Researchers create 17-foot fire vortex that burns oil slicks faster and cleaner

At the Texas A&M Engineering Extension Service Brayton Fire Training Field, a three-sided frame was erected to channel air around a 1.5-metre oil slick, producing a 17-foot-tall fire whirl. The rotating flame burned the crude roughly 40% faster than conventional pool fires and left as much as 95% of the fuel consumed, while emitting about 40% less soot. The team attributes the efficiency to the vortex’s ability to draw oxygen along the flame’s height, acting as a natural turbocharger.

Although the results suggest a faster, cleaner way to tackle offshore spills, the phenomenon remains sensitive to wind speed, oil depth and surrounding structures, limiting immediate deployment. Future work will focus on portable rigs that can safely generate the whirl in real-world marine conditions. The study, led by Elaine Oran, Qingsheng Wang and Michael Gollner, appears in the journal Fuel and was funded by the Bureau of Safety and Environmental Enforcement.
