  • Method for controlling combustion device dynamics
    Patent number: 7568349
    Abstract: A method for controlling a combustion dynamics level within a combustion device includes defining a high dynamics operating state at a first fuel split ratio. The first fuel split ratio is a ratio of an amount of fuel supplied to the combustion device through a first fuel line to a total amount of fuel supplied to the combustion device. A low dynamics operating state is defined at a second fuel split ratio different from the first fuel split ratio. The second fuel split ratio is a second ratio of an amount of fuel supplied to the combustion device through the first fuel line to a total amount of fuel supplied to the combustion device. The combustion dynamics level within the combustion device is controlled by periodically switching between the first fuel split ratio and the second fuel split ratio.
