A portable liquid fuel stove is disclosed herein which is particularly suited for cooking out of doors. The stove includes an annular shaped, cast fuel tank with a central opening having circumferentially spaced depending bottom ribs and upstanding top ribs both preferably cast with the fuel tank to form an integral unit. A control valve assembly preferably extends radially inwardly from the tank, and a fuel vaporizing section extends transverse to the valve assembly in axial alignment within the central opening in a lower portion of the tank. Vaporized fuel is passed from the fuel vaporizing section through an orifice disposed within the central opening in a lower portion of the tank to provide a stream of vaporized fuel. A burner cup in the central opening is substantially confined within the vertical extent of the tank to provide a mixing chamber. The flame produced heats the tank to pressurize the tank to force the fuel from the tank into the vaporizing chamber and vaporize the fuel in the vaporizing chamber for continuous burning.
