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.

Abstract: Flow of liquid fuel to a vaporization tube of a heating device is controlled by a vertically adjustable float valve, with the vertical height of a surface level of the fuel in a float valve chamber being set to correspond to a desired operating level of the liquid fuel in the vaporization tube. Liquid fuel is permitted to free-flow from the float valve chamber to the lower end of the vertical vaporization tube without metering, the rate of flow and the level of the fuel in the vaporization tube being determined solely by the hydraulic head created by the surface level of the fuel in the float valve chamber. Raising of the float valve chamber produces a corresponding raising of the level of the fuel in the vaporization tube to increase the tube inner surface area which is contacted or wetted by the fuel in the tube, thus causing an increase in the rate of vaporization and a corresponding increase in heat output of the heating device.
