    • The invention is directed to a combustion apparatus, particularly a gas turbine engine, comprising: a fuel supply line (27) to the combustion apparatus for providing an overall fuel supply to the combustion apparatus; at least one burner (20) including a plurality of fuel supply lines (24, 25) to the at least one burner (20), the supply of fuel in the plurality of fuel supply lines (24, 25) to the at least one burner (20) corresponding to the overall fuel supply in the fuel supply line (27) to the apparatus; a combustion volume (23) associated with the at least one burner (20); a temperature sensor (32) located in the apparatus such as to be able to convey temperature information relating to a part (31) of the apparatus which is to be protected against overheating; a pressure sensor (33) such as to be able to convey pressure information representing pressure within the combustion volume (23); and a control arrangement (36). The control arrangement (36) is arranged to vary the fuel supplies to one or more of the at least one burner (20) based on the temperature information and on the pressure information and on a further information, the further information being indicative for a progress over time for a signal for a time span defined by a time information, such as to maintain the temperature of said part (31) to be protected below a predetermined maximum temperature limit, and such as to keep the pressure variations within the combustion volume (23) below a predetermined maximum pressure variation limit, while keeping the overall fuel supply in the fuel supply line (27) to the apparatus substantially constant.
