  • Combined fuel and air staged power generation system
    Patent number: 8733109
    Abstract: A method and apparatus for generation of electric power employing fuel and air staging in which a first stage gas turbine and a second stage partial oxidation gas turbine power operated in parallel. A first portion of fuel and oxidant are provided to the first stage gas turbine which generates a first portion of electric power and a hot oxidant. A second portion of fuel and oxidant are provided to the second stage partial oxidation gas turbine which generates a second portion of electric power and a hot syngas. The hot oxidant and the hot syngas are provided to a bottoming cycle employing a fuel-fired boiler by which a third portion of electric power is generated.
    Type: Grant
    Filed: March 29, 2010
    Date of Patent: May 27, 2014
    Assignee: Gas Technology Institute
    Inventors: Iosif K. Rabovitser, John M. Pratapas, Dmitri Boulanov
  • Co-production of fuels, chemicals and electric power using gas turbines
    Patent number: 8268896
    Abstract: A method and system for co-production of electric power, fuel, and chemicals in which a synthesis gas at a first pressure is expanded using a stand-alone mechanical expander or a partial oxidation gas turbine, simultaneously producing electric power and an expanded synthesis gas at a second pressure after which the expanded synthesis gas is converted to a fuel and/or a chemical.
