Nozzle assembly control, brake
plate

The nozzle assembly control is used to achieve the most favourable pressure

drop across the brake plate as possible in the various power stages.

2 nozzles

The nozzle assembly control is manually adjusted in order to

achieve optimal pressure loss for good combustion. Brake plate

position is controlled primarily by the second stage effect.

Set the desired position on the scale (C) using the set screw (D) (left

turn reduces pressure loss, the brake plate is moved outward).

If pulsation occurs, the changed pressure drop over the brake plate

may result in the pulsation stopping
