Definitions

  • the present invention relates to a firing device which can be fired in particular with liquid fuel, for example with ethanol, according to the preamble of claim 1.
  • the present invention addresses the problem of providing a generic firing device, an improved or at least another embodiment, which is characterized on the one hand in particular by a visually appealing flame image during operation of the firing device and on the other hand by a secure operation.
  • the invention is based on the general idea to provide at least one air-conducting flow element which on the one hand generates an appealing, since unusual, flame image and on the other forms a boundary of a combustion chamber of the firing device, so that no direct and dangerous contact with the open flame is possible.
  • the firing device can be fired, for example, with ethanol, which burns soot and odorless and therefore an operation of the firing device according to the invention in closed rooms, that is, in particular without fireplace, allows.
  • the firing device now has at least one flow / delimiting element delimiting the combustion chamber of the firing device and having a tangential air inlet, for example radially overlapping in the circumferential direction, thereby producing a flame vortex during operation of the firing device.
  • a flow / delimiting element lies with its one end, seen in the circumferential direction, within the adjacent flow / delimiting element, while it, with its other end, viewed in the circumferential direction, lies outside the adjacent flow / delimiting element ,
  • an at least small radial gap is present in each case between them, through which an air flow can flow tangentially into the combustion chamber during operation of the firing device.
  • the arrangement in the case of a plurality of flow-limiting elements is comparable to a guide-blade arrangement in a turbine.
  • an unusual flame image can be generated, which produces a not to be underestimated optical stimulus for a viewer. Together with an appealing design of the remaining components of the firing device can thus be created a design element, which meets the highest requirements.
  • the at least one flow / restriction element effects a spatial delimitation of the combustion chamber of the firing device, so that immediate access into the combustion chamber, combined with an associated risk of injury, can be reliably ruled out.
  • the at least one arc-shaped flow / limiting element is also technically simple and therefore inexpensive to produce in many variants, so that additional design effects can be achieved by a different configuration or arrangement. In the following, there is often talk of several flow / restriction elements, it being understood that only a single flow / restriction element per firing device can be present.
  • At least one of the flow / restriction elements is at least partially transparent, in particular made of glass.
  • Such a transparent embodiment of at least one of the flow / limiting elements allows a direct view of the flame vortex arising in the firing device, wherein it is entirely conceivable that in the case of several flow / limiting elements, for example with a total of four flow / limiting elements, one number is transparent and the remainder is formed intransparent, which can also generate individual designerische effects cost.
  • the firing device may have a fan for regulating the flame pattern.
  • a blower can be provided, for example, in a bottom region of the firing device and act on the flame pattern formed in the combustion chamber via precisely defined nozzles with respect to their position. Depending on the power of the fan, this can be used, for example, to regulate the height of the resulting flames.
  • the flame picture can as well be changed by adjusting the flow / limiting elements (with two or more elements) via a suitable mechanism. By regulating the radial gap remaining between the flow / restriction elements with regard to its cross section, it is possible to influence the inflowing air quantity and thus the shape, velocity and velocity of the flame vortex.
  • the firing device expediently has a tube element arranged coaxially with the limiting elements and radially inside thereof so that the flame vortex (s) occur exclusively in an annular space between the outer limiting element (s) and the inner tube element.
  • the inner tube elements may be transparent or non-transparent and thereby achieve an additional design effect.
  • a plurality of, annularly arranged (flame) openings are preferably provided at the top of the reservoir for the liquid fuel, which connect an overlying combustion chamber with the fuel stored underneath in the reservoir.
  • capillary active and refractory materials such as metal foams and / or ceramic elements.
  • FIG. 1 has a firing device 1 according to the invention, a substantially cylindrical shape.
  • This cylindrical shape is in accordance with the FIG. 1 of a total of three, a combustion chamber 2 bounding, flow / limiting elements 3a, 3b and 3c formed.
  • a burner 4 is provided with a reservoir 5 for liquid fuel.
  • ethanol is considered as a liquid fuel since it does not produce soot or odor when burned.
