Combustion device with pulsed fuel split

It is described a combustion device control unit and a combustion device, e.g. a gas turbine, which determine on the basis of at least one operating parameter whether the combustion device is in a predefined operating stage. In response hereto, there is generated 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.
