NOVELTY - The method for plasma-reforming of fuel such as kerosine, comprises supplying fuel to inlet of an expansion nozzle (3) through a pipeline (7), feeding energy from an energy source (9) over a wave guide to generate a plasma state in the expansion nozzle, supplying further fuel through a fuel nozzle (13) in the emerging plasma flame to split the fuel in to heat into components such as carbon monoxide, carbon and hydrogen, and expanding the plasma flame with high speed in a combustion chamber (5). Arc-discharge- or microwave plasma is used to generate the plasma state.    USE - Method for plasma-reforming of fuel such as kerosine for different types of turbine, combustion motors or fuel cells.    ADVANTAGE - The method ensures plasma-reforming of fuel with low equipment cost by reducing emission of nitric oxide.    DETAILED DESCRIPTION - The method for plasma-reforming of fuel such as kerosine, comprises supplying fuel to inlet of an expansion nozzle (3) through a pipeline (7), feeding energy from an energy source (9) over a wave guide to generate a plasma state in the expansion nozzle, supplying further fuel through a fuel nozzle (13) in the emerging plasma flame to split the fuel in to heat into components such as carbon monoxide, carbon and hydrogen, and expanding the plasma flame with high speed in a combustion chamber (5). Thermal high pressure plasma such as arc-discharge- or microwave plasma is used to generate the plasma state. The suction of air from air nozzle necessary for the combustion is carried out without additional arrangements by the expansion of plasma-flame with high speed in the combustion chamber. The combustion is carried out in the combustion chamber at 1000 degrees C by extreme excess air. An INDEPENDENT CLAIM is included for a device for plasma-reforming of fuel such as kerosine.
