METHOD OF CONTROLLING EMISSIONS OF A GAS TURBINE PLANT AND GAS TURBINE PLANT
A method of controlling emissions of a gas turbine plant (1), including a compressor (7), a combustion chamber (9) and a gas turbine (10), includes detecting the oxygen concentration (S02) in the exhaust gases (QE) of the gas turbine (10) and heating a fuel gas flow (QF) supplied to the combustion chamber (9) as a function of the detected oxygen concentration (S02 ) and of a reference concentration value (S02R; S02R' ).
