Flashback avoidance analysis using geometrical constrictions in a tangential swirl burner

The flashback analysis in Gas Turbines for Power Generation has been of great concern for manufacturers and researchers in the last decade. This is due to the increased interest in using biofuels and enriched hydrogen combustibles for emission reduction and economical alternatives to fossils. This paper analyses experimentally and numerically the phenomenon in a Tangential Swirl Burner under different conditions in order to increase the understanding of the phenomenon to reduce its impacts in real gas turbines.
