Abstract
A portable alcohol burner is designed to use ethanol as a fuel for indoor/outdoor settings. The burner has a fuel chamber filled with ceramic fiber filler permeated with alcohol. A perforated baffle cage is fitted in the housing and is completely surrounded by the filler material. As alcohol vapors escape from the fuel chamber and rise through the perforations in the baffle cage they can be ignited to create a desired pleasing flame pattern.
Claims48
An alcohol burner assembly, comprising:
- a hollow housing having a fuel chamber defined by a closed bottom plate, a continuous upright sidewall secured to the bottom plate, and a top plate resting on said upright sidewall, said top plate being provided with an open portion;
- a baffle cage mounted in the fuel chamber and extending downwardly into the fuel chamber below the top plate, said baffle cage being provided with a plurality of openings and an open top substantially aligned with the open portion of the top plate;
- and
- a porous filler deposited in the fuel chamber in a surrounding relationship to the baffle cage, said filler being permeated with liquid alcohol.
An alcohol burner assembly, comprising:
- a hollow housing having a generally rectangular fuel chamber defined by a closed bottom plate, a continuous upright sidewall secured to the bottom plate and extending upwardly therefrom, and a top plate resting on said upright sidewall, said top plate being provided with a generally rectangular opening;
- a substantially rectangular baffle cage mounted in the fuel chamber to extend downwardly into the fuel chamber below the top plate, said baffle cage having a generally U-shaped cross section and being provided with a plurality of perforations along bottom and sides of the baffle cage and an open top substantially aligned with the rectangular opening of the top plate;
- a generally rectangular baffle cover configured for sliding engagement with the top plate, said baffle cover being configured to move between an open position away from the rectangular opening and a closed position extending over the rectangular opening and the baffle cage;
- and
- a ceramic fiber filler deposited in the fuel chamber in a surrounding relationship to the baffle cage, said filler being permeated with liquid alcohol.
A method of producing a generally rectangular flame pattern in an alcohol burner, comprising the following steps:
- providing a hollow housing having a fuel chamber defined by a closed bottom plate, a continuous upright sidewall secured to the bottom plate and extending upwardly therefrom, and a top plate resting on said upright sidewall, said top plate being provided with a generally rectangular opening;
- providing a substantially rectangular baffle cage mounted in the fuel chamber and extending to about one-half depth of the fuel chamber, said baffle cage being provided with a plurality of perforations in a bottom and side walls of the baffle cage and an open top substantially aligned with the rectangular opening of the top plate;
- providing a ceramic fiber filler deposited in the fuel chamber in a surrounding relationship to the baffle cage, said filler being permeated with liquid alcohol;
- allowing alcohol vapor to escape from the fuel chamber into the baffle cage and admix with air;
- and
- igniting the alcohol vapor in the baffle cage, thereby creating a generally rectangular flame pattern escaping the baffle cage.
