Definitions

• the invention relates to a burner having a container defining a fuel chamber for receiving a fuel, wherein the container has a container opening, which opens an access to the fuel chamber and limits a fuel surface, wherein the fuel is liquid, wherein in the fuel chamber, a liquid-absorbing and refractory material is arranged, which at least partially fills the fuel chamber, and wherein the liquid-absorbing material is covered with respect to the container opening with a cover made of a liquid-permeable, refractory material.
• Burners of the type mentioned above are e.g. From EP 1 026 444 B1, it is advantageous with such a burner that the fuel can not escape from the container opening even when the burner container tips over.
• the flame of such a burner tends to be extinguished, especially when used outdoors in strong winds.
• the flame height is quite low, so that such a burner is not particularly suitable for decorative purposes (e.g., lantern / torch / log fire, etc.).
• the object of the invention to provide a burner of the type mentioned, in which the flame generated is windproof. At the same time the burner should produce a higher flame, which is particularly suitable for decorative purposes.
• CONFIRMATION COPY The object is achieved by the container opening is partially covered with a cap consisting of a substantially flat portion and a subsequent, substantially frusto-conical portion which reduces the cross-section of the container opening, wherein on the surface of the substantially frusto-conical portion Plurality of openings is arranged.
• a further embodiment of the invention provides that a wick (for example made of metal) is arranged between the cover and the attachment. This produces an even higher flame so that the burner is particularly suitable for decorative purposes, e.g. as a garden torch, good.
• a wick for example made of metal
• a preferred embodiment of the invention provides that the liquid-absorbing and refractory material, which is arranged in the fuel chamber, is a ceramic fleece.
• a ceramic nonwoven not only has excellent refractory properties for such an application, but also has a very good liquid absorption, which allows to absorb more fuel than conventional burners, whereby a longer operating time is achieved.
• the cover of the burner according to the invention consists in a preferred embodiment of a ceramic or metal grid.
• a flat combustion surface is formed, which favors the combustion.
• it prevents the fluid-absorbing material from shifting or fraying.
• the burner according to the invention is preferably operated with a liquid fuel which consists of a combustible first liquid and a non-combustible second liquid.
• a liquid fuel which consists of a combustible first liquid and a non-combustible second liquid.
• the fuel advantageously consists of ethanol and water, wherein even more preferably the proportion of water between 5 vol .-% and 15 vol .-% of the fuel makes up.
• the flame produced with it burns with a bright, yellow-bright color, which is very well suited for decorative purposes.
• FIG. 1 shows a perspective view of a preferred embodiment of the burner according to the invention.
• FIG. 1 shows a preferred embodiment of a burner 1 according to the invention which comprises a container 2 which delimits a fuel chamber.
• the container 2 contains a liquid-absorbent and refractory ceramic fleece, which serves to receive a liquid fuel and which partially fills the fuel chamber defined by the container 2.
• the liquid-absorbent and refractory ceramic non-woven is covered in the upper region, which faces the opening of the container 2, with a cover only partially visible in the form of a ceramic grid 3.
• a top 4 Arranged on the container opening is a top 4 which comprises a substantially flat section 5 and a substantially frusto-conical section 6 adjoining the flat section 5.
• the attachment 4 reduces the cross section of the container opening, whereby a chimney effect is generated during combustion.
• a supply of oxygen to the flame serve the openings 7, of which only one is provided with a reference numeral, which are arranged on the substantially frusto-conical portion 6 of the attachment 3.
• the burner 1 further comprises a metal wick 8, which is formed in this case as a metal tab and partially protrudes from the plane defined by the substantially flat portion 5 of the attachment 4 level.
• a mechanism in the form of a slide may be provided, which is also particularly suitable for the control of the combustion and consequently the flame height.
• An alternative and inexpensive to produce variant provides a simple lid, which is arranged on the top 4. Particularly advantageously, the lid is screwed onto the container 2, so that evaporation of the fuel and penetration of moisture and foreign bodies into the container 2 is counteracted.
• the burner 1 may further be provided with means for securing it to objects such as e.g. a wall, be provided.
• a particular embodiment of the burner 1 provides that an elongate element not shown in FIG. 1 is connected to the container 2 and serves as a holder for the burner 1.
• the elongate element is preferably used as a stem of a torch, for example, to to insert the burner 1 into the ground or to attach it to a holder provided for this purpose on a wall.
