7. Adjust full load
When adjusting, the ratings data given by the boiler manufacturer and the capacity
graph of the burner should be observed.
The burner has been factory pre-sized for a specific oil throughput, see burner data
sheet.
Only in conjunction with frequency converter
Select speed at full load as low as possible, but not less than 80 %. Observe flame
stability.
Set pump pressure and oil quantity regulator position to the data given on the
burner data sheet.
Determine oil throughput, if necessary adjust position of oil quantity regulator
(Burn) until the oil throughput required is achieved.
If the burner is equipped with an adjustable mixing head:
Set auxiliary actuator for mixing head (Aux1) to diagram, see installation and op-
erating manual of burner.
Alternately adapt combustion values via the air damper setting (Air) and if ne-
cessary the speed (FC).
Check combustion values
Determine combustion limit and set excess air [ch. 7.9].
Only in conjunction with flue gas recirculation
If the burner is later operated with flue gas recirculation, the recirculated flue gas
reduces the excess air.
Set excess air 25 ... 30 % above the combustion limit to ensure sufficient com-
bustion air during the commissioning of the flue gas recirculation.
On burners with separate combustion air fan, the air dampers (Aux2) in front of the
FGR connection housing must also be slightly closed [ch. 6.15.1.2].
Set excess air 25 ... 30 % above the combustion limit.
Close air dampers in front of FGR connector housing (Aux2) until the O
reduces by approx. 0.4 % points.
Increase the O content again to the previous value using the air influencing ac-
2
tuators, whilst observing the flame stability.
The pump pressure must not be altered once this work has been completed.
8. Re-define point 1
Drive to point 1 in menu Point, whilst observing the combustion values.
Check combustion values and correct if necessary.
Carry out load apportionment [ch. 7.11].
To allow a reduction of MinLoad after commissioning, point 1 should be set below
the required partial load.
