| 20120167546 | COMBINED-CYCLE POWER PLANT - A method involves operating a combined-cycle power plant ( | 07-05-2012 |
| 20120216547 | POWER PLANT FOR CO2 CAPTURE - An exemplary fossil fuel fired power plant is disclosed with minimum impact of the CO2 capture system on a power part of the plant. A power plant is disclosed which is ready for the retrofit of a CO2 capture plant, and a method is disclosed for retrofitting an existing plant into a power plant with CO2 capture. A power plant part is disclosed which can provide steam and power to operate CO2 capture system, and provide a CO2 capture system, which has the capacity to remove CO2 from flue gas flow of the power part, and of the additional power plant part. | 08-30-2012 |
| 20120227372 | POWER PLANT FOR CO2 CAPTURE - A power plant is provided including a steam power plant and/or a combined cycle power plant. A water steam cycle of the plant includes two steam turbine arrangements; the first turbine arrangement includes steam turbines with at least two pressure levels and a second turbine arrangement having at least one back pressure turbine configured to expand steam to the supply pressure of a CO2 capture system. A method for operating the plant includes operating the first steam turbine arrangement to produce power during all steady state operating points of the steam cycle and at least a part of the second steam turbine arrangement is bypassed to the system and/or is operated to produce power and to release low-pressure steam to the system when the system is in operation. Both steam turbine arrangements are operated using all available steam to produce power when the system is not in operation. | 09-13-2012 |
| 20120240871 | METHOD AND CONFIGURATION TO REDUCE FATIGUE IN STEAM DRUMS - A heat recovery steam generator that includes a first steam drum for receiving a flow of water and steam from an evaporator. The first steam drum is adapted to provide the flow of water and steam to a second steam drum. The second steam drum is in fluid communication with the first steam drum and receives the flow of water and steam from the first steam drum and separates steam from the flow of water and steam to form a separated steam. There is a steam flow outlet positioned in the second steam drum, the steam flow outlet adapted to release the separated steam from the second steam drum. | 09-27-2012 |
