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

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Aryan Delir; [2022]
   Nyckelord :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;

   Sammanfattning : 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. Network Modeling Application to Laminar Flame Speed and NOx Prediction in Industrial Gas Turbines

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära; Linköpings universitet/Tekniska högskolan

   Författare :Seyedeh Sepideh Marashi; [2013]
   Nyckelord :Gas turbine; combustion; NOx; emissions; laminar flame speed; burning velocity; hydrogen; network modeling; reactor network modeling;

   Sammanfattning : The arising environmental concerns make emission reduction from combustion devices one of the greatest challenges of the century. Modern dry low-NOx emission combustion systems often operate under lean premixed turbulent conditions. LÄS MER
