GAS TURBINE BURNER AND METHOD OF OPERATING A GAS TURBINE BURNER

摘要

The invention is based on a gas turbine burner (4) comprising a combustion zone (6) for burning a mixture consisting of combustion exhaust gas (10) to which fuel gas (8) is added, and comprising a fuel intermixing arrangement (18) having a fuel nozzle (20, 34, 48) for spraying the fuel gas (8) into the combustion exhaust gas (10). In order to achieve low-pollutant and uniform combustion, it is proposed that the fuel intermixing arrangement (18) be designed for spraying the fuel gas (8) into the combustion exhaust gas (10) at at least 0.2 times the speed of sound.
