Firing rates

The MAXIMUM OUTPUT is chosen from within the continuous
diagram area (Fig. 2).
The MINIMUM OUTPUT must not be lower than 4000 kW as in-
dicated in the diagram (Fig. 2).

Air side pressure drop

The air pressure based on the output developed by the burner is given by the curves in Fig. 3.
Pressure measured upstream of the air dampers with:
 combustion head at 0 mbar
 air temperature 20°c
 barometric pressure at 1013 mbar
 air dampers at the maximum opening
 total head opening (obtained by adjusting the pins position
from the maximum forward / retraction closed position of
140÷150 mm).