  • the individual flow / delimiting elements 3a to 3c are formed in a circular arc and engage spirally with one another, that is, they lie with their one, circumferentially seen end within the adjacent flow / limiting element, while with its other, seen in the circumferential direction outside of the adjacent Flow / limiting element lie.
  • at least one small radial gap 6 is provided between two respective adjacent flow / limiting elements (for example, 3 a and 3 b), through which fresh air can flow tangentially into the combustion chamber 2 and thereby generates a helical air flow 9 in the combustion chamber 2.
  • the spiral engagement of the individual flow / restriction elements 3a to 3c is in particular from Fig. 3 clearly.
  • At least one of the illustrated flow / limiting elements 3a, 3b or 3c is at least partially transparent, in particular made of glass, and thereby allows a direct insight into the combustion chamber 2. It is of course conceivable that, for example, in a total of six flow / limiting elements 3 is a certain number transparent and the rest intransparent, for example, in change, is formed.
  • the drawn in the bottom region of the combustion chamber 2 burner 4 has at least one upward to the combustion chamber 2 directed towards opening 7, which may be formed, for example, point or line or in other shapes and thereby generates a respective individual flame image.
  • opening 7, as in the Fig. 1 shown, is arranged centrally to the storage container 5, so that during operation of the firing device 1, a central flame vortex 8 is formed or that several decentralized of the reservoir 5 and arranged to the combustion chamber 2 directed towards openings 7a to 7c (see. Fig. 3 ) are provided, so that during operation of the firing device 1 more, here three, flame vortex arise, which may in particular still intertwined.
  • openings 7a, 7b and 7c may of course also be formed either point-like, linear or in another shape. According to the Fig. 3 a flame vortex 8 is shown, as it usually arises in only one centrally disposed opening 7. The decentralized openings 7a, 7b and 7c are therefore drawn only with interrupted drawn line.
  • a blower not shown, can additionally be provided, which can preferably be adjusted steplessly.
  • the flame pattern can also be influenced by a change in the radial gap 6, for which purpose at least one flow / limiting element 3 with a suitable adjusting mechanism is adjustable.
  • the firing device 1 may have a coaxial with the flow / limiting element (s) 3a, 3b and 3c and radially inside thereof arranged tubular element, so that the flame vortex 8 exclusively in an annulus between the / the outer flow / restriction element (s) 3a, 3b and 3c and the inner tubular element occurs.
  • a plurality of openings 7a, 7b and 7c a plurality of intertwined flame vortices 8 are created which spiral upwards within the annular space formed by the pipe element and the flow / restriction elements 3a, 3b and 3c.
  • the inner tube element can be made transparent or non-transparent and thus also trigger special optical effects.
  • a plurality of burners 4 can be arranged on an ascending coil and thereby produce a special optical effect.
  • the firing device 1 has a plurality of axially aligned burner 4, which are arranged for example radially in the middle of the combustion chamber 2.
  • the individual flow / limiting elements can be used 3a, 3b and 3c may be stationary or variable with respect to their position. The latter variant, which should usually find application in higher-value design lines, allows by the position of the individual flow / limiting elements 3a to 3c and thus by an individual influencing the radial column 6 a direct influence on the flame pattern.
  • the desired flame vortex 8 can also be achieved with only a single flow / delimiting element 3, provided that this has overlapping regions in the circumferential direction, so that in turn a radial gap 6 can arise.
  • the firing device is according to the FIG. 5 formed, in which a continuous, that is closed in the circumferential direction, cylindrical flow / limiting element 3 is provided, which, however, in contrast to the previously shown and described flow / limiting elements 3 flow openings 10, with which the flame vortex generated within the combustion chamber 2 can be. Via guide elements 11, a direction of rotation of the flame vortex 8 can be specified. Also in the in the FIGS. 4 and 5 shown embodiments, a direct access from the outside into the combustion chamber 2 is not possible, whereby a risk of burns can be reduced.
  • an optically extremely appealing flame image namely at least one flame vortex 8
  • a visual stimulus not to be underestimated
  • a corresponding designerischen design of the other components of the firing device 1 thus can create a very high-quality furnishing, which triggers a feeling of well-being in the viewer, especially during operation of the firing device.
