Description

The The invention relates to a Abbrandkörper and a method for Production of such Abbrandkörpers.

At the Set fire of stoves or other fireplaces, firelighters with burned-on bodies are used which burn together with the fuel and this, which often heavy flammable is, kindle.

Known firelighters are from compact bodies built up where possible much fast burning material is contained in the bodies. By the compact, dense structure have the known primer the disadvantage that they gnaw at the beginning of the burn or by melting wax or other energy sources drip into the fireplace let, which allows evaporation of the energy source without inflammation. This is disadvantageous because these fuels are often dangerous to the environment and / or unhealthy when inhaled.

The CH 157 291 discloses a soaked wood wool support which is to be spun into a solid compact rope. Thereafter, the spun ropes are impregnated with an oil or wax. The disadvantage here are the expensive raw materials, since weave wood wool is needed. In addition, a compact dense rope is created which has an unfavorable burning behavior under soot.

The US 2,107,054 suggests a dense blending of sawdust and shredded material together with wax or prickly oil, which should thereafter cool compactly and be cut into plates or cylinders. Again, a compact dense body of a long, a briquette corresponding burn behavior is to have, which does not burn off quickly and large temperature and light.

Also the US 3,297,419 shows a synthetic log consisting of a compact mass of sawdust and wax absorbed therein in addition to high temperature binders.

The EP 0 791 646 A2 discloses a brick-shaped lighter made of wax and sawdust, which in turn is densely pressed and is characterized by appropriate external shapes to allow oxygen to reach the sealed outer surfaces for combustion. A clean, fast burning without soot is not possible.

The DE 102 07 949 A1 Finally, shows a firelighter made of wood wool, which is densely pressed or the wood wool body wrapped tightly compressive, with an ignition device is to be provided on the firelighter, which is to cooperate with a friction surface similar to a match.

all Previously known firelighters have in common that they are compact and / or densely pressed bodies, which do not allow a high burning temperature from the beginning of the burnup causing them to smoke and soot tend. In addition, the known firelighters are partly not Renewable raw materials or even when burning harmful Fabric releasing materials produced.

Of the Invention is therefore the object of an improved Abbrandkörper and to provide a method of making it, from the beginning of the burned out soot-free and Burns without release of harmful substances.

These Task is characterized by a Abbrandkörper with the characteristics of Claim 1, and a method for the method for producing a Abbrandkörpers solved according to the features of claim 6.

According to the invention is a Abbrandkörper proposed, which is formed from a mixture of wood chips, in particular Wood shavings, up to 20 mm in length with small proportions of less than 10% of wood flour, with the Mix loosely, forming interconnected cavities, under compressed low pressure, and the mixture is impregnated with wax and with a thin, wrapped in up to 0.2 mm thick wax layer, wherein the wax in Pressing the mixture is cold and thus forms the binder of Abbrandkörpers.

hereby is from the beginning through the thin, with energy carrier soaked and components surrounded by air sufficient combustion Ensures oxygen, whatever an optimal combustion allows.

Of the Abbrandkörper is preferably a firelighter or furnace lighter and especially approximate cubic or conical is designed.

Likewise, it can be provided according to an embodiment of the invention that the Abbrandkörper is irregularly granulated and isolated. This allows the Abbrandkörper dosed individually and in the Fire pit to be placed.

As well can be provided according to a further embodiment of the invention be that the burned body a garden torch is designed and in particular elongated rod-shaped is.

It may be provided to advantage, the mixture with a dye to soak or to apply such a dye to the mixture.

• – Pressen der Mischung in einer Form unter Abkühlung bis zum Erstarren des Wachses, wobei unter geringem Druck verpresst wird, sodass zwischen den Bestandteilen der Mischung miteinander verbundene Hohlräume gebildet werden.

According to the second aspect of the invention, a method for producing a burned-off body according to one of claims 1 to 5 is proposed, which is characterized by the method steps:

• - adding a mixture of wood shavings, in particular wood shavings, of up to 20 mm in length with small amounts of less than 10% of wood flour to a vessel containing heated liquid wax solid at room temperature,
• Introducing the wax into the mixture for 10 to 15 minutes while mixing the mixture in the vessel,
• - lifting out of the soaked mixture from the vessel,
• - Pressing the mixture in a mold with cooling until solidification of the wax, wherein it is pressed under low pressure, so that interconnected voids are formed between the components of the mixture.

A advantageous process step provides that the compression (Squeeze) in a rejuvenating Square or round tube takes shape.

One Another advantageous method step provides that the shape chilled becomes.

According to one Embodiment of the method, the pressed molding to a Isolated granules.

The burned body 1 is doing this by a mixture of wood chips 2 (Wood shavings) of up to 20 mm in length with an admixture of less than 10% of wood flour 3 formed as a carrier of a wax, which wax also a thin up to 0.2 mm thick wax layer 5 forms around the components of the mixture.

The mixture is loose, forming interconnected cavities 4 designed and pressed under low pressure.

In this case, the wax is cooled during the pressing, whereby this is a holding the Abbrandkörper in the form of binder Abbrandkörpers 1 forms.

An inventive Abbrandkörper is prepared by admixing a mixture of wood chips 2 with a length of up to 20 mm, wood shavings are particularly well-suited due to their rough surface finish and small proportions of less than 10% of wood flour 3 in a container with heated liquid, solid at room temperature wax.

The Mixture then becomes for Leave for 10 to 15 minutes with mixing of the mixture in the vessel, the wax being in the surfaces of the Ingredients of the mix feeds and these soaks. On the subsequent lifting the soaked Mixture from the vessel remains then on the surface still a thin one still soft to liquid Wax layer.

After that the mixture is pressed into a final shape by pressing in a mold of the burned-off body brought, with the wax solidifies under cooling. It will The mixture is held in the mold under low pressure and pressed so that formed between the components of the mixture interconnected voids become. The wax then forms the binder of Abbrandkörpers.

The Compression (compression) can be done in a tapered square or round tube be done as a mold, the mold can be cooled to increase productivity.
