Videos
  1. Getting rid of the bluff-body stabilize:  When the horizontal tangential swirl-air jets at the base of the burner are turned on they produce the divergent flowfield to allow the flame to detached from the bluff-body and freely propagates. Play
  2. Igniting a low-swirl burner can be done by spark (play spark video) or by a pilot (play pilot video)
