Deviating values on request
(N.B.: the lower operating point must also be within the working field.)
Boiler furnace
pressure
Selection of the nominal burner capacity within the nominal capacity area marked in the working
field. Deviating nominal capacities on request. At burners with FQ higher furnace back pressure by
rise of the motor frequency to > 50 Hz up to the max. capacity limit.
