  1. 16. Simulation of Gas Channel Temperatures during Transients for SGT-800

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Tobias Johansson; [2016]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE

  3. 17. Development of a Simulation Methodology for Gas Turbine Combustion

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

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

    Abstract : 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. READ MORE

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

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Johan Sjölander; [2015]
    Keywords : Combustion; gas turbines; CFD;

    Abstract : 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.

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

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE

  6. 20. VGV optimization for performance

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Sara Ling; Ted Sönne; [2014]
    Keywords : Twin-shaft; Tropical matched; Performance; Gas turbine; Ambient temperature; Variable guide vane; Siemens; Technology and Engineering;

    Abstract : Today’s market for gas turbines is very competitive and it is important to constantly improve the performance of the engines. It is commonly known that gas turbines have better performance at low ambient temperatures than at high ambient temperatures. READ MORE
