Control Curves in Figure 6 ‐ 4 (above)
The Lambda Factor curves serve as a tool to evaluate how accurate and repeatable the fundamental
mechanical systems of the burner are and how well all the curves were commissioned. In general, the
Lambda Factor curve should be as constant or "flat" as possible. The actual numerical value is not
important, but the consistency between points is. An approximate guide for evaluation of the Lambda
Factor:

Difference in Lambda Factor between adjacent points ‐ > lower numbers are better. Max = 0.35
(Higher numbers may lead to O
2
trim deactivations on some burners during modulation).

Standard Deviation of all points on the curve ‐ > lower numbers are better. Max = 0.30 (Higher
numbers may lead to O
2
trim deactivations on some burners during modulation).
