  1. 1. 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.

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

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Jonathan Lönning; [2016]
    Keywords : ;

    Abstract : 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). READ MORE

    Keywords : CFD; Ansys; Fluent; CFX; Mesh optimization; DLE burner; Siemens; Mixing;

    Abstract : Every computational fluid dynamics engineer deals with a never ending story – limitedcomputer resources. In computational fluid dynamics there is practically never enoughcomputer power. READ MORE

  6. 5. Numerical Study of NOx and Flame Shape of a DLE Burner

    University essay from Mekanisk värmeteori och strömningslära; Tekniska högskolan

    Author : Naser Hamedi; [2012]
    Keywords : CFD; combustion; NOx emission; flame shape; burner;

    Abstract : For natural gas combustion, there is a large amount of experience in the gas turbine industry. However, much of the design work is based on costly combustion tests due to insufficient accuracy of existing prediction tools for data such as emissions and effects due to fuel composition. READ MORE
