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.

摘要： A method is disclosed for operating a gas turbine power plant having a gas turbine, a heat recovery steam generator and an flue gas splitter which splits flue gases into a first flue gas flow for recirculation into an inlet flow of the gas turbine and into a second flue gas flow for discharge to an environment. An oxygen-depleted gas can be used in an open cooling system for cooling hot gas parts of the gas turbine. A split compressor intake can be provided for separate feed of recirculated flue gas and fresh air into a compressor intake. Compressor blades can include a separating band which blocks intermixing of recirculated flue gas and fresh air during compression.
