A gas turbine combustor apparatus comprising plural combustors and plural fuel supply systems realizes a combustion of a lean and uniform pre-mixture in each of the combustors to thereby enable to reduce NOx generation. Flow regulating valves 29, 30 are provided in fuel supply systems 23, 24, respectively, that supply combustors 25, 26 with fuel. Pressure gauges 31, 32 are provided in the fuel supply systems 23, 24, respectively, in front of inlets of the combustors 25. 26. The flow regulating valves 29, 30 are controlled so that pressures measured by the pressure gauges 31, 32 become the same.

Un appareil de chambres de combution de turbine à gaz comprenant une pluralité de chambres de combustion et une pluralité de systèmes d'alimentation en carburant permet de réaliser une combustion d'un pré-mélange pauvre et uniforme dans chacune des chambres de combustion pour ainsi réduire les émissions de NOx. Des soupapes de régulation de débit 29, 30 sont prévues dans les systèmes d'alimentation en carburant 23, 24, respectivement, qui approvisionnent en carburant les chambres de combustion 25, 26. Des jauges de pression 31, 32 sont prévues dans les systèmes d'alimentation en carburant 23, 24, respectivement, en face des entrées des chambres de combustion 25, 26. Les soupapes de régulation de débit 29, 30 sont commandées de telle sorte que les pressions mesurées par les jauges de pression 31, 32 deviennent les mêmes.
