20110289899 | COMBINED CYCLE POWER PLANT WITH FLUE GAS RECIRCULATION - 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. | 12-01-2011 |
20120227440 | System And Process For The Physical Absorption of Carbon Dioxide From a Flue Gas Stream - Disclosed herein is a system comprising a first heat exchanger; the first heat exchanger being operative to reduce a temperature of a carbon dioxide rich flue gas stream to about −100 to about −60 C; an absorber; the absorber being located downstream of the first heat exchanger; wherein the absorber facilitates contact between the flue gas stream and a solvent to form a carbon dioxide rich solvent stream; the solvent being operative to selectively absorb carbon dioxide over other gases present in the flue gas stream; and a valve; the valve being located downstream of the absorber; the valve being operative to reduce a pressure on the carbon dioxide rich solvent stream to produce carbon dioxide and a lean carbon dioxide solvent stream. | 09-13-2012 |

20120240590 | GAS TURBINE POWER PLANT WITH FLUE GAS RECIRCULATION AND OXYGEN-DEPLETED COOLING GAS - 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. | 09-27-2012 |
20140060064 | METHOD OF INCREASING ELECTRICITY OUTPUT DURING HIGH DEMAND - The present disclosure relates to a method of operating a combined cycle power generating system. The method includes combusting a fuel in a gas turbine, generating electricity and a steam of flue gas, producing a stream of steam in a heat recovery steam generator, producing a stream of concentrated carbon dioxide using an absorption unit and a solvent regeneration unit, forwarding the steam stream to a steam turbine and transferring the heat energy in the stream exiting the steam turbine to the solvent regeneration unit, and a thermal storage unit for storing heat energy. The method also includes operating a thermal storage unit, at least for a period of time, in a heat storing mode, in which a stream of steam from the stream exiting the steam turbine is condensed and transfers heat energy to heat storing means in the thermal storage unit, and operating the thermal storage unit, at least for a period of time, in a heat releasing mode, in which heat energy stored in the thermal storage unit is transferred to the solvent regeneration unit. The present disclosure further relates to a combined cycle power generating system as well as a combined cycle power plant including such a system. | 03-06-2014 |
