Definitions

  • FIG. 8 clearly shows the inflow of air and the turbulent flame zone.
  • the glass cylinder is placed on the base (as with the U.S. 2014/0290643 A1 ) and can therefore e.g. B. easily knocked over by playing children. The risk of accidents and injuries is therefore considerable, especially since the outer shell, which begins here at the height of the brazier, can become relatively hot.
  • a second concentric glass cylinder was used for this purpose, which, however, significantly increased the construction effort.
  • the U.S. 2013/0011800 A1 discloses a pillar of fire composed of a multitude of parts. The construction cost is therefore relatively high.
  • the invention is therefore based on the object of improving such a fire column in terms of safety and construction costs. This object is achieved by a column of fire according to claim 1. Expedient refinements are the subject matter of the dependent claims.
  • the outer shell cools the outer shell (in particular the inner wall of the glass cylinder) through increased flow speed, so that the lower area of the glass cylinder (and possibly the middle area at the level of the flame exit above the fuel tank) remains relatively cool. This minimizes the risk of burns and the outer shell can be removed by grasping the lower, cool area without gloves to extinguish the flame.
  • the guide elements can be manufactured in a cost-saving manner together with the base part (incl. fuel receptacle) as a cast part, with the guide elements also being produced in one production step for the preferred formation of air vortices in oblique or helical form can become.
  • the outer shell preferably consists of refractory glass, in particular in the form of a cylinder with an open end.
  • Such tubes can be manufactured with high precision (to ensure the above-mentioned loose fit) and are relatively inexpensive due to the series production (e.g. for use in the chemical industry).
  • other shapes and materials are also possible, e.g. B. a metal tube with windows in the manner of a lamp or a metal grid or metal mesh.
  • the lower end of the outer shell preferably rests on a plurality of radially aligned pins which are fastened to a base part which surrounds the fuel container. This can also be designed for fuel paste or used to hold wood pellets or other fuels.
  • the base part is preferably made of metal in order to ensure the necessary stability together with a relatively heavy base plate, especially in the version as a so-called table fire.
  • the fire column can also be arranged higher, in order to increase the lighting effect, in particular with a holder in the form of a so-called patio heater for the terrace area or with a support, e.g. B. in the manner of a ground spike for the garden area.
  • the above pins can also be at the lower end of the z. B. three guide elements can be formed or attached, so that the number of components is further reduced.
  • the pins can be adjustable in height for adjusting the supply air cross-section, in particular they can be designed as eccentric pins, so that the flame pattern can be varied.
  • the outer shell can also have a wavy or stepped shape at the lower end in order to regulate the air gap by rotating it about the vertical axis.
  • Perforated discs in a horizontal orientation or perforated rings that can be rotated in opposite directions are also conceivable in order to regulate the supply air or to smother the fire in the fire column when the slots provided therein are closed.
  • the invention relates to a fire column according to a further aspect of the invention, the flame of which is fed by a fuel container, in particular for bio-ethanol, and is surrounded by an outer shell, with supply air flowing in largely axially in the lower area of the outer shell via a number of guide elements and is preferably set in a helical rotation to form a vortex flame, the outer shell being slipped over the guide elements.
  • the skin of outer edges of the vanes is preferably centered in the upright position.
  • the guide elements preferably surround the fuel tank.
  • the guide elements are attached in particular to this.
  • the lower end of the outer casing preferably rests on a plurality of pins, in particular radially aligned pins.
  • the pins are preferably attached to a base surrounding the fuel container.
  • the base part preferably has a base plate.
  • the base plate is preferably made of metal.
  • the base plate is esp. Detachably connected.
  • the base is preferably mounted on an elevated mount or support.
  • the pins are preferably formed or attached to the respective lower end of the guide elements.
  • the guide elements are preferably formed in one piece on the base part, in particular as a cast part with three guide elements offset by 120°.
  • a fuel container provided for the fire column may be provided to hold wood pellets or fuel.
  • the pins are preferably adjustable in their height and in particular designed as an eccentric.
  • the outer shell is preferably designed as a one-piece glass cylinder, in particular as a refractory tube, or made of metal with openings, in particular as a mesh.
  • the lower inner edge of the outer shell is preferably ground and/or melted conically.
  • a perforated plate is preferably used, under which air inlet openings are provided.
  • the fuel container provided for the fire column preferably has a partial cover (9) that is open in the center, which is in particular shaped like a roof or a truncated cone. Additional air inlet openings are preferably provided in the upper region of the fuel tank, with the fuel tank preferably being double-walled on its circumference.
