Abstract
A mechanism for generating a flame jet has a volume formed of at least one vertical structure and two opposing horizontal structures. A rotatable fan is located within the volume, and is rotatable in a plane generally parallel to the planes of the horizontal structures. The mechanism also contains means for igniting a combustible gas which is contained within the volume, to propel a flame jet outside of the volume.
