20150113939 | COMBINED CYCLE POWER PLANT WITH IMPROVED EFFICIENCY - A CCPP includes a gas turbine, a HRSG, a steam turbine a flash tank and first and second supply lines. The gas turbine, the HRSG and the steam turbine are interconnected to generate power. The gas turbine may include an air preheating system to preheat the air supplied in the gas turbine to enable expedite combustion therein. The flash tank is fluidically connected at a cold end of the HRSG to extract waste hot water from the cold end. Further, the first supply line is configured to interconnect the flash tank and the steam turbine to supply of flash steam to the steam turbine. Furthermore, the second supply line is configured to interconnect the flash tank and the air preheating system to supply hot flash condensate thereto. | 04-30-2015 |
20150114319 | FEEDWATER PREHEATING SYSTEM AND METHOD - The feedwater preheating system includes a feedwater tank and a constant volume recirculation pump. The feedwater tank is adapted to store the feedwater. The feedwater tank includes feed and return lines. The feed line is adapted to feed the feedwater to the HRSG, and the return line enables returning of the feedwater into the feedwater tank. The return line precludes a control valve, and is configured to the feedwater tank to reduce component loss while feedwater recirculation. The constant volume recirculation pump is configured in the feed line to recirculate the feedwater between the HRSG and the feedwater tank. The pump is capable of recirculating the feedwater at constant speed and volume to reduce heat loss while feedwater recirculation, as against the prior art feedwater preheating systems. | 04-30-2015 |

20110232295 | METHOD FOR OPERATION OF AN INTEGRATED SOLAR COMBINED-CYCLE POWER STATION, AND A SOLAR COMBINED-CYCLE POWER STATION FOR CARRYING OUT THIS METHOD - A method is provided for operation of an integrated solar combined-cycle power station. The power station includes a water/steam circuit having a steam turbine and a heat recovery steam generator through which hot exhaust gases from a gas turbine flow. The water/steam circuit is additionally supplied with heat from a solar array. In such a method, an optimum cost-benefit relationship is achieved in that the water/steam circuit is designed only for the full load on the gas turbine, and in that, when feeding additional power from the solar array into the water/steam circuit, the load on the gas turbine is reduced, on the basis of the power additionally fed in from the solar array, to such an extent that the total output power of the integrated solar combined-cycle power station remains substantially constant. | 09-29-2011 |
