SVEA 123 Vintage Brass Camp Stove Made In Sweden

The Swedish-made Svea 123 is a small liquid-fuel (naphtha, commonly referred to as white gas or Coleman fuel) pressurized-burner camping stove that traces its origins to designs first pioneered in the late 19th century.To light the stove, the fuel tank must first be pre-heated and pressurized by lighting a small amount of fuel poured into the primer pan or spirit cup (a small well) on top of the tank at the base of the vaporizer (the vertical stem connecting the fuel tank to the burner...). Alternatively, the primer pan can be filled directly from the fuel tank by opening the control valve and warming the fuel tank by holding it in one’s hands. This will increase the pressure in the fuel tank and force a small amount of fuel to trickle out of the burner jet and into the primer pan.[18] The control valve must then be closed before lighting the priming fuel so as to allow pressure to build up in the tank when the exterior fuel begins to heat the tank and the fuel within. The tank can also be pressurized by an optional pump that may be attached to the filler cap, but this is generally not necessary except in extreme cold. Fuel from the tank is fed by a cotton wick inside the tank to the base of the vaporizer. The heat and pressure created by the priming flame vaporizes the fuel inside the vaporizer. When the priming flame is nearly burnt out, the control valve is opened by turning the adjusting key. This allows the vaporized fuel to flow under pressure through the burner jet (a small opening at the base of the burner), where it mixes with oxygen and burns with a blue flame. Adjusting the flow of the vaporized fuel that is forced through the burner jet controls the flame size and heat output. The control valve (a spindle) is threaded in the vaporizer's housing, and as it is opened (by turning the adjusting key) it opens like a faucet (counter-clockwise to open and clockwise to close) and the vaporized fuel flows through the burner jet. Closing the spindle closes the fuel supply. A small plate on the top of the burner (a flame spreader) spreads the flame outwards. The heat generated in the burner and vaporizer maintains the internal pressure in the fuel tank
