A method can protect a gas turbine engine (), which includes a compressor (), a combustor (), and a turbine (), against high dynamical process values, especially in combustor/flame pulsations. Effective protection against high dynamical process values, especially in combustor/flame pulsations, can be achieved by:

Method for protecting a gas turbine engine against high dynamical process values and gas turbine engine for conducting the method

A combustion chamber is provided and includes a combustion device and a supply circuit arranged to feed fuel at a plurality of locations of the combustion device. The supply circuit includes manifolds collecting fuel to be distributed among at least some of the locations, ducts extending from the manifolds and feeding the locations. Some of the ducts carry valves having a plurality of predetermined working positions, each working position corresponding to a different fuel flow through the valve.
