摘要： A combustion device includes a plurality of mixing devices into which a fluid containing oxygen and a fuel are introduced and mixed to form a mixture. The combustion device also includes a combustion chamber in which the mixture formed in the mixing devices is burnt. Each mixing device has a conical body with a lance projecting into the conical body, where the fuel is injectable into the conical body. Tips of the lances of different mixing devices have different distances from corresponding open ends of the respective conical bodies.

摘要： An exemplary method for the operation of a CCPP with flue gas recirculation to reduce NOx emissions and/or to increase the CO2 concentration in the flue gases to facilitate CO2 capture from the flue gases as well as a plant designed to operate is disclosed. To allow a high flue gas recirculation ration (rFRG) an imposed combustion inhomogeneity ratio (ri) is used for flame stabilization. The imposed combustion inhomogeneity ratio (ri) is controlled as function of the flue gas recirculation rate (rFRG) and/or combustion pressure. Oxygen or oxygen enriched air to the gas turbine inlet gases or to the combustor is admixed to enhance operatability.

摘要： A gas turbine (1) includes a compressor (2) that feeds an oxidizer to one or more combustion devices (3, 5) in which fuel is injected and is combusted to generate hot gases that are expanded in a turbine (4, 6). The flue gases discharged from the turbine (4, 6) are partially recirculated into the compressor (2). The fuel is a gaseous fuel that is injected into the combustion devices (3, 5) via two or more stages (20, 22, 23). One of the stages is a pilot stage (20) in which the fuel is injected along a longitudinal axis (21) of the combustion device (3, 5) or an axis parallel thereto.
