| contents | Flashback Avoidance in Swirling Flow Burners Marco Osvaldo Vigueras-Zúñiga Nicholas Syred Agustín Valera-Medina Daniel De la Rosa-Urbalejo Ingeniería Lean premixed combustion using swirling flows is widely used in gas turbines and combustion. Although flashback is not generally a problem with natural gas combustion, there are some reports of flashback damage with existing gas turbines, whilst hydrogen enriched fuel blends cause concerns in this area. Thus, this paper describes a practical approach to study and avoid flashback in a pilot scale 100 kW tangential swirl burner. The flashback phenomenon is studied experimentally via the derivation of flashback limits for a variety of different geometrical conditions. A high speed camera is used to visualize the process and distinguish new patterns of avoidance. The use of a central fuel injector is shown to give substantial benefits in terms of flashback resistance. Conclusions are drawn as to mitigation technologies. 2014 artículo científico 1405-7743 https://www.redalyc.org/articulo.oa?id=40431742011 en http://www.redalyc.org/revista.oa?id=404 Ingeniería.
