Abstract
A method for running up a gas turbine plant ( ) is disclosed. In the method, a fuel ( ) is injected into the combustion chamber ( ) via a plurality of pilot burners ( ) and premix burners ( ). During the start-up and in a lower load range, the combustion chamber ( ) is operated in the pilot mode, and, at a specific time point, the combustion chamber ( ) is changed over from the pilot mode to the premix mode. The changeover time point from the pilot mode to the premix mode depends on a variable changeover temperature (T ), and this changeover temperature (T ) is determined from pulsations occurring in the flame of the combustion chamber ( ).
