Abstract: A burner for combusting vaporized liquid fuel includes a combustion chamber which is open at an upper end and a side wall which defines air supply openings through which air is delivered into the combustion chamber. A thermally conductive body is disposed in the combustion chamber and extends upwards to the upper end of the chamber. The body enhances the combustion of the fuel within the combustion chamber. A disk-shaped annulus defining gas flow openings is mounted in the combustion chamber and extends radially inwards from the side wall to proximate the body, such that substantially all gas flow past the annulus occurs through the gas flow openings.
