The carburetor is turned inalarm at a temperature of about 250 C where the oil is evaporated at sufficient pressure to maintain and constantly burning flame. The oil of the continuous pressure chamber exiting through carburetor jets until it reaches the speed of sound (300 m / s). This phenomenon inalarm causes the lamp has a 'hissing' sound characteristic. Lamp some versions incorporate a small gauge for checking the pressure of the tank. The maximum speed of air and oil vapor is reached in the combustion chamber in the area called 'Glühkörper' the Glühkörper is a kind of synthetic silk fabric inalarm made with various salts, this fabric is combusted in the first operation the lamp until it turns to ashes.
