Abstract
A method for controlling the combustion in a gas turbine including measuring, with one or more probes situated adjacent to the combustion chamber of the turbine, the amplitude of the pressure oscillations inside the combustion chamber and the persistence time or cycle of the same oscillations, evaluating the behavior under fatigue conditions of the combustion chamber, by constructing the Wohler curve for a certain material which forms the combustion chamber for a predefined combustion frequency and for the amplitude and cycle values of the pressure oscillations measured, measuring the cumulative damage to the combustion chamber during functioning under fatigue conditions of the turbine using the Palmgren-Miner hypothesis and exerting protection actions of the turbine if the cumulative damage value measured is exceeded.