  • a fire column 1 is shown with a base part 2, which has a fuel container 2a and a base plate 2b.
  • a plurality of guide elements 3 are arranged on the base part 2, which are designed here as helical metal sheets in order to generate an air turbulence in an outer shell 4 placed over it.
  • This is preferably designed as a transparent glass cylinder and thus allows a view of the base part 2 here.
  • the flame enclosed by the outer shell 4 on the periphery is fed with fuel (of any consistency possible), in particular bio-ethanol or fuel paste from the (recessed) fuel container 2a and receives the required amount of air via an air inlet opening 6 (in the form of an annular gap) in the lower Area of the fire column 1, more precisely at the lower end of the outer shell 4, which is open at the front.
  • fuel of any consistency possible
  • bio-ethanol or fuel paste from the (recessed) fuel container 2a and receives the required amount of air via an air inlet opening 6 (in the form of an annular gap) in the lower Area of the fire column 1, more precisely at the lower end of the outer shell 4, which is open at the front.
  • the inflowing air is deflected by the guide elements 3 into a vortex or flow with a twist.
  • the amount of air can be varied over the cross section of the air inlet opening 6, where z. B. pins 5 are adjusted in their altitude.
  • the cross section over the base plate 2b corresponds approximately to the passage volume between the base part 2 and the outer shell 4, with the guide elements 3, which are relatively thin here, hardly reducing the passage.
  • Those on pins 5 here three Piece with a pitch of 120 ° on the circumference of the base part
  • seated outer shell 4 is slipped with a tight fit or slight clearance over the guide elements 3 and touches them at least in some places.
  • the column of fire 1 is shown in an elevated version, namely in Fig. 2a with a frame-like support 2c to z. B. to be placed on a terrace.
  • the support 2c is designed in the manner of a rod or spear in order to be anchored in the garden soil with this holder in the manner of a ground spear.
  • In 3 is the Pillar of Fire according to 1 shown in perspective. From this, the helical course of the guide elements 3 is clearly visible, as is the upper opening in the base part 2, in order to form a fuel tank 2a there.
  • the flame fed from this indicated schematically, also rises rotating or at least flickers in the glass cylinder 4 due to the targeted air vortices.
  • the achievable height, e.g. B. up to 3 ⁇ 4 of the outer shell 4 can be adjusted in particular by the combustion behavior of the fuel (preferably ethanol) and by the air supply.
  • FIG. 4 two side views of the base part 2 are shown, each of which has four guide elements 3 here, ie with a 90° division.
  • the guide elements 3 are here largely aligned in the axial direction (to the vertical axis) and have a shape that widens upwards in order to form four nozzle channels on the circumference of the base part 2 and to accelerate the supply air from the opening 6 .
  • the outer shell 4 is slipped over the guide elements 3 with a tight fit, so that their outer edges 3a almost touch the inner wall of the outer shell.
  • the inner edge 4 ′ is preferably ground conically, so that the outer casing 4 can be placed in a self-centering manner in order to then be supported on the pins 5 .
  • the pins 5 are formed here on the lower end of the guide elements 3, in particular cast in one piece.
  • the guide elements 3 are inclined to the dash-dotted vertical axis and have thin extensions 3' in the form of so-called winglets. These can easily be glued or soldered onto the guide elements 3 in order to increase the turbulence.
  • the pins 5 are attached here separately from the guide elements 3 on the base part, preferably by means of eccentric bushings 5', in order to vary the height of the glass cylinder 4 and the supply air cross section in relation to the base plate 2b.
  • the fire column is designed for the combustion of wood pellets, whereby the principle of the wood gasifier is applied.
  • a perforated plate 7 is used in the lower area of the fuel tank 2a, under which several air inlet openings 8 (here in the form of perforations or slits) are provided.
  • air inlet openings 8 here in the form of perforations or slits
  • the air inlet openings 8 can also be placed in the bottom or standing plate 2b, so that the pellets in the fuel tank 2a flow evenly through and the desired wood gas is formed by carbonization or pyrolysis (sub-stoichiometric partial combustion). This is mixed at the upper end of the fuel tank 2a with the secondary air swirled over the guide elements 3 and then burns (depending on the air supply) with a lower or higher flame.
  • the air supply is controlled by (ring) slides (not shown) on the air inlet openings 8 (or also 6 and/or 8' in Figure 5b ) adjustable.
  • the fuel tank 2a has a hood or partial cover 9 which is open in the center and which is shaped in particular like a roof or a truncated cone.
