6. AIR DAMPER ADJUSTMENT

The air dampers adjustment shall be set each time in relation with the nozzles delivery and the combustion chamber 
pressurization.

Fig. 2 shows the placement of the air dampers as fig. 3 their correspondent hydraulic jacks.
To open or close the air dampers proceed as follows: 
loose the ring nut 1), turn clockwise the exagonal body 2) in order to decrease the air flow, 
and counterclockwise to increase it.
The right adjustment of the air dampers may be detect by checking the combustion results 
in the three stages of burner operation.
To check the combustion during the different stages, the commutator should be set to the 
position corresponding to the burner stage to be controlled.

 nozzle hourcounter from those indicated in the 1

st

 nozzle hourcounter you 

could know how many hours the burner has been performing only at 1

st

 stage; the same procedure to detect the per-

formance hours of the 2

hourcounter.
The hours of 3
