COEN ECO-JET

This is a coen eco jet firing natural gas at sub 9 PPM NOx. The burner struggled to reach emissions, but overall the flame was stable. You will notice the burner had a strong and rich core in which the flame is anchored to. The burner peripheral gas (known as outer) introduces the remaining fuel to the burner. Typical fuel split could be 20% core and 80% outer.
