Abstract
A method of operating a control unit for controlling at least two different input fuel flows to a combustion device, e.g. a gas turbine includes the step of determining on the basis of at least one operating parameter whether the combustion device is in a predefined operating stage. In response hereto, generating a control signal configured for setting a ratio of at least two different input fuel flows to a predetermined value (psc1, psc3) for a predetermined time (dt) in case the combustion device is in the predefined operating stage.
Claims9
A method for operating a control unit for controlling at least two different input fuel flows to a combustion device, comprising:
- receiving at least one operating parameter through a control input of the control unit;
- determining whether the combustion device is operated in a predefined operating stage based on the at least one operating parameter;
- and
- generating a control signal for setting a ratio of the at least two different input fuel flows to a predetermined value for a predetermined time in case the combustion device is in the predefined operating stage,
- wherein the ratio of the at least two different input fuel flows is set to the predetermined value by changing the ratio of the at least two different input fuel flows from a present value to the predetermined value in a stepwise manner, and
- wherein the ratio of the at least two different input fuel flows is set to the predetermined value for the predetermined time comprising a pulse shaped temporal change of the ratio of the at least two different input fuel flows.
