Abstract: A burner apparatus is specially designed for vaporized fuels such as alcohol vapor for use by campers, aboard small boats, in vans, and the like. Extremely efficient combustion is achieved by an annular air/fuel mixer plate with a plurality of circular openings facing upwardly positioned above an annular vapor generator member having an annular cavity with fuel outlet ports passing through the top wall of the cavity in positions spaced vertically below and in axial alignment with the circular openings in the air/fuel mixer plate, respectively. A liquid fuel line communicates with the interior portion of the cavity for introducing liquid fuel therein and once combustion has started, the fuel is vaporized to pass out the fuel openings.
