Abstract: A fuel control mechanism for a liquid fuel burner includes a fuel regulating valve which is responsive to flow of liquid fuel through a fuel feed tube for movement between a starting position and a running position. When a fuel control valve for the burner is opened, flow of liquid fuel through the fuel feed tube moves the fuel regulating valve to a starting position in which the fuel regulating valve restricts flow of fuel through a fuel inlet. Air is thereby drawn through an air inlet and mixes with the fuel. After the burner is started and liquid fuel is vaporized within the generator, flow of fuel through the fuel feed tube slows, and the fuel regulating valve falls by virtue of its weight to the running position in which the fuel regulating valve does not restrict flow of fuel through the fuel inlet. Air flow through the air inlet is thereby discontinued, and only liquid fuel flows through the fuel feed tube.

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.

The net structure is to prevent any displacement or deformation of the gas flow controlling filter, which displacement or deformation would be otherwise caused if the filter is exposed to an increased gas pressure, and then the valve could not keep the gas flow rate constant, and hence the flame length constant and stable. The filter can be put in position simply by push-fitting an associated annular spacer in the recess.

The rise of the surrounding temperature will cause the membrane to bend yieldingly upwards to cover the inside of the porous object, thereby preventing the increase of the gas flow passing through the porous object over a predetermined flow rate.
