Figure 6‐4: Example of Typical O
The curves above illustrate traits that are common to most nozzle mixing burners. These are:

Wide stability band ‐ 8% O

Curves decrease in %O

1% O or more between the O


O Control Curve close to rich limit (minimize %O


Curves are set up for efficiency (NOx emissions are not a priority)

LMV52.240 O trim system adequate for this type of setup
