5.3 Insert control, movable brake plate
The insert control is used to achieve the most favourable possible pressure
drop over the brake plate in the various power stages.
3 nozzles
The insert control sets the brake plate mode between Step 2 and 3 using a
hydraulic piston. There are two adjustments to be made on the insert – low
load and high load adjustment.
Low load
The low load adjustment is made by changing the guide rail’s
attachment to the hydraulic piston. This is done using a locking
screw through an oval hole. For the basic setting, the value read
from the table (XX) is used for the setting values for the selected
power for step 2. During operation, the insert is adjusted in order
to achieve optimal functionality.
• Loosen the locking screw (C).
• Set the desired position on the scale (A) by pushing the
plate in the desired position.
• Tighten the screw (C).
High load
The high load setting is made by adjusting the hydraulic piston’s
stroke length using the set screw (D). Loosening the set screw
increases the stroke length while tightening it decreases the
stroke length.
• Set the desired position on the scale (A) using the set screw (D) (left
turn reduces pressure drop, the brake plate moves outwards).
• If pulsation occurs, the changed pressure drop over the brake plate
may stop the pulsation.
5.4 Air setting
When the burner’s power stage has been selected, check the setting values
for air dampers in the diagr§am. 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.
Check the air settings by conducting a fl ue gas analysis.
