    摘要: The invention relates to a premix burner with high flame stability for use in a heat producer, preferably in the combustion chamber of a gas turbine. Modern lean operated premix burners make possible very low pollutant emissions, but sometimes operate very close to the extinction limit. To increase the stability of the lean premix combustion by increasing the distance between the flame temperature and the extinction limit temperature, it is proposed according to the invention to arrange a downstream combustion gas mixing section (300) for the burner, which mixing section (300) projects at least partially into the combustion chamber (50) and enables combustion gases from the combustion chamber (50) access to the fuel/air mixture (144) by means of combustion gas inlet openings (311). The added combustion gases (145) are mixed with the fuel/air mixture (144), and in this manner increase its temperature. This increase in temperature results in a significant increase in the flame speed, as a consequence of which the extent of the flame front (123) and the extinction limit temperature of the burner decrease.

    摘要: 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.
