimney fire.

De plus, lorsque les allume-feux solides contiennent des combustibles liquides, ils doivent être conditionnés sous films assurant une barrière efficace contre l'évaporation. Cette barrière n'étant jamais parfaite, le stockage de ces types d'allume-feux n'est pas sans danger, en particulier en périodes chaudes de l'année.In addition, when solid fire starters contain liquid fuels, they must be wrapped in films ensuring an effective barrier against evaporation. This barrier is never perfect, the storage of these types of fire starters is not without danger, especially in hot periods of the year.

On a essayé d'améliorer l'efficacité des allume-feux solides par l'incorporation d'additifs. Parmi les additifs proposés, on peut citer :

  • - les métaux sous forme de leurs sels minéraux ou sous forme de leurs composés organo-métalliques (savons, naphténates, chélates, etc...) ; _
  • - les peroxydes minéraux ou organiques.
Attempts have been made to improve the efficiency of solid fire starters by incorporating additives. Among the additives offered, there may be mentioned:
  • - metals in the form of their mineral salts or in the form of their organometallic compounds (soaps, naphthenates, chelates, etc.); _
  • - mineral or organic peroxides.

Toutefois, les gains de performance réalisés grâce à ces additifs sont minimes. Ceci est dû au fait que les additifs même présents en quantité suffisante ne sont pas en contact direct avec le combustible à allumer ; leur action sur la rapidité d'ignition du combustible n'est donc que très modérée.However, the performance gains achieved with these additives are minimal. This is due to the fact that the additives even present in sufficient quantity are not in direct contact with the fuel to be ignited; their action on the speed of ignition of the fuel is therefore only very moderate.

Les allume-feux liquides sont le plus souvent constitués par un seul composant. Ce composant est soit un aydrocarbure, soie un alcool de bas poids moléculaire. Toutefois, on fait souvent appel à des mélanges de combustibles liquides ou encore à des solutions d'un combustible solide tel que cire ou paraffine dans un combustible jouant le rôle de solvant.Liquid fire starters are most often made up of a single component. This component is either an hydrocarbon, or a low molecular weight alcohol. However, mixtures of liquid fuels or solutions of a solid fuel such as wax or paraffin are often used in a fuel acting as a solvent.

Les allume-feux liquides ne présentent pas les mêmes inconvénients techniques que les allume-feux solides car on peut facilement les répartir sur une grande surface du combustible solide dont on veut réaliser l'ignition. Ils présentent néanmoins encore des inconvénients majeurs. Tout d'abord, ils sont dangereux pour l'utilisateur en raison de points éclair souvent très bas, soumettant de plus la mise sur le marché de ces produits à un étiquetage spécial qui est un frein important à leur commercialisation.Liquid fire starters do not have the same technical drawbacks as solid fire starters because they can easily be distributed over a large area of solid fuel which is to be ignited. However, they still have major drawbacks. First of all, they are dangerous for the user due to the often very low flash points, further subjecting the marketing of these products to special labeling which is an important obstacle to their marketing.

Ensuite, l'incorporation d'additifs d'amélioration de la combustion pourtant particulièrement efficace et donc souhaitable dans le cas d'un allume-feu liquide est rendue difficile en raison de l'insolubilité ou de la très faible solubilité des additifs les plus efficaces dans les compositions liquides généralement utilisées. C'est le cas notamment des catalyseurs de combustion à base de métaux lourds et des peroxydes principalement lorsqu'ils se présentent sous la forme de sels minéraux.Then, the incorporation of combustion improvement additives, which is nevertheless particularly effective and therefore desirable in the case of a liquid fire starter, is made difficult because of the insolubility or very low solubility of the most effective additives. in the liquid compositions generally used. This is particularly the case for combustion catalysts based on heavy metals and peroxides mainly when they are in the form of mineral salts.

Les allume-feux sous forme gélifiée sont habituellement conditionnés en sachets-doses ou en flacons de manière à être versés sur le combustible solide à allumer. Sous forme de sachets-doses, ils présentent les mêmes inconvénients techniques que les solides puisqu'ils ne permettent de réaliser qu'un allumage-ponctuel du combustible, tout en ne présentant pas les mêmes dangers au stockage, leurs emballages étant généralement étanches.Firelighters in gelled form are usually packaged in sachets or bottles so as to be poured onto the solid fuel to be ignited. In the form of dose sachets, they have the same technical drawbacks as solids since they only allow one-time ignition of the fuel, while not presenting the same dangers during storage, their packaging being generally sealed.

Présentés en flacons, ils peuvent être répartis sur le combustible solide de la même manière que les liquides mais présentent alors l'inconvénient de rester à la surface du combustible sans le pénétrer, ne permettant d'obtenir ainsi qu'une faible efficacité.Presented in bottles, they can be distributed on solid fuel in the same way as liquids but then have the disadvantage of remaining on the surface of the fuel without penetrating it, thus making it possible to obtain a low efficiency.

On a maintenant trouvé que l'on pouvait d'une façon simple et efficace résoudre à la fois le problème de la sécurité des allume-feux liquides et celui de l'efficacité de la combustion grâce à l'allume-feu liquide perfectionné objet de la présente invention.It has now been found that the problem of the safety of liquid fire starters and that of combustion efficiency can be solved in a simple and effective manner by means of the improved liquid fire starter object of the present invention.

Mesure de degré de sécurité :Security measure:

La sécurité lors de l'utilisation d'un- allume-feu sera simplement appréciée par la mesure de son point éclair. En effet, plus le point éclair sera élevé et plus l'allume-feu sera considéré comme sûr. Un allume-feu pouvant être utilisé dans des conditions normales d'allumage à une température supérieure à son point éclair doit être considéré comme dangereux.Safety when using a fire starter will simply be appreciated by measuring its flash point. The higher the flash point, the safer the fire starter will be. A fire starter which can be used under normal conditions of ignition at a temperature above its flash point must be considered dangerous.

Mesure de l'efficacité d'allumaqe:Measurement of ignition efficiency:

Un boulet de charbon de bois aggloméré de forme régulière d'un poids de 39 1 1 g a été choisi comme combustible. Il est pesé avant et après immersion de 5 minutes. dans une solution d'allume-feu. On note la quantité d'allume-feu absorbée. Le boulet ainsi imprégné est alors enflammé et sa perte de poids est suivie pendant 30 minutes à compter du moment où la quantité d'allume-feu absorbée a théoriquement brûlé.A regular agglomerated charcoal ball weighing 39 1 1 g was chosen as fuel. It is weighed before and after 5 minutes immersion. in a fire starter solution. Note the amount of fire starter absorbed. The ball thus impregnated is then ignited and its weight loss is followed for 30 minutes from the time when the quantity of absorbed fire starter has theoretically burned.

La comparaison des pertes de poids des boulets au cours de la combustion permet de comparer directement l'efficacité des allume-feux.The comparison of the weight losses of the balls during combustion makes it possible to directly compare the efficiency of the fire starters.
