  • Patent number: 5307799
    Abstract: A container defining an outer housing includes a base, a surrounding side wall structure extending upwardly from the base, and a top wall having a central opening therethrough exposing an interior chamber containing a liquid fuel supply, including diethylene glycol and an isoparaffin mixture. A fibrous material filled within the interior chamber is structured and disposed to hold and stabilize the diethylene glycol which fills pockets throughout the fibrous material to form a stabilized gel-like mass. An ignitor cord extending upwardly from the base within the interior chamber and through the central opening delivers the isoparaffin mixture by capillary action from a bottom of the interior chamber to an exterior, exposed portion of the ignitor cord to facilitate initial igniting thereof and subsequent igniting of the diethylene glycol on an upper exposed surface of the fibrous material.

  • Patent number: 5098283
    Abstract: The invention provides a combustion device such as a stove which may include a pressurized fuel mixture, such as an aerosol container containing alcohol and a propellant which may comprise a normally gaseous hydrocarbon, such as a liquified petroleum gas. The propellant and air are fed to a combustion zone as a combustion mixture, which is combusted therein in a cold start period to pre-heat the liquid fuel and vaporize it. When the liquid fuel is vaporized by the heat provided by combusting the propellant gas, combustion is continued by combusting the vaporized liquid, e.g., alcohol, fuel. The pressurized fuel composition may comprise a major proportion of alcohol together with a minor proportion of the hydrocarbon propellant starter fuel. The method therefore includes carrying out an initial, cold-start phase of combustion utilizing the propellant as fuel, and a subsequent stage of combustion utilizing the vaporized liquid fuel.

  • Patent number: 4793321
    Abstract: The present invention is drawn to a self-priming alcohol stove comprising a burner cup with a base and side walls for storage of liquid alcohol, a main burner attached to the burner cup, a start-up burner, and a heat transfer unit to transfer heat from the main burner and/or the start-up burner to a quantity of alcohol held by transfer unit within the burner cup at a location distal from the side walls and the base. The vaporized alcohol passes to the main burner and is ignited by flames from the start-up burner. More alcohol is then continuously absorbed from the burner cup by the wick between the concentric, cylindrical walls to maintain the main burner flame. Operation of the main burner substantially deprives the start-up burner of oxygen so that heat from the main burner vaporizes alcohol absorbed between the concentric walls.
