  • Heat recovery steam generator with electrical heater system and method
    Patent number: 11181041
    Abstract: A system includes a turbine system that contains a heat recovery steam generator (HRSG) having a flow path that receives an exhaust gas, and having a fluid path that receives a fluid. The fluid path is adjacent to the flow path such that the fluid is heated by the exhaust gas. The HRSG includes an electrical heater that provides heat to the fluid path during a start-up mode of the HRSG, during a shutdown mode of the HRSG, or both.
    Type: Grant
    Filed: February 2, 2017
    Date of Patent: November 23, 2021
    Assignee: General Electric Company
    Inventors: Gordon Raymond Smith, Allen Michael Pfeffer, Robert John Gdaniec

  • Power plant with COcapture and compression
    Patent number: 8346394
    Abstract: Power plant characteristics are operated in a flexible manner by controlling the power consumption of a CO2 capture and compression system. The impact of CO2 capture and compression on the capacity of a power plant can be minimized to maximize the electric power the plant can deliver to the power grid and the impact of CO2 capture and compression on the average plant efficiency can be reduced, by an operating method and a power plant, in which the power consumption of the CO2 capture system is used to control the net output of the plant.
