Technology: How RVC Technology WorksRecirculating Vortex Combustor ("RVC")
Challenge:
- Flame stabilization requires creation of low velocity regions
- Low emissions requires lean conditions (excess air)
- But lean conditions cause instabilities, flame blow out

Idea:
- Trap the recirculation zone between two physical bodies to extend lean flammability limits - "Trapped Vortex Combustor"
- The cavity flow is protected from the surrounding flowfield
Lean Flame Inc. has developed its own superior version Re-circulating Vortex Combustor - "RVC"
