U.S. Patent 20050126755, issued 2005.


A method and apparatus is provided for flame stabilization immediately downstream of a plurality of discrete fuel and air streams, prior to the mixing of the fuel and air, thereby preventing auto-ignition and flashback events. Coplanar and interspersed discrete fuel and air streams are introduced into a multiple channel monolith that imparts a swirl to the fuel and air streams, promotes immediate mixing, and initiates recirculation of the fuel and air mixture in a downstream combustion zone while promoting micro-scale vortex breakdown.
