  • Fuel heating via exhaust gas extraction
    Patent number: 8015793
    Abstract: A method and system for heating fuel for a gas turbine engine by using excess heat energy in the engine exhaust gas to heat the fuel and returning the cooled exhaust gas back to the engine exhaust gas stream upstream of an emissions sensor is disclosed. The method and system comprises providing a heat exchanger having an exhaust gas passage and a fuel passage, extracting high temperature exhaust gas from the engine exhaust gas stream and passing the high temperature exhaust gas through the exhaust gas passage. Fuel is passed through the fuel passage where excess heat energy in the high temperature exhaust gas is used to heat the fuel. The temperature of the heated fuel is controlled by controlling the flow of the high temperature exhaust gas through the exhaust gas passage.
