文摘
- •
Extended stability limits of inverse nonpremixed O2/CH4 coflow flames are found.
- •
Stable, attached flames and oscillating, near-blowout flames are observed.
- •
Direct flame and OH∗ chemiluminescence images indicate no steady liftoff flame.
- •
Reasonable levels of NOx emissions are observed.
- •
Inverse nonpremixed O2/CH4 coflow flames are acceptable for practical applications.
