min. value control (WD200)
O
2
ratio control can be set after setting the ratio curve.
Ratio curve air amount should be approx. 1 % higher than O
2
ratio
control, so that environmental changes do not set residual oxygen level
below O
2
trim control level.
Ratio curve should be as smooth as possible. If the curve has sharp breakpoints, set
one additional point to smooth the curve. Even ratio curve improves O
2
ratio control.
In dual-fuel burners, set the O
2
ratio control individually for both fuels, and they are not
correlating.
Start O

ratio curve by setting O

Set O
2
min. value control as low as possible to ensure a high availability. O
2
min. value
is between the permanently non-hazardous range and the potentially hazardous range.
O
2
ratio curve is set at lowest 0.5 %–1 % above O
2
min. value, so during normal burner
operation this level should not be reached.
