Abstract

igniter consisting of a mixture of a fuel and at least an additive which is a binder and / or an accelerator is characterized in that the fuel is a renewable organic raw material or residue, but no wood in any Form is, and this paraffin is added.

Description

The The present invention relates to a lighting aid for lighting solid fuels such as wood or charcoal, especially for solid fireplaces Fuels, consisting of renewable organic resources and at least one addition.

State of the art

As is known it difficult, if not almost impossible, common solid fuels like Wood in logs, coal, and the like only with the help of matches, So without any additional firelighters, to burn.

Therefore are used in chimneys, tiled stoves, charcoal grilling, etc. for a long time additional firelighters used, mostly in liquid or solid form. The liquid Form, for example, as methylated spirits, is more likely to charcoal grilling, So outdoors, used. Divide by fireplaces and tiled stoves this liquid firelighters because of the imminent danger of deflagration mostly.

In In this area come solid firelighters in different versions and material compositions.

From the DD 262 445 A5 For example, an igniter and a method for its production is known in which thin platelets of a combustible product, in particular about 2 to 8mm thick pieces of wood immersed in a paraffin melt bath and several of them are packed after draining and cooling in a combustible shell.

Currently available in the stores are mainly three forms of firelighters. The first version consists of natural wood, usually in the form of sawdust, sawdust or the like, which soaked with wax is. In the second version become the firelighters in the form of white, rather unpleasant smelling cubes based on kerosene, which is made with the help of a resin, Surfactants and a hardener is included.

A third version, from the DE 202 09 646 U1 is known, consists of a paraffin core, around which a paraffin impregnated wood wool rope section is wound.

alternative for the use of firelighters can Be used fuel that is already designed so that he burns well.

For example, is from the US 3,297,419 A a synthetic fuel log known, which consists of sawdust and at least one additive to improve the burning behavior. Here, wax is used as the first additive to more easily ignite the log at room temperatures, and optionally a second additive which improves the continuous burning of the billet at high temperatures. This billet is prepared in a process in which first the wax is heated and liquefied, then mixed with the sawdust and optionally further admixture, and then the mixture is cooled and formed into a billet in a pressing operation.

In The last few years are in the field of fuels, especially because of the rise in the price of fossil fuels oil and coal, strong progress in the development and use of renewable organic fuels he follows. From renewable raw materials and / or organic residual and Waste materials were different fuels, mostly in the form of Pellets, developed and put on the market.

From the DE 103 34 645 A1 For example, a fuel is known which is pressed and pelletized from a mixture of 20 to 80% wood in comminuted form and a proportion of organic constituents of renewable raw materials, without the addition of a binder.

From the DE 10 2004 042 659 A1 For example, a fuel body is known which receives an agricultural waste, a first additive for heating value increase, and a second additive for reducing slag formation. Here are as agricultural waste primarily waste from the grain harvest, as a first additive residual products of grain processing, and proposed as a second additive to reduce the formation of slag lime.

In the DE 103 57 282 A1 The enrichment of wood and straw fuels with iron and / or manganese is proposed to improve the burning behavior.

Finally, out of the DE 20 2006 014 651 U1 a fuel of compressed renewable organic raw materials known, which consists of 72 to 83% by weight of combustible organic raw materials and / or agricultural residues, 15 to 25% by weight of natural organic oils and / or fats to optimize the calorific value and slag formation from a mixture , and 2 to 3% by weight of sodium perborate as an oxygen source.

According to the state of the art, agricultural raw materials and residues, such as straw, are already used in fuels, usually in combination with various additives, but not with wax.

at firelighters is for agrarian raw materials and residuals so far only the use of wood in the form of sawdust or Wood wool known, but already in conjunction with wax.

task

The technical problem to be solved by the invention is to a kindling for common To produce solid fuels that mixes from agricultural raw materials and residues with paraffin, although not the meanwhile scarce and therefore expensive wood is used. This ignition aid is also easy and inexpensive to manufacture and to portion, as well the burning behavior is optimized.

These Task is solved by the igniter invention.

embodiment

The Ignition aid according to the invention consists of a mixture of miscanthus and paraffin, which also for the production of candles also as candle wax.

miscanthus is known by the biological name Miscanthus. There is of it different varieties such as Miscanthus Gigensis or Miscanthus sinesis

miscanthus is a plant easily cultivable in Central Europe, too the one on good soil permanently very good yields from up to about 20 tonnes of dry matter per hectare of acreage achieved. For the inventive ignition the entire stem and leaf mass is used.

These Mass becomes first by chopping up a size of 0 brought up to 10mm. Paraffin is heated to about 90 ° C. With constant stirring mean the hot Paraffin added the crushed miashmallow straw until a mixing ratio of about 55% by weight of miscanthus to 45% by weight of paraffin is.

at this mixing ratio can the Work very well and the best possible burning behavior is achieved.

The Mixture of miscanthus and paraffin is then allowed to cool to about 35 ° C. Subsequently, will the mixture is pressed by a piston press to a rod-shaped lighter. This lighter can have a round or rectangular cross-section, wherein the Dimensions for diameter or Width preferably in the range between 2 and 4 cm.

This lighter can be distributed in the form of rods with a length of about 20 to 30 cm. Here then the user simply breaks off pieces of the desired size. Alternatively, too ready to use pieces from about 1.5 to 2.5 cm in length to be in the trade.
