Abstract: The present invention relates general to an alcohol burner that uses liquid alcohol as a fuel source and has an increased burn time, controlled combustion and a smaller footprint. In various embodiments, the present invention introduces a system of double stacked baffles with two separate functions. The upper baffle area optimizes controlled combustion, while the lower baffle area optimizes heat transfer from the combustion area down into the fuel storage area. The lower baffle also provides a steady vapor supply to the upper baffle area. By dividing these functions, the burner in accordance with embodiments of the present invention can store fuel vertically, rather than needing to be spread out horizontally. Embodiments of the present invention thus facilitate a wide range of practical configurations for consumer uses not previously possible.

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.

Abstract: A gas range having a cook top and a gas burner assembly connected to a source of gas having a variable flow rate. The burner assembly is positioned in the cook top. The gas burner assembly has a burner body with a gas input, the gas input is in a first flow communication with a first chamber and a second flow communication with a second chamber. Each chamber has at least one port in an exterior wall for flow communication to an area external of the burner body for combustion of the gas. The second flow communication has a tripping pin to deflect flow during high flow conditions and to not deflect flow during low flow conditions. A burner cap is positioned on the burner body.

Abstract: The present invention provides a burner (10) for a heater for combustion of a hydrocarbon liquid. The burner (10) comprises a combustion chamber having a combustion zone (17) for combusting the hydrocarbon liquid and at least one tank portion (13, 15) for containing an amount of the hydrocarbon liquid. The or each tank portion (13, 15) is positioned adjacent the combustion zone (17) and arranged to feed the hydrocarbon liquid into the combustion zone (17). The or each tank portion (13, 15) is at least in part filled with a filling material having a plurality of portions that pass through the interior of the or each tank portion (13, 15).

Abstract: A pot-type burner comprises an open burner having a pot formed by a cylindrical wall defining a column with a bottom wall and an open top, a means for supplying liquid fuel to the vicinity of the bottom wall within the pot, and a first column barrier for restricting the flow of vapor derived from the liquid fuel. The first barrier is spaced axially from the bottom wall in order to form a first chamber with a restricted throat, a second column barrier is spaced axially within the pot, from the first barrier, the second barrier comprising a catalyzer plate extending in a plane normal to the axis of the pot, the catalyzer plate having a central opening, radially extending, spaced apart fins and an annular portion near the first wall of the pot but spaced therefrom to define an annular opening with the first wall.

Abstract: A heater with a fuel vaporizer. The vaporizer has an uptube for carrying fuel and is centrally located within the burner. A cap is located over the uptube. A tubular casing forms an annulus about the uptube and communicates with the cap. Vaporizer fuel is carried upwardly in the uptube and downwardly in the annulus. A zero pressure regulator provides fuel to the burner.

Abstract: A liquid hydrocarbon burner includes a single-walled pot; and a catalytic element placed centrally in the single-walled pot and comprised of an assembly of blades which are arranged concentrically around a vertical axis, which have in axial cross-section a mushroom shape, and which blades have respective upper parts and lower parts with respective weights such that the weight of the lower parts is greater than that of the upper parts. A process for preparing a sheet of chromium inox steel which is catalytically active for hydrocarbon combustion so that it is suitable for making blades for a catalytic element of a liquid hydrocarbon burner includes providing a sheet of chromium inox steel having a silicon content which exceeds 0.40%.+-.0.05 so that the chromium inox steel is refractory to the core; and pickling the sheet of chromium inox steel by treatment thereof with an acid effective to pickle chromium inox steel and render at least the surface thereof catalytically active for hydrocarbon combustion.

Abstract: A vaporizing combustion chamber for a heater running on liquid fuel, in particular a vehicle heater, in which inter alia two pipes disposed concentrically one inside the other form therebetween an annular chamber which is closed at a first end. At the second end, the annular chamber is open and leads into a flame diaphragm which projects radially inwards from the outer pipe and is located at a spacing in front of the inner pipe. At both its ends the inner pipe is substantially open and the opening at the second end is contracted by a concentric baffle edge of a baffle plate. In order to improve the emission values of the combustion chamber exhaust gas and reduce combustion noises both when the combustion chamber is disposed horizontally and when it is disposed vertically, the opening in the flame diaphragm is eccentric to the opening, in the inner pipe, formed by the baffle edge of the baffle plate.

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.

Abstract: A burner system, for example at a heating unit, comprising a burner of evaporation type for liquid fuel, for example Diesel oil, where fuel is intended via an inlet (5) to be supplied into a combustion space, preferably at the bottom (3) thereof, which combustion space preferably is substantially cylindric and open at the end (4) opposite to said bottom (3), and where preferably an ignition member (6), for example a glowing filament, is provided for the initial ignition of evaporated fuel, and where means (9,16,17,18) are provided for the supply of air to the combustion space.

Abstract: A liquid fuel combustion apparatus comprises a combustion cylinder, a fuel reservoir, a housing, a blower and an electrical ignition heater. The reservoir is disposed inside the cylinder to store a liquid fuel supplied from outside of the cylinder. The housing is disposed outside the cylinder to create a space therebetween and has an end wall opposite to an end wall of the cylinder. The blower is disposed outside, and in a spaced apart relation to, the housing and supply air to the space. The heater is supported by the end walls and ignite liquid fuel stored in the reservoir.
