<p>Method for heating a fluid, in particular a fluid which is not electrical conductive, where a rotor body (10) which is arranged in a chamber for absorption of the fluid, is rotated with a generally vertical shaft (11). A voltage is applied to a rod shaped electrode (16) which is arranged centrally in a rotor chamber (12) and to an electrode at the bottom (13) of the rotor chamber, for creation of a flame arc, so that a flow of the fluid passing the flame arc is created. The length (L) of the flame arc is held generally stable, preferably constant by controlling the position of the rod shaped electrode (16). The fluid is made enter the rotor chamber (12) so that it is kept outside the flame arc, and that the fluid is provided to flow through the rotor chamber (12).</p> |
