  1. 21. Flexible Ignition System for a Gas Turbine

    University essay from KTH/Kraft- och värmeteknologi

    Author : Anton Berg; [2012]
    Keywords : Gas turbine; ignition; methane; propane; CO2; N2; ignition energy; ignition delay time;

    Abstract : Siemens Industrial Turbomachinery AB produce five gas turbines models. The SGT-700 can currently only start on gases which contain low amounts of inert gases. It is therefore of interest to widen the fuel range which the SGT-700, as well as other gas turbines, can start on. READ MORE

  3. 22. Weld Analysis in Combustion Chambers Subjected to Thermo-Mechanical Fatigue Load Conditions

    University essay from Hållfasthetslära

    Author : Johnny Johansson; [2011]
    Keywords : Weld; analysis; TMF; fatigue;

    Abstract : At cyclic operation of gas turbines, components are subjected to thermo-mechanical fatigue (TMF) due to the high temperature gradients that arises. In this thesis life assessment of welds in combustion chambers are at focus. READ MORE
