摘要
In a method for reducing the NOx emissions from a burner arrangement comprising a plurality of burners (B1, . . . , Bn), in particular in a gas turbine, which burners (B1, . . . , Bn) are operated in parallel and each burner supplied fuel by means of combustion air to form a flame (F1, . . . , Fn), an effective drop is achieved in a simple way by virtue of the fact that at a predetermined time the flame temperatures of individual burners (B1, . . . , Bn) or burner groups or differences between the flame temperatures of individual burners (B1, . . . , Bn) or burner groups are measured directly or indirectly. The fuel supply to those burners or burner groups whose flame temperature exceeds a predetermined value for the flame temperature is selectively throttled in order to homogenize the flame temperatures of the burners (B1, . . . , Bn).
