Trapped-vortex approach for syngas combustion in gas turbines

3D Computational Fluid Dynamics analysis reveals ideal placement for the inlets to create the energetic vortex


The increasing demand to reduce the consumption of fossil fuels and also of carbon dioxide emissions is fueling the research for alternative approaches to energy generation. Using trapped-vortex technology to burn syngas in gas turbine burners potentially offers several advantages over other approaches: it makes it possible to burn a variety of fuels with medium and low calorific values; the NOx emissions have very low levels without dilution or post-combustion treatments; it provides extended flammability limits and improves flame stability. The systems used so far generate a pilot flame by means of combustion in cavities to create premixed high-speed flows. This technical article presents a study to design a device that operates entirely on the principle of trapped vortices that intrinsically improve the mixing of hot combustion gases with fresh mixture, a characteristic that is essential both to diluted combustion and to Moderate or Intense Low-oxygen Dilution (MILD) combustion.
