4.12 Insert control movable brake disc
Insert control is used to achieve a pressure drop over the brake disc as
favourable as possible in the various power stages.
3- nozzles
The insert control sets the brake disc mode between Step 2 and Step 3
using a hydraulic piston. There are two adjustments to be made on the insert
a low load adjustment and a high load adjustment.
Low load
The low load adjustment takes place by changing the guide
rail’s mounting to the hydraulic piston. This takes place using
a locking screw located through an oval hole. In the default
setting, the value that is read in the table (XX) is used for the
setting values for the chosen power for step 2. During operation,
the insert is adjusted in order to achieve the best function.
Undo the locking screw (C).
Set the desired position on the scale (A) by pushing the disc in
the desired position.
Tighten the screw (C).
High load
The high load setting takes place by adjusting the hydraulic
piston’s length of stroke using set screw (D). Loosening the set
screw increases the length of stroke while tightening it reduces
the length of stroke
Set the desired position on the scale (A) using the set screw (D) (left turn
reduces pressure loss, the brake disc is moved outward).
If pulsation occurs, the changed pressure drop over the brake disc may
result in the pulsation stopping
4.13 Air setting
When the burner’s power stage has been selected, check the setting values
for air dampers in table (XX). Read the damper angle for each of the power
stages. This must then be used when the settings are made in the burner’s
control system 16520598(XX
)
Check the air settings by conducting a fl ue gas analysis.
