Abstract
In a method for operating a gas turbine, NOx is removed from the exhaust gases of the gas turbine by means of a selective catalysis device with the addition of NH3. The method achieves an extremely low NOx content while simultaneously achieving economic consumption of NH3 and avoiding NH3 in the exhaust gas by maintaining the NOx content of the exhaust gas at a constant level via a regulated return of a portion of the exhaust gas in varying operating conditions of the gas turbine, and by adjusting the addition of the NH3 in the selective catalysis device to the constant NOx level.
