Abstract
In a fuel lance for spraying liquid and/or gaseous fuels into a combustion chamber, which fuel lance is part of a secondary or tertiary burner, around which a hot-gas jet flows in a main flow direction, and comprises a liquid-fuel passage for supplying liquid fuel and first means for spraying the liquid fuel from the liquid-fuel passage into the combustion chamber, operation characterized by reduced addition of water is made possible owing to the fact that the first means comprise a liquid-fuel nozzle, which sprays the liquid fuel essentially parallel to the main flow direction as a plain jet into the combustion chamber.
