Firing rates

The MAXIMUM OUTPUT is chosen from within the continuous
diagram area (Fig. 2).
The MINIMUM OUTPUT must not be lower than 3500 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
 secondary air damper fully open and primary air damper with
55 ° opening
 Partial head opening (obtained by adjusting the pins position
13 Fig. 6 on page 11 - from the maximum forward / retraction
closed position of 20 mm).
