Control method for controlling the supply of fuel to a gas turbine plant and gas turbine plant

摘要

A control method for controlling the supply of fuel to a gas turbine plant (1) provided with a gas turbine (6) and a combustion chamber (4) supplied with a fuel/oxidizer mixture, includes the steps of:
- at the exhaust (12) of the gas turbine (6), detecting at least a first parameter related to the unburned fuel concentration (UHC);
- at the exhaust (12) of the gas turbine (6,) detecting at least a second parameter related to the specific energy produced by the combustion (CO);
- calculating a fuel flow rate (Q TOT ) to be supplied to the combustion chamber (4) on the basis of the first parameter (UHC) and of the second parameter (CO).
