The possible hazardous consequences of large spills of liquefied natural gas (LNG) are currently under investigation by our Laboratory, under the Liquefied Gaseous Fuels Spill Safety Program (LGFSSP). One of the important aspects of the problem is the actual burning of the cloud and all the potential outcomes resulting from it. Described here, are current experimental efforts in this area, both in small-scale laboratory experiments and large-scale field tests. The results of laboratory-scale experiments conducted in semiconfined geometries suggest a strong role of obstacles in the flow. These obstacles can produce turulence in the flow, and thus, accelerate the flame to several times the laminar burning velocity. The large-scale vapor burn tests in the unconfined cloud have not yet been adequately analyzed, but they show some interesting features which are also discussed.
