Abstract
In order to create a safe and simply designed fire column, the flame of which is fed from a fuel tank, in particular for bioethanol, and is surrounded by an outer casing (4), wherein supply air flows in largely axially in the lower region of the outer casing via a plurality of guide elements (3) and is preferably set in helical rotation to form a swirling flame, according to the invention the outer casing (4) is placed over the guide elements (3). The outer casing (4) is preferably centered in an upright position by outer edges (3a) of the guide elements (3).
Claims19
Fire column, the flame of which is fed by a fuel container, the fire column includes a cylindrical base part, the cylindrical base part is surrounded by a cylindrical outer casing, the base part has a smaller diameter than the outer casing establishing an annular gap therebetween, wherein supply air flows through the annular gap in largely axially in the lower region of the outer casing via a plurality of guide elements disposed within the annular gap and is set in a helical rotation to form a vortex flame,
- wherein the outer casing is placed over the guide elements,
- and wherein the outer casing rests on a plurality of radially extending pins, the pins and the guide elements are attached directly to the base part.
A fire column assembly, the flame of which is fed by a supply of fuel from an integrated fuel container, said assembly comprising:
- a tubular outer casing, the outer casing having an open bottom and an open top, the bottom having an inside diameter, the outer casing adapted to ensconce a live flame while aspirating ambient air through the bottom and exhausting hot combustion gases through the top,
- a stand plate,
- a generally cylindrical fuel container extending upwardly from the stand plate, the fuel container having an upper end comprising a fuel outlet elevated above the stand plate, a portion of the fuel container extending through the bottom of the outer casing and generally centered therewith,
- at least one helical guide element directly attached to the fuel container, the guide element configured to induce a rotational vortex in the live flame, the guide element having a crest height measured radially from the fuel container such that a major diameter of the guide element is smaller than the inside diameter of the outer casing adjacent the bottom thereby enabling the guide element to fit inside the outer casing, the guide element having a start adjacent the stand plate and an end adjacent the upper end of the fuel container,
- a plurality of support extensions projecting from the cylindrical housing of the fuel container, each support extension having a radial projection greater than the crest height of the guide element, the plurality of support extensions being axially aligned with one another,
- and wherein the plurality of support extensions are spaced above the stand plate so that the bottom of the outer casing is stationed above the stand plate thereby creating an annular draft intake clearance between the fuel container and the bottom of the outer casing through which ambient air is aspirated directly into the outer casing.
A fire column assembly configured to produce a live flame set in rotational vortex, said assembly comprising:
- an elongated vertically-oriented tubular outer casing having a uniform wall thickness, the outer casing being a unitary member fabricated from an optically transparent material, the outer casing having an open bottom and an open top, the bottom having an inside diameter, the outer casing adapted to encase a live flame while aspirating ambient air through the bottom and exhausting hot combustion gases through the top,
- a stand plate,
- a generally cylindrical fuel container extending upwardly from the stand plate, the fuel container having an upper end comprising a fuel outlet elevated above the stand plate, a portion of the fuel container extending through the bottom of the outer casing and generally centered therewith,
- a plurality of helical guide elements directly attached to the fuel container, the plurality of guide elements having a common crest height measured radially from the fuel container such that a major diameter of the guide elements is smaller than the inside diameter of the outer casing adjacent the bottom, each guide element having a start adjacent the stand plate and an end adjacent the upper end of the fuel container,
- a plurality of support extensions projecting from the cylindrical housing of the fuel container, each support extension having a radial projection greater than the crest height of the guide elements, the plurality of support extensions being axially aligned with one another,
- and wherein the start of each guide element is located above the support extensions so that the outer casing entirely overlaps the start of each guide element.
