The fuel supply system (9) includes an auxiliary fuel valve (23) fluidly coupled between the fuel supply line (17) and at least a group of associated burners (18). The control unit (10) is further configured to control the fuel flowrate (M2) using the auxiliary fuel valve (23) in a second load range (LR2) from the threshold partial load (LTH) to a minimum load (ML).",
