Tornado Combustor
with plasma enhancement
| |
As a combination of known and proven for rocket engines Reverse Vortex Flow Technology, and own outstanding solutions APT has developed and patented (U.S. Patent Applications US2008/0056961 A1, US2008/0245749 A1, and 11/843942, International Applications WO 2008/029303 A2 and WO 2008/122849 A2) a Triple Helical Flow Vortex Reactor with several innovative plasma tools, including spatial arc, plasma pilots with transient non-thermal arcs, and plasma fuel nozzles.
Plasma Assisted Tornado Combustor presents at the moment the most advanced and promising among known combustion and fuel reformation technology with the following main advantages:
- Simple tubular and annular designs
- Efficient internal mixing of fuel and oxidizer
- Stable combustion with extremely wide flammability limits - up to λ = 27
- Simple air swirler and fuel injectors
- Cold walls and exhaust nozzle (by 140 C)
- One digit NOx emission (propane tests, 15% oxygen)
- Cheaper materials for combustor fabrication
- Opportunity to feed fuel through the liner wall
- Possibility to provide a multi-stage combustion process
- Proven integration with internal and external plasma sources, including RF and Microwave for volumetric streamer discharge formation
- Simple conversion into the flexi-fuel combustor and fuel reformer
Several full-scale low and hight pressure (up to 10 Bar) Tornado Combustors (ID up to 143 mm) with spatial arc, plasma fuel nozzle and other plasma sources are currently under comprehensive tests in the U.S. Department of Energy, APT and other institutions worldwide. | |
