What you're seeing is a phenomenon called a fire tornado.

Fire tornadoes can either be vortices separated from the main body of flame, burn within the area, or just a vortex of flame by itself. Notable fire whirls are the one produced by an earthquake in Japan on 1923, killing 38,000 in 15 minutes. Another one is the fire whirl that developed after lightning struck an oil storage facility in California in 1926. Usually however fire tornadoes result from wildfires.
