Abstract

A vegetation and charcoal burner, which is moveable, comprises a combustion vessel (11) for receiving matter to be burned, the combustion vessel being mounted upon a frame; wherein that the frame includes a handle (13) and an axle (15) carrying a wheel (14) and in that the combustion vessel is perforated with a plurality of holes (22). The combustion vessel may be shaped like a wheelbarrow or a wok. The burner may be fitted with a grid to separate the burning material from the bottom of the combustion vessel (11). The burner may be used as a barbecue, with charcoal placed below the grid.

Description

VEGETATION AND CHARCOAL BURNER The present invention relates to a vegetation and charcoal burner, in particular to a moveable burner.

Numerous designs of vegetation burners have been proposed and some are very popular. However, none have been found to be entirely successful at burning all types of garden waste, particularly fresh or wet cuttings. It is with this problem in mind that the present invention has been devised.

In its broadest sense, the present invention provides a burner for vegetation, charcoal or other essentially combustible material, the burner comprising a combustion vessel for receiving the matter to be burned, the combustion vessel being mounted upon a frame, characterised in that the frame includes an axle carrying a wheel and in that the combustion vessel is perforated with a plurality of holes, preferably around substantially the entire combustion vessel.

The combustion vessel may be of any overall shape, but having the same general form as a conventional wheelbarrow has proved to produce excellent results.

Alternatively, the vessel may be generally hemispherical, having the overall appearance of a wok, or an inverted cone or pyramid shape.

Preferably, the burner further comprises a generally horizontal, in use, grid within the combustion vessel to raise the material to be burned off the base of the burner.

Typically, the vessel and frame are made from galvanised steel. Typically, the wheel has a conventional pneumatic tyre, or sold material or metal rigid, construction.

The present invention enables a variable site appliance for bonfire purposes. As regards garden bonfires it takes up very little room and can be stored elsewhere to avoid unsightly areas in view of the garden.

Bonfires tend to burn on the windward side and this effect often limits the efficient burning of waste. The present invention allows for the burner to be presented to the wind at any angle, variable also throughout the burning cycle. Fresh and wet cuttings can in fact be burned immediately provided that there is sufficient heat generated to combust the material. Conventional bonfire characteristics do not allow for sufficient flow of air to generate this requirement of heat as the material to be burned often collapses over itself. When cool, the burner/appliance can be wheeled to garden beds where ashes are required and emptied.

The burner/appliance can then be stored away leaving gardens free of unsightly waste.

The above and other aspects of the present invention will now be described in further detail, by way of example only, with reference to the accompanying figures, in which: Figure 1 is a perspective view of a first embodiment of a burner in accordance with the present invention; Figure 2 is a perspective view of a second embodiment of a burner in accordance with the present invention; Figure 3 is a perspective view of the embodiment of Figure 1 including a grid; Figure 4 is schematic side view of the combustion vessel of the embodiment of Figure 3; Figure 5 is a schematic side view of the combustion vessel of the embodiment of Figure 2 including a grid; and Figure 6 is a perspective view of a third embodiment of a burner combustion vessel in accordance with the present invention.

Referring to Figure 1, a first embodiment of the burner of the present invention is shown generally at 10 and includes a combustion vessel 11 mounted upon a frame 12 including handles 13 and supporting an axel 15 carrying a wheel 14 to enable movement of the burner. Overall, this embodiment of the burner can be considered to have the appearance of a conventional wheelbarrow. The combustion vessel is generally rectangular in plan view with side walls 20 extending upwardly and slightly outwardly from a base 21. A plurality of perforations 22 are made in the side walls 20 and base 21. As shown, preferably substantially the whole surface of the base 21 and wall 20 is perforated to allow maximum air flow through the perforations into the combustion vessel 11.

Tests have shown that the embodiment of Figure 1 is excellent at burning all sorts of garden waste and is as equally effective burning damp materials. The material to be burned is simply loaded into the combustion vessel and ignited in a conventional way, using combustion aids such as firelighters as necessary.

Figure 2 shows an alternative embodiment 30 wherein the combustion vessel 31 is generally hemispherical, having the appearance of a wok. Woks are, of course, well known in many forms of ethnic cooking, notably Chinese cookery, for the high temperatures that can be generated and this advantage can be applied readily to the present invention.

The burner of the present invention offers several advantages including the ability to be able to turn the burner, in use, as necessary to allow for changes in wind direction or wheeled to another location. With a burner of similar dimensions to a conventional wheelbarrow it has been found to be possible to move the burner even with the combustion vessel full of burning material. The ability to move the burning material into the wind enables more complete combustion than has hitherto been possible with conventional burners, except in the stillest of wind conditions. Of course, when burning has been completed, it is possible to use the burner as a conventional barrow. This is particularly advantageous as, after burning, the ashes can be readily transported for disposal or distribution around the rose bushes, without the need, as is usually the case with conventional braziers or the like, shovelling up the ashes into a separate container.

Referring to Figures 3 to 5, the burners of the present invention can also be fitted with a grid 40 to separate the burning material from the bottom of the combustion vessel 11,31. This ensures that the ashes from the burned material fall away from the burning material so preventing the ashes from clogging up the perforations 22 above the grid 40 or pockets of air within the mass of burning material.

Typically, the combustion vessel, frame and grid are made from galvanised steel.

Typically, the wheel has a conventional solid or pneumatic tyre.

A further advantage of the present invention is that with the grid 40 in place, or more preferably a second grid especially for the purpose and which may be chromium plated, the burner can be used as a barbecue. The charcoal for a barbecue is placed below the grid 40 and food placed upon the grid. It is thought that, if only for reasons of aesthetics, the embodiment of Figures 2 and 5 will be preferred for this use.

Figure 6 shows an alternative design for the combustion vessel of a burner. The inverted pyramid shape allows any build up of ashes to be directed away to the bottom of the vessel to reduce the incidence of ashes clogging up the air holes.

Claims
