Abstract
Described is a premix burner arrangement as well as a method for operating the same, comprising a pilot fuel feeding means for operating a combustion chamber of a gas turbine arrangement, a premix burner, wherein at least one fuel addition unit as well as supply air openings have been provided in such a way that gaseous and/or liquid fuel can be mixed with combustion supply air inside the premix burner and form a fuel/air mixture, which exits from the premix burner downstream in the direction towards the combustion chamber positioned after the premix burner arrangement and which can be ignited inside the combustion chamber in the form of a spatially largely stationary flame.The invention is characterized in that outside of the premix burner, a catalyzer unit is provided, through which the pilot fuel feeding is performed in such a way that a pilot fuel/air mixture flows through the catalyzer unit and can be converted in it at least in part catalytically, and flows as a mass flow that stabilizes the flame into the combustion chamber.
