  1. 16. Experimental Investigation of Fuel Mixing Concepts for 3rd Generation DLE Burners : Evaluation Through Water Rig and Atmospheric Combustion Rig Measurements

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Jonathan Lönning; [2016]
    Nyckelord :;

    Sammanfattning : New Siemens burner concepts thought to produce a more homogeneous air/fuel mix-ture and a better distribution of the fuel over the burner cross section have been evaluated. A homogeneous air/fuel mixture is known to produce the lowest levels of emitted oxides of nitrogen (NOx) which is a main objective for Siemens Industrial Turbomachinery AB (SIT). LÄS MER

  3. 17. Simulation of Gas Channel Temperatures during Transients for SGT-800

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Tobias Johansson; [2016]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Siemens Industrial Turbomachinery has developed dynamic gas turbine models to compute performance parameters such as temperature, pressure, mass flow and power during transients. Results from the current dynamic model correspond to measured data except for gas channel temperatures that change too fast during transients. LÄS MER

  4. 18. Development of a Simulation Methodology for Gas Turbine Combustion

    Magister-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Thommie Nilsson; [2015]
    Nyckelord :combustion; computational fluid dynamics; reactor network; Physics and Astronomy;

    Sammanfattning : The main goal of this thesis was the development and application of a method to construct reactor networks based on pre-calculated flow fields for combustion systems. Computational fluid dynamics (CFD) was used to calculate flow fields for the Sandia piloted jet flame D and a Siemens SGT-800 gas turbine burner rig. LÄS MER

  5. 19. Prediction of ignition limits with respect to fuel fraction of inert gases. : Evaluation of cost effective CFD-method using cold flow simulations

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Johan Sjölander; [2015]
    Nyckelord :Combustion; gas turbines; CFD;

    Sammanfattning : Improving fuel flexibility for gas turbines is one advantageous property on the market. It may lead to increased feasibility by potential customers and thereby give increased competiveness for production and retail companies of gas turbines such as Siemens Industrial Turbomachinery in Finspång.

  7. 20. Exhaust gas recirculation on twin shaft gas turbines - A study to improve part load performance

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Benjamin Mattsson; [2015]
    Nyckelord :Exhaust gas recirculation; EGR; FGR; Twin shaft gas turbine; Part load; Emissions; SGT-750; IPSEpro; SimTech; Technology and Engineering;

    Sammanfattning : By recirculating exhaust gases to the gas turbine inlet a temperature rise and hence, a density reduction, is achieved at the compressor inlet. For a constant volume flow this results in a reduced mass flow, ultimately affecting the temperature of the flame, and the emissions, at part load. LÄS MER
