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.Type: GrantFiled: February 8, 2021Date of Patent: May 23, 2023Assignee: GENERAL ELECTRIC TECHNOLOGY GMBHInventors: Klara Berg, Mariah Couzzi-Carneiro, Paul Drouvot, Torbjörn Stenström

Patent number: 10393369Abstract: A preheating system for preheating fluid medium to be fed into the HRSG is disclosed. The system includes a feed line and a recirculation line. The feed line is adapted to feed the fluid medium to a Low Pressure Economizer (LPE) of the HRSG. The feed line is adapted to be adjoined to an inlet of the LPE, and an outlet of the LPE enables therefrom the flow of the fluid medium in further portion of the HRSG. The recirculation line is adapted to be connected between the outlet and the inlet of the LPE, in parallel to LPE to recirculate the fluid medium to the LPE. A particular method of preheating using such a system is equally disclosed.Type: GrantFiled: March 27, 2015Date of Patent: August 27, 2019Assignee: General Electric CompanyInventors: Paul Drouvot, Torbjorn Stenstrom, Klara Berg

Patent number: 10006313Abstract: The invention refers to a CCPP comprising a gas turbine, a water steam cycle with a steam turbine and a HRSG with at least two pressure levels, and a fuel preheater for preheating the fuel of the gas turbine. The fuel preheater includes a first heat exchanger for preheating the fuel to a first elevated temperature, which is connected to a feed water line from a pressure level of the HRSG, which is below the highest HRSG pressure level, and a second heat exchanger for further preheating the fuel gas to a second elevated temperature, which is connected to the high pressure feed water with the highest pressure level of the HRSG. The disclosure further refers to a method for operating a CCPP with such a fuel preheater.Type: GrantFiled: June 27, 2014Date of Patent: June 26, 2018Assignee: GENERAL ELECTRIC TECHNOLOGY GMBHInventors: Paul Drouvot, François Droux, Klara Berg
