1.4 Flue gas recirculation (optional)
The flue gas recirculation (FGR) reduces the NOx content of flue gases. A certain
proportion of flue gas is led back to the combustion chamber, which causes the flame
temperature to drop. This influences the NOx content of flue gas.
In general, the amount of recirculated flue gas must be adjusted to the smallest
possible quantity needed to obtain the required NOx rate. The flue gas quantity is
adjusted with the throttle valve located on the FGR pipe.
If the quantity of recirculated flue gas is excessive the flame may become instable and
the CO rate may increase. The amount of flue gas to circulate is set on the control
panel. To optimize the result, burner is adjusted to operate according to preset FGR-
curves.
