METHOD AND APPARATUS FOR OPERATING A COMBUSTION DEVICE

摘要

The present invention generally relates to the field of combustion technology related to gas turbines. More in particular, the present invention refers to a method for operating a combustion device. Advantageously, by means of the invention a pulsation protective load shedding (PLS) is avoided by adjusting the parameter É (water/oil ratio) in case of too high combustion pulsation levels from the standard operation set point. This implies that the dynamic pulsation control logic (P.C.L.) is activated in case the high frequency pulsation level exceeds a predetermined threshold value and a control unit adjusts the É, preferably in a stepwise manner, until acceptable and optimum pulsation levels are reached or a maximum reduction of the É is performed
