Abstract
A premix burner arrangement with catalytic combustion provides a fuel/air mixture to a combustion chamber of a gas turbine arrangement. The premix burner arrangement includes a premix burner, at least one fuel addition unit, and air inlet openings arranged in such a way that at least one of gaseous and liquid fuel can be mixed with combustion inlet air inside the premix burner to form a fuel/air mixture. The fuel/air mixture exits from the premix burner downstream in the direction towards a combustion chamber positioned after the premix burner arrangement and can be ignited inside the combustion chamber. A catalyzer unit is provided before the entrance of the fuel/air mixture into the combustion chamber. Part of the fuel/air mixture can be introduced into and passed through the catalyzer unit before the catalyzed part of the fuel/air mixture flows together with the remaining portion of the fuel/air mixture into the combustion chamber.
