  1. 1. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Sanger Shinwari; [2023]
    Keywords : Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

    Abstract : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. READ MORE

  2. 2. Ride through Capability of medium-sized Gas Turbine Generators : Modelling and Simulation of Low Voltage Ride through Capability of Siemens Energy's medium-sized GTG and Low Voltage Ride through Grid Codes requirements at point of connection

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

    Author : Daniel Almailea; [2023]
    Keywords : Gas Turbines; Synchronous Machines; Generators; Turbogenerators; Fault Ride Through FRT ; Low Voltage Ride Through LVRT ; Grid Codes; Frequency; Inertia; Generator Inertia; Power System; MATLAB; Simulink; Modeling; Excitation System; Automatic Voltage Regulator AVR ; Saturation Curve; Capability Curve; Load Angle; Siemens Energy.;

    Abstract : In order to reduce emissions and achieve sustainable energy systems, renewable energy is increasingly being integrated into the power grid. However, the integration of renewable energy into the grid poses several challenges, including maintaining a stable power supply under changing and unpredictable conditions. READ MORE

  3. 3. Hydrogen-Methane combustion modeling in the burner of the SGT-800 Siemens Energy gas turbine

    University essay from KTH/Teknisk mekanik

    Author : Nikolaos Bozikis; [2022]
    Keywords : Engineering mechanics; fluid dynamics; CFD; combustion modeling; industrial gas turbines;

    Abstract : Industrial gas turbines constitute an integral part of today’s electricalpower production infrastructure. Reacting gas flows in these machines arevery interesting and complex in nature since they exhibit highly turbulentbehaviour which is strongly coupled to the chemical reaction dynamics. READ MORE

  4. 4. Geometrical Improvement of Fuel Nozzle Locations in the SGT-750 Gas Turbine : An investigation into fuel-air mixing in main channels 1 & 2

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Aryan Delir; [2022]
    Keywords : gas turbine engines; turbofan; combustion; SGT-750; flashback; hydrogen; natural gas; premixing; fuel-air mixing; computational fluid dynamics; CFD; turbulence modelling; NOx emission; lean premixed mixture;

    Abstract : This study was conducted on SGT-750, which utilizes can type fourth generation DLE burner, developed at Siemens Energy AB, in Finspång, Sweden. The aim of this study is to obtain a flat fuel profile at the outlet of main channel 1 and main channel 2, demonstrating a proper mixing of fuel and air in the main channels leading to reducing local high-temperature points, and thus, reducing thermal NOx emissions.

  5. 5. Aerothermal and Kinetic Modelling of a Gas Turbine Dry Low Emission Combustion System

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : David Håkansson; [2021]
    Keywords : Gas turbine; combustion; one-dimensional combustion simulation; network model; general network model; NOx emissions; hydrogen; Gasturbin; förbränning; endimensionell förbränningssimulering; nätverksmodell; generell nätverksmodell; NOx-utsläpp; väte;

    Abstract : Growing environmental concerns are causing a large transformation within the energy industry. Within the gas turbine industry, there is a large drive to develop improved modern dry-low emission combustion systems. The aim is to enable gas turbines to run on green fuels like hydrogen, while still keeping emission as NOx down. READ MORE
