Control Curves ‐ Nozzle Mixing Burner (No or Low % FGR)
The curves above illustrate traits that are common to most nozzle mixing burners. These are:

Wide stability band ‐ 8% O
2
or more between the rich and lean limits

Curves decrease in %O
2
from low fire to high fire

1% O
2
or more between the O
2
Ratio Control Curve and the O
2
Control Curve (accurate Lambda
Factor)

O
2
Control Curve close to rich limit (minimize %O
2
to maximize burner efficiency)

Curves are set up for efficiency (NOx emissions are not a priority)

LMV52.240 O
2
trim system adequate for this type of setup
